Software-as-a-Medical-Device (SaMD) Engineer Jobs UK 2026

The Short Answer

A Software-as-a-Medical-Device (SaMD) engineer in the UK builds software that is itself a regulated medical device — diagnostic apps, AI-driven radiology tools, digital therapeutics and clinical decision-support systems — rather than software that merely sits next to one. In 2026, base salaries typically run from £45,000 for junior engineers to £130,000 for seniors, with lead and principal roles reaching £180,000 at scaled medtechs and large OEMs. Top UK employers include Kheiron Medical and Brainomix in Oxford, GE HealthCare in Amersham, Philips Healthcare UK, Siemens Healthineers UK and CMR Surgical in Cambridge. Engineers work to IEC 62304 for software lifecycle, ISO 13485 for the quality management system and ISO 14971 for risk management, under the MHRA in the UK and the FDA where products target the United States. The MHRA's expanded AI Airlock programme, now backed by a multi-year funding settlement announced in April 2026, is generating real-world regulatory pathways for AI-driven SaMD. Demand remains firmly above supply.

What Is a SaMD Engineer?

A SaMD engineer builds software that meets the regulatory definition of a medical device — software intended to be used for one or more medical purposes, performing those purposes without being part of a hardware medical device. The category covers diagnostic mobile apps, AI tools that read radiology images, software that recommends insulin doses, mental health digital therapeutics with clinical claims, and decision-support modules embedded in hospital systems. It excludes general wellness apps, electronic health record front-ends and pure clinical workflow tools, though the line is not always obvious.

The work differs from standard healthcare software engineering in that the software itself is the regulated product. Every requirement traces to an intended use; every code change is risk-assessed; every release is accompanied by design history file documentation that an auditor can read. Engineers work inside a quality management system aligned with ISO 13485 and follow the IEC 62304 software lifecycle, which assigns each software item a safety class (A, B or C) that drives the rigour of testing, documentation and configuration control.

In practice, UK postings ask for production software experience in Python, C++, Rust or TypeScript, depending on the product, plus working familiarity with the standards stack: IEC 62304, ISO 13485, ISO 14971 risk management and, increasingly, IEC 82304-1 for health software products. Engineers building AI-driven SaMD also work to draft guidance under the MHRA AI Airlock programme and align with the principles set out in the UK's emerging AI-specific medical device framework.

Why Is SaMD Hiring Holding Up in 2026?

Hiring for SaMD engineers has stayed resilient through 2025 and into 2026 despite a wider cooling in healthcare technology funding. Three forces explain the gap. First, the MHRA's Software and AI as a Medical Device Change Programme has clarified the UK regulatory pathway enough that established medtechs and well-funded scale-ups are willing to invest in long product cycles again. Second, the NHS digital pivot — Federated Data Platform rollout, expanded use of AI-assisted diagnostics in radiology and stroke pathways, and growing procurement under the Digital Technology Assessment Criteria (DTAC) — continues to pull qualified suppliers into market. Third, transatlantic demand for FDA-cleared AI SaMD has not slowed; UK engineering teams remain competitive on cost and clinical evidence depth.

The MHRA's AI Airlock regulatory sandbox, expanded in April 2026 with £3.6 million of additional funding over three years from the Department of Health and Social Care, has played a meaningful role. Phase two, due to complete in spring 2026 with reports in the summer, has tested large language models, voice tools and specialised diagnostics for cancer and rare diseases, generating evidence that will feed into the UK's forthcoming AI-specific medical device framework. For engineering teams, that means real precedent for pre-determined change control plans (PCCPs) — the mechanism that lets a model be retrained and redeployed without a fresh marketing submission — which makes AI SaMD products genuinely shippable rather than perpetually pre-launch.

EU MDR remains a complication for UK firms selling into Europe, and the EU AI Act's high-risk classification overlaps awkwardly with the medical device regulation. Most of the UK employers below now run parallel UKCA and CE marking processes, which has expanded the regulatory affairs and SaMD QA headcount considerably.

Which UK Employers Are Hiring SaMD Engineers?

The UK SaMD employer base splits into three groups: large global OEMs with UK engineering sites, scaled UK medtech specialists, and growth-stage scale-ups. Among large OEMs, GE HealthCare maintains a substantial software and imaging engineering presence in Amersham, recruiting for AI radiology and imaging workflow roles. Philips Healthcare UK hires across London and Cambridge for imaging informatics and patient monitoring software. Siemens Healthineers UK runs SaMD-adjacent engineering particularly in diagnostic imaging and laboratory diagnostics, with sites in Frimley and Camberley.

In the UK medtech specialist tier, Kheiron Medical (London) continues to recruit for its breast cancer screening AI products; Brainomix (Oxford) hires for its stroke and lung imaging platforms, both UKCA and FDA-cleared; CMR Surgical in Cambridge builds the Versius surgical robotics platform and recruits software engineers across both device firmware and SaMD-adjacent applications; Smith+Nephew across Hull, York and London recruits for orthopaedic digital tools and wound care imaging software. IBEX Medical Analytics has a growing UK presence around digital pathology AI.

Scale-up hiring is concentrated in London, Oxford and Cambridge. eMed Healthcare (the rebrand of Babylon Health's remaining UK assets, now part of the eMed group) recruits for at-home diagnostic SaMD. Skin Analytics, in London, builds dermatology AI used by NHS trusts. Ada Health UK runs UK engineering for its symptom assessment platform. Healx in Cambridge applies machine learning to rare disease drug discovery with some SaMD-classified outputs. Owkin's UK team works on federated learning for oncology, and Lumeon focuses on care orchestration software with elements that increasingly cross the SaMD threshold. Cera Care, while primarily a care technology platform, recruits engineers for clinical decision-support modules under SaMD scope.

What Salaries Should SaMD Engineers Expect in 2026?

Pay is above the general software engineering median because the regulatory and standards literacy required narrows the candidate pool considerably. In our reading of UK postings and recruiter benchmarks through early 2026, base ranges sit roughly as follows.

Bonuses and equity at scaled medtechs and large OEMs can add a further 10–25% to total compensation. Engineers with demonstrable IEC 62304 experience on a Class B or C product, and prior involvement in an MHRA or FDA submission, command the upper end of each band — recruiters routinely describe this profile as the rarest combination in the UK market. ITJobsWatch data on IEC 62304 postings, while a small sample, consistently shows median advertised salaries above the wider software engineering median, with senior medical device software roles closing well above £100,000. Day rates above £900 are common for short-term engagements supporting submissions, regulatory remediation or design history file work; longer contract engagements typically settle in the £600–£800 range inside IR35.

How Does SaMD Engineering Compare to Adjacent Roles?

The titles "SaMD engineer", "medical device software engineer" and "healthcare software engineer" are used loosely in UK adverts, but the day-to-day differs meaningfully.

The shorthand is that a SaMD engineer treats the software as the product the regulator approves; a medical device software engineer treats the software as the brains of a regulated hardware product; a standard healthcare software engineer builds clinically-adjacent software that must be safe and compliant under NHS digital frameworks but is not itself a medical device. Pay reflects the regulatory load, but so does the time-to-market: SaMD release cadences remain measured in months or quarters rather than weeks.

What Technical and Regulatory Skills Matter Most?

UK postings in 2026 converge on a recognisable stack. On the standards side, employers expect working knowledge of IEC 62304 (medical device software lifecycle), ISO 13485 (quality management system), ISO 14971 (risk management) and IEC 82304-1 (health software products). Familiarity with the second edition of IEC 62304, which broadens scope and clarifies expectations around legacy software and SOUP — software of unknown provenance — is increasingly assumed. Awareness of the MHRA's Software and AI as a Medical Device guidance and the principles emerging from AI Airlock work is now common in senior adverts.

On the technical side, Python dominates for AI-driven SaMD and image analysis; C++ and Rust appear where safety-critical or performance-sensitive components require them, with MISRA C still relevant on legacy embedded code paths. Healthcare-specific data standards — DICOM (often via pyDICOM) for imaging and HL7 FHIR for clinical data exchange — appear in most postings. Cloud-native SaMD work typically runs on Azure for Health, AWS HealthLake or, less frequently, GCP healthcare APIs, with private-region deployments increasingly common for NHS contracts.

For ML SaMD, employers expect MLflow or comparable model lifecycle tooling, plus the ability to evidence model performance, drift monitoring and re-training under a pre-determined change control plan. Test discipline matters more here than in most software roles: unit, integration, system and verification testing all map onto IEC 62304 obligations, and engineers are expected to write tests that auditors will read. Familiarity with at least one regulatory submission tool chain — Jama Connect, Polarion, Codebeamer or similar — is a recurring nice-to-have at mid-level and an expectation at senior.

Where in the UK Are These Jobs Concentrated?

The UK SaMD map has three clear anchors and a longer tail. Cambridge is the largest single cluster, driven by CMR Surgical, Healx, AstraZeneca-adjacent software activity and a long tail of life-science software firms on the Biomedical Campus and around the Science Park. Oxford comes second, with Brainomix and a growing constellation of imaging AI firms spinning out of the university; Owkin's UK team also has Oxford ties. London is the largest aggregate market by headcount, spanning Kheiron Medical, Skin Analytics, Ada Health UK, eMed Healthcare, Lumeon and the UK offices of Philips Healthcare and IBEX.

GE HealthCare's Amersham site (Buckinghamshire) remains a significant employer, particularly for imaging and contrast media-adjacent software. Smith+Nephew runs sites in Hull and York, with London for digital health teams. Manchester and Leeds host smaller but growing clusters, often linked to NHS trust academic partnerships and to the Northern Pathology Imaging Co-operative. Birmingham, while not the largest centre, hosts NHS Digital and NHS England engineering teams whose SaMD adjacency comes from procurement and assessment rather than direct device development. Remote and hybrid working is common at mid and senior levels but most teams expect one to three days a week on site, particularly when verification activities or clinical workshops are scheduled.

How Do UK Regulators and Industry Bodies Shape the Role?

The Medicines and Healthcare products Regulatory Agency is the central regulator. The MHRA's Software and AI as a Medical Device Change Programme has been the most consequential UK regulatory initiative of the last two years; its outputs feed directly into UKCA marking expectations and into the AI Airlock sandbox programme. The National Institute for Health and Care Excellence assesses clinical and cost-effectiveness for technologies the NHS procures, and the NICE Evidence Standards Framework for digital health technologies is increasingly cited in SaMD postings.

NHS Digital, now folded into NHS England's Transformation Directorate, runs the Digital Technology Assessment Criteria (DTAC) — the procurement gateway for any technology entering the NHS. While DTAC is not itself a medical device regulation, SaMD products generally need both DTAC clearance and UKCA marking to be deployed at scale. The British Standards Institution acts as the dominant UK notified body for medical devices, and is the route through which most UK SaMD products receive their UKCA assessment.

The Association of British HealthTech Industries (ABHI) is the main trade body and runs working groups whose outputs are often referenced in MHRA consultations. For products targeting the United States — which most growth-stage UK SaMD firms do — the US Food and Drug Administration's 510(k) and De Novo pathways are part of normal engineering planning, and engineers with US submission experience command a clear premium. The EU AI Act's high-risk medical device provisions are now in force, with implications that overlap, sometimes uncomfortably, with EU MDR for products selling into the European Economic Area.

What Career Paths Open from a SaMD Engineer Role?

SaMD experience travels well within healthcare technology and increasingly outside it, particularly into other safety-critical domains. The most common forward moves are into senior and principal engineering at scaled medtechs and large OEMs, where the compensation ceiling sits near or above £200,000 once equity and long-term incentives are included. A meaningful minority of SaMD engineers move into engineering management or into hybrid roles bridging engineering and regulatory affairs — director of software, head of SaMD engineering, or director of regulatory at scale-ups.

For founders, the path from senior SaMD engineer to chief technology officer of a medtech start-up is well established, particularly out of Cambridge and Oxford. Outside healthcare, SaMD experience increasingly maps into AI assurance roles in finance, automotive and defence, where the discipline of risk-based software lifecycle and traceable verification has obvious cross-application. Regulatory affairs is the other natural pivot; experienced SaMD engineers who shift into RA frequently end up at notified bodies, consultancies or in MHRA-adjacent advisory roles.

Frequently Asked Questions: SaMD Engineer Jobs UK

Do I need a medical or clinical background to become a SaMD engineer?

No. The majority of UK SaMD engineers come from a standard software engineering background and pick up the regulatory standards on the job. Clinical or biomedical degrees help in particular product areas — radiology AI, pathology, surgical robotics — but they are rarely a hard requirement. Employers value evidence of working under a quality management system and an ability to read clinical literature carefully far more than a clinical qualification.

What is the difference between SaMD and SiMD?

Software as a Medical Device is software that meets the definition of a medical device on its own. Software in a Medical Device, sometimes abbreviated SiMD, is software embedded in or controlling a hardware medical device — for example, the firmware in an infusion pump or the control software in a surgical robot. Both are regulated, both work to IEC 62304, but the SiMD work tends to involve more embedded systems and IEC 60601-1 hardware safety considerations.

Which certifications or training help the most?

Practical experience inside an ISO 13485 quality management system is the strongest signal. Short courses on IEC 62304 and ISO 14971 from BSI, TUV SUD or LRQA are widely recognised in UK postings. The MHRA's published guidance and the AI Airlock outputs are free and worth reading carefully. For engineers targeting US submissions, RAPS (Regulatory Affairs Professionals Society) materials on FDA 510(k) and De Novo pathways are routinely cited.

Can I work in SaMD as a contractor in the UK?

Yes, and the day-rate market for cleared SaMD experience is healthy, typically £600–£1,000 per day inside IR35 and higher outside where available. Most contract engagements support specific submissions, design history file remediation or post-market surveillance work. Employers prefer contractors who have already completed at least one UKCA or FDA submission cycle. Long-term contractor-only careers in SaMD are less common because permanent total compensation is competitive.

How does the MHRA AI Airlock affect day-to-day engineering work?

For most engineers, the immediate effect is more concrete guidance on AI-specific topics — pre-determined change control plans, performance monitoring, drift, post-market surveillance and intended-use boundary management. Teams whose products are accepted into AI Airlock cohorts work closely with the MHRA and an approved body during development, which compresses the regulatory feedback loop. Outputs from the programme are feeding into the UK's emerging AI-specific medical device framework, expected through 2026.

Is remote working realistic for SaMD roles?

Hybrid is the norm; fully remote is possible but less common. Verification activities, clinical workshops, supplier audits and design review meetings still tend to happen in person, particularly at OEMs and at firms with hardware-adjacent products. Most scale-ups expect one to three days a week on site. Engineers in regulatory affairs hybrid roles tend to have more flexibility than those whose work touches hardware verification or clinical evaluation.

How long does it take to move from standard software engineering into SaMD?

Most engineers who make a deliberate move are productive within six to nine months and considered to have meaningful SaMD experience after roughly eighteen months working under a quality management system on a regulated product. The transition is faster for engineers who already work in safety-critical domains — automotive, rail, aviation — because the underlying discipline of traceable requirements, hazard analysis and verification is similar.

What is the salary ceiling for SaMD engineers in the UK?

Permanent base salaries top out around £180,000 for principal and lead roles, with total compensation reaching above £200,000 at scaled medtechs and large OEMs once bonus and equity are included. Director-level engineering roles and CTO positions at growth-stage medtechs can move higher, particularly with equity. SaMD QA and regulatory specialists with strong submission track records command a clear premium of £10,000–£25,000 over comparable standard software roles.

Summary: Is a SaMD Engineer Role Right for You?

SaMD engineering suits software engineers who like working slowly and carefully on products where the cost of getting it wrong is measured in patient harm rather than churn. The pay is good and the role is durable through funding cycles because regulators and procurement gateways set a high floor on what gets built. If you find documentation, traceability and standards work tedious, this is not the right path; if you find them reassuring, you will probably enjoy it. UK demand through 2026 is concentrated in Cambridge, Oxford, London and the Amersham/Buckinghamshire corridor, with growing pockets in Manchester, Leeds and Hull. The MHRA's expanded AI Airlock programme and the UK's forthcoming AI-specific medical device framework should make the regulatory pathway clearer, not more complicated, for AI-driven SaMD specifically.
