53433Posted: 17/09/2026London, United KingdomPermanentSoftware Safety EngineerLocation: London — hybrid, 3–4 days per week in the officeType: Full-timeAbout the roleWe're working with a fast-growing organisation building a new approach to medical device certification.
The team combines clinical, technical and regulatory expertise with AI and software to help rigorous certification keep pace with product development at some of the world's most ambitious technology companies — without lowering the safety bar.
Its customers are developing innovative healthcare technology, including AI-enabled medical devices, clinical decision-support tools, digital therapeutics and other software-led products.
The business has grown rapidly, recently raised a Series B and is approaching 100 customers, with international expansion underway. This is an opportunity to join while there is still a huge amount to build.
The roleAs a Software Safety Engineer, you'll sit within the assessment team, assessing the software safety of medical devices as part of quality management and certification work.
You'll bring a strong background in software engineering, testing and safety-critical development to assess customers' products and processes. You'll review software lifecycle processes and technical documentation, identify risks and evidence gaps, explore failure modes and contribute to rigorous certification decisions.
You'll also use and help shape AI-assisted workflows to navigate evidence, develop questions, test hypotheses and surface inconsistencies for deeper review. You'll work closely with product, engineering and applied machine learning teams to improve these tools as AI capabilities evolve.
The goal is simple: help safe medical technology reach patients faster, without compromising the safety bar.
What you'll doAssess software lifecycle processes and technical documentationEvaluate software safety, risks, gaps and inconsistencies in technical evidenceReview software verification and validation activities and supporting evidenceApply your software engineering and safety-critical experience to certification assessmentsMonitor and act on regulatory insights from research, standards and guidanceUse AI-assisted tools to investigate evidence, explore failure modes and develop assessment questionsWork with product, engineering and machine learning teams to improve assessment workflowsContribute to expanding into new jurisdictions and certification frameworksCreate clear content explaining complex technical and regulatory topicsProvide technical and regulatory insight to customers throughout certificationWhat we're looking forRequiredDegree in computer science or a related discipline4+ years' experience in medical device or another safety-critical product environment, including manufacturing, auditing or research2+ years' experience developing safety-critical softwarePractical experience with: Software development lifecycle processesSoftware verification and validation testingSoftware configuration managementCybersecurityStrong technical judgement and the ability to understand complex software systems and identify meaningful safety risksExcellent written and verbal communication skillsPreferredKnowledge or formal training in relevant medical device software standards, such as IEC 62304 and IEC 81001-5-1Experience with medical device software certification, assessment, auditing or regulatory processesExperience with generative AI, including LLMs, embeddings, RAG, fine-tuning, evaluation or monitoringYou don't need experience in every area above. We're particularly interested in people with a strong software engineering and safety-critical background who are excited to apply that expertise in a rapidly evolving environment. How we workThe organisation provides independent, rigorous assessment, but doesn't see its role as simply being the "police". Customers are treated as partners, with the aim of helping ambitious teams understand requirements, identify issues early and move through certification efficiently while maintaining the safety bar.
The team values technical rigour, helpfulness and customer focus. It's a good environment for people who enjoy solving difficult problems, working directly with customers and moving quickly.
