About the role

ABOUT US At Heim, we are reinventing how healthcare is delivered. We believe that healthcare is best delivered in the home of patients, and that we are at the cusp of a systemic shift away from hospital based care. Our mission is to expand access to in-person clinical care at home by empowering community nurses with technology that makes care delivery more efficient. We have created an AI native ecosystem that optimises the complex scheduling involved in delivering community based care, and are on track to automate every non clinical touchpoint for nurses. To date, our technology has powered our network of 400+ practitioners to deliver c. 30K appointments, and we have shown that our algorithms bring down the cost of at-home visits by c.35% whilst freeing up valuable time for care in doing so. We are growing fast and our ambitions are big – with new international markets on the roadmap, and strong investor backing. Our aim is to create the most productive, AI-enabled distributed clinical workforce working at the intersection of public and private health.By joining Heim, you will play a pivotal role in building the infrastructure that puts clinical care in the home. WHAT IT'S LIKE TO WORK AT HEIM We are reinventing how healthcare is delivered. Here are the things that shape your day-to-day: • Meaningful problems – we build systems that improve how organisations understand and care for people. The work is complex, applied, and grounded in real-world patient impact • High standards, low ego – you’ll work alongside thoughtful engineers, clinicians, and operators who care about clarity and good judgement • Speed with intent – we move quickly but deliberately. Clear ownership, evidence-based decisions, outcomes over output • Simple, elegant solutions – we have a strong bias towards code that is easy to reason about, hard to break, and built to outlast the sprint it was born in • Direct access to founders – you’ll have visibility into and input on the direction of the company WHAT MAKES THIS ROLE DIFFERENT This is a full-stack TypeScript role in the truest sense – you will own problems across the entire system, from UI to infrastructure. AI isn’t a feature here; it’s a first principle. We expect you to use agentic coding tools fluently (e.g. Claude Code, Cursor) and to be building your own views on where agentic workflows can meaningfully improve what we ship. You’ll be working on systems where the stakes are real: scheduling errors affect patient care, data quality issues affect clinical decisions, and downtime has consequences. That context sharpens every technical choice you make. WHAT YOU'LL DO Design and build product features end-to-end across the Heim tech stack – owning them from first principles to production • Architect and implement AI-powered workflows: scheduling optimisation, practitioner dispatch, clinical data enrichment, and agentic referral automations that reduce manual touchpoints for nurses • Own the full lifecycle of features – from TypeScript frontend through to backend services, infrastructure, deployment pipelines, and testing – without relying on separate DevOps or QA teams to close the loop • Build and maintain the APIs, services, and data models that underpin clinical operations – with the reliability and auditability a regulated environment demands • Collaborate with our product and clinical ops teams to translate ambiguous real-world problems into working software • Make pragmatic trade-offs between speed and quality, and advocate clearly when the trade-off isn’t acceptable • Contribute to the architecture and infrastructure decisions that will shape the platform as we scale to NHS Trusts across the UK and into new markets • Leave the codebase better than you found it – improving performanc
