Senior Software Engineer (Full-Stack - Python/TypeScript) in London

Our Future Health is an ambitious collaboration between the public, charity and private sectors, designed to help people live healthier lives for longer through better prevention, earlier detection and improved treatment of diseases. We will speed up the discovery of new methods of early disease detection, and the evaluation of new diagnostic tools, to help identify and treat diseases early, when outcomes are usually better. With over 2.5M volunteers across the UK, we’re now the world’s biggest health research programme of its kind, and our volunteer group is also more diverse than other, similar health research programmes.

Technology and data are central to our mission. Our systems power web sites, clinics across the UK, secure analytics and research systems, pipelines that process highly sensitive health and genetic data, and we are continuing to grow our engineering capability to support this ambition.

We are looking for a Full-Stack focused Senior Software Engineer to join our cross-functional Participant Engagement squad. You will be helping participants stay connected to Our Future Health, giving them clear, meaningful reasons to return to the platform, understand the impact of their involvement, and feel confident taking part in future research.

Our tech-stack includes Python, TypeScript, PostgreSQL, Terraform (IaC), running in Azure (Kubernetes and Azure AppService). Our engineers are full-stack, handling frontend, backend and infrastructure in a total ownership model - squads build and run it. Experimentation will be a key part of the role, so we’re looking for someone who brings initiative, is comfortable exploring ideas, and can help us validate what resonates before we invest in longer-term solutions.

The role combines practical engineering with opportunities to influence how engagement evolves, helping us deliver quick wins today while laying the groundwork for long-term impact on participant trust, confidence, and research readiness.

In this role, you will:

• Work in a small, growing team where you’ll contribute both to early design and hands-on delivery.
• Help shape and build the experiences that deepen participant understanding and motivation, making thoughtful decisions about what to develop, when to reuse, and how to optimise the journeys people already see.
• Design systems that encourage people to return, explore insights, share additional data, and take part in studies.
• Move across the stack, from front-end features built with TypeScript and modern frameworks to backend and data-driven work in Python, depending on what the problem calls for.
• Learn from real behaviour and iterate quickly based on what works.

This role will be fully hybrid with the expectation we get together in our Holborn, London office at least once per month.
