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

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 websites, 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 Senior Software Engineer to join our cross-functional Health Insights squad. Join us at an early stage as we develop a platform that delivers personalised health insights to millions of participants across the UK. You’ll help shape systems working with complex, sensitive health and genetic data, supporting meaningful, real-world outcomes.

In this role, you will:

• Help shape the architecture and direction of an early-stage platform
• Work on backend and data-intensive systems handling sensitive health data
• Contribute across backend, frontend, and infrastructure as part of a full-stack squad
• Support the evolution of the platform as it grows in scale, complexity, and impact

Our tech-stack includes Python, TypeScript, Next.js, 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.

As the platform grows, you’ll help evolve the system to support new types of data, increased scale, and more advanced processing needs, with the opportunity to influence how it develops over time.

At senior level, you’ll bring strong technical experience within your team, offering guidance and direction on key areas of engineering and architecture. You’ll support others through mentoring and collaboration, while also contributing to the wider technical direction of the organisation over time.

Responsibilities inc -

• Contribute to shaping both the product and the technology, bringing a user-centred, outcome-focused mindset and collaborating closely with product, design and other disciplines to deliver meaningful value to participants
• Hands-on development of new features, iterating on existing features, addressing product- or tech debt at the right time and contributing to continuously improving the quality of the code base
• Supporting your colleagues with pairing, code reviews, feedback, discussion, and other collaborative activities that help everyone reach high standards and result in the delivery of high-quality software products
• Engage in sessions for refining requirement and formulating architectural proposals in support of upcoming initiatives
• Engage in reflective sessions such as retrospectives to offer suggestions on how we can improve and help to drive change
• Collaborate with internal squads that use shared tooling built by the squad, and other platform squads
• Participating in live operations support, monitoring live systems and quickly and effectively reacting to potential incidents
• Participation and contribution into wider engineering initiatives that look to evolve highly effective ways of working that fit for Our Future Health and work for the benefit of the Our Future Health engineering community
