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

Our Future Health will be the UK\’s largest ever health research programme, bringing people together to develop new ways to detect, prevent, and treat diseases. We are a charity, supported by the UK Government, in partnership with charities and industry. We work closely with the NHS and with public authorities across all nations and regions of the UK.

Our plan is to bring together 5 million volunteers from right across the UK who will be asked to contribute information to help build one of the most detailed pictures we have ever had of people\’s health. Researchers will be able to use this information to make new discoveries about human health and diseases. So future generations can live in good health for longer.

We are looking for a Full-Stack focused Senior Software Engineer to join our cross-functional Participant Engagement squad . You\’ll 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.

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

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

As the work is still in its early stages, you\’ll often 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

RequirementsWe welcome applications from all who may not feel they match the full criteria, so if you have most of the below, we\’d like to hear from you:

Prior experience with Azure (ideally), AWS or GCP

Comfortable working with Infrastructure as Code, ideally with knowledge of Terraform

Knowledge of good data modelling and design patterns; in-depth knowledge of relational databases (e.g. PostgreSQL) and familiarity with other types of data store (blob, document, graph)

Expertise in modern, agile development practices like code review, TDD, CI/CD and pairing using tools like Git and GitHub

Experience of operationally managing software components once live, including observability, logging, metrics, error reporting, debugging and live incident management
