Senior Software Engineer - Application Engineering

We're looking for a Senior Software Engineer to join our Application Engineering team, a hands-on builder who takes real ownership of what they ship. You'll work end-to-end on features and initiatives, from design through to production, collaborating closely with our Data Engineering team who own the health data pipelines that power our platform. This is a dynamic, broad-reaching role for someone who thrives with autonomy. You'll be expected to lead initiatives technically, scoping, designing, building, and iterating, in a team where every contribution matters.

What you’ll be doing

• Building and improving features across the platform, with Python and Django at the core of our stack, while picking up other technologies as the platform and your work demands
• Writing well-structured, testable, production-ready code and holding yourself to a high standard of quality
• Collaborating with Data Engineering to understand platform capabilities and integrate effectively
• Working closely with Product and Design in scrum ceremonies, backlog refinement, and technical discussions, contributing your perspective, not just your code
• Participating in production support and incident management, debugging and resolving issues to keep our platform stable and performant
• Documenting what you build, clearly and consistently
• Helping define and evolve our backend engineering standards, staying current with the Python and Django ecosystem and bringing good ideas back to the team

What we’re looking for

• Strong Python and Django skills (or comparable Python web framework experience)
• Solid grasp of REST API design and SQL database modelling
• Comfort with relational databases and a good instinct for data modelling
• Solid experience with AWS, including containers and serverless technologies
• Working knowledge of message queuing and stream processing
• Experience with observability and CI/CD tooling such as Sentry, Datadog, or CircleCI
• A track record of delivering well-designed backend features end-to-end, independently
• Degree in computing or equivalent experience - we care more about what you've built than where you studied

Nice to have

• Experience with React and JavaScript/TypeScript
• Experience working with or alongside data engineering workflows, including tools like Airflow
• Experience with clinical or healthcare systems

Who you are

• A self-starter who doesn't wait to be told what to do next
• Genuinely care about code quality, reusability, maintainability, and scalability
• Excited by working in a small team where you wear several hats
• Someone who empathises with users and keeps their needs at the centre of every technical decision
• Motivated by the idea that the software you create could directly improve patient outcomes
