Senior Full Stack Engineer | London | £120,000 - £160,000+ | Python | React | TypeScript
Location: London (hybrid)
- Backend: Python (strong typing, well-structured APIs - Django or FastAPI or Flask)
- Frontend: React, TypeScript
- Systems: Data modelling, integrations, platform architecture
Are you an engineer who thinks in systems, not tickets?
We’re working with a high calibre, early stage team building production grade software around AI systems. Not model building. Not prompt tinkering. The infrastructure, tooling, and platforms that make AI actually useful in the real world.
This is an environment for engineers who care about how things are built, not just that they work. A small team with high standards and some serious momentum.
What you’ll be doing:
- Designing and building well typed backend systems in Python
- Creating clean, scalable frontend architecture using React and TypeScript
- Owning data models, schemas, and system design end to end
- Integrating complex external systems and services into a cohesive platform
- Taking problems from idea to production without layers of process slowing you down
- Contributing to architecture decisions that shape the direction of the product
What they’re looking for:
- Strong full stack experience with Python and modern frontend frameworks
- Engineers who care about clean design, readability, and long term maintainability
- Experience building and scaling systems, not just shipping features
- Comfort owning ambiguous problems and turning them into production systems
- Product minded thinking and a bias for action
The ideal candidate is someone who leans into complexity rather than avoiding it, and gets real satisfaction from solving hard problems alongside sharp, thoughtful people. This means you're a strong communicator who can articulate ideas clearly without overengineering the explanation, and have the humour that keeps a startup environment enjoyable when things get intense.
If you’re interested in AI but more drawn to building the systems around it than becoming an AI engineer, this is exactly that sweet spot.
If that sounds like your kind of environment, drop me a message at imogen@sr2rec.co.uk.
