We’re working with a high-growth, AI-first fintech that’s quietly building something pretty special and now looking to add a Senior Full Stack Engineer to their team.

- Modern backend frameworks and distributed systems
- Cloud-native infrastructure (AWS, Kubernetes)
- Strong focus on observability, reliability and clean architecture
What they’re looking for:
- Strong experience as a Full Stack or Backend leaning engineer
- Confidence working with TypeScript (or similar high-level languages)
- Curiosity and enthusiasm for AI-assisted development
- People who ask great questions and enjoy solving meaningful problems
Why it’s interesting:
- AI isn’t a side project here, it’s central to how the team operates
- Real ownership and impact from day one
- Mission-led product
- Hybrid working, 2 days per week in a central London office
Salary - Up to ÂŁ100k
If you’re someone who’s curious about where software engineering is heading, and want to be in a team actually pushing that forward, this is worth a conversation.
