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.
This isn’t your typical “we use AI” environment. Engineering here is genuinely LLM-first. Think day-to-day development powered by tools like Claude Code and Codex, with engineers actively shaping how AI integrates into real production workflows.
What you’ll be doing:
- Owning features end to end across a modern full stack environment
- Building and scaling payments infrastructure across multiple markets
- Working closely with product and data to solve complex, real-world problems
- Playing a key role in evolving how the team leverages AI in software development
- Mentoring and raising the bar across engineering
Tech environment:
- TypeScript at the core, alongside Python and Ruby
- 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.
