Product Engineer – London – £50K-65K
Avanti is working with a fintech hiring a Product Engineer in London that's rebuilding its entire engineering model around AI-native execution. Not "we use Copilot now." Actually rethinking how software gets built.
What You'll Actually Do
- Ship complete features weekly – discovery, build, test, live release. One week, start to finish
- Use Claude as your primary execution partner across the whole stack – context engineering, agent workflows, the lot
- Sit with real users. Understand the problem Monday, get feedback on what you built by Friday
- Work in a small co-located team with a PM and customers in the room – minimal handoffs, no ticket queues
- Mentor junior engineers on AI-native development and help pull the whole team forward
You Are
- 3-4 years in and already AI-native – not "I use Cursor sometimes" but genuinely can't imagine going back
- T-shaped enough to move across frontend, backend, and deployment without stopping to ask permission
- More interested in outcomes than code quality theatre
- Comfortable talking to customers because that's how you build things that work
- Probably frustrated at how slowly your current place moves
This Isn't For You If
- You think context engineering means writing better comments
- "That's a PM decision" is a sentence you say often
- You want to specialise deeper into one layer of the stack
- You need sign-off before shipping
The Details
Location: London, 3 days/week in-office Stack: TypeScript, React, Node.js, Python Interview: Call, then a short build session with the team. Fast turnaround.
Apply for immediate consideration.
