Product Engineer

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.
