Job description

The role

This company is rebuilding property investment for landlords, end-to-end. Think company formation, accounting, mortgages, and property management, all integrated into one platform. They treat AI as a first-class citizen in engineering, not just in what they ship, but how code gets written and systems are reasoned about. They're backed by leading investors and manage significant assets for tens of thousands of users.

You’ll join a cross-functional product team in London. This isn’t just about implementing specs; you’ll shape the problems solved, not just how they’re built. Expect real ownership, moving ideas from concept to deployment. You’ll use AI tools as genuine leverage, helping define what an AI-native engineering practice looks like as the team scales. This role is for a builder who thrives on ambiguity, not just a ticket-taker.

The work

• Take full ownership of features, from concept to deployment, impacting a platform managing significant assets.
• Work across a modern full-stack: React, Remix, TypeScript on the frontend; Golang on the backend.
• Shape product direction, defining problems and solutions alongside product and design.
• Integrate AI tools into your daily development workflow, moving beyond basic autocomplete to genuine leverage.
• Contribute to defining and scaling an AI-native engineering practice.

What You Bring

• Proven experience as a full-stack engineer on user-facing products, comfortable across frontend and backend.
• Ability to frame business problems and think in trade-offs, not just technical solutions.
• Demonstrable experience using AI tools in your development workflow, with a clear understanding of prompting and reasoning.
• A track record of mentoring engineers and contributing to team growth.
• Strong testing habits: unit, integration, and end-to-end automation.
