Job description

Our client is redefining how software is created in the AI era — not by generating snippets of code, but by reimagining the entire process of how software is designed, built, and evolved.

Founded by a proven tech leader (the founder of one of Europe’s best-known DevTools companies) and backed by Index, Accel, GV, and Boldstart, this London-based Series A scale-up is pioneering what they call AI Native development — where AI isn’t a helper, it’s a core collaborator in building software.

They’re now looking for a Product Engineer to join the User Journeys team — someone who thrives at the intersection of engineering, design, and developer experience. You’ll help build the tools, workflows, and interfaces that will define how developers create in the future.

The Opportunity:

You’ll work across the stack to craft real-time, intuitive developer experiences — from fine-tuning collaborative UI interactions to designing new CLI tools and IDE extensions.

This isn’t a "just code what’s specced" role — it’s a chance to experiment, make architectural calls, and influence how millions of engineers might one day build software.

• Build AI-driven workflows, interfaces, and tools that transform how developers code.
• Pair with designers to refine the user experience in the Tiptap-based editor.
• Develop CLI tools and IDE extensions that connect developers seamlessly with the platform.
• Architect real-time systems for streaming and collaboration across the platform.
• Write clear, opinionated technical docs and decision records that shape product direction.
• Help define and implement end-to-end testing and deployment strategies.
• Frontend: React (Remix, SSR, and modern frameworks)
• Tooling: Tiptap, ProseMirror, CLI, IDE extensions

What You Bring:

• ~6+ years building complex products in collaborative, cross-functional teams.
• Experience working with TypeScript and strong intuition for developer experience.
• Proven ability to design, scale, and maintain production APIs.
• Comfort in high-autonomy, fast-moving environments — ideally early-stage startups.
• Curiosity for AI and its potential to transform how software is built.
• Experience building AI products or developer tools.
• Familiarity with CRDTs, Tiptap/ProseMirror, or real-time collaboration.
• Strong design sensibility — you care how things feel, not just how they work.
