Job description

What to Expect

• Ownership: You'll have real responsibility from day one.
• High standards: We don't compromise on quality.
• Fast pace: We move quickly and expect you to keep up.
• Quantitative assessment: Your performance will be assessed on transparent criteria.

How you’ll contribute

We're looking for Staff or Senior Product Engineers to join our engineering team. We're a small team of generalists with deep experience in startups and a passion for craft. We move fast, ship often, and hold ourselves to a high bar. From day one, you’ll help shape the product’s direction and ship features to production within your first week. Requirements will be fuzzy – you’ll talk to users, form hypotheses, and iterate quickly to define what to build.

You may be a good fit if you

• Have worked at early‑stage startups and driven product direction
• Think in terms of user problems, not just technical solutions
• Have scaled TypeScript projects
• Enjoy refining and customizing your AI workflow into the early hours
• Build AI agents or LLM‑powered systems that go beyond simple prompting.

Who thrives here

We'd love to talk to you if you're relentless about self‑improvement and hold yourself to incredibly high standards, sweating the details others overlook. You see problems as solvable and find opportunity in challenges, energising the people around you in the process. You own outcomes, fixing problems rather than waiting for someone else to, and want to be measured on your impact. You're low ego and self‑critical, open to feedback, and give honest feedback directly and kindly.

We're building with

• A TypeScript monorepo, React, tRPC and Tailwind
• Inngest for background jobs and event‑driven workflows
• Deployed on Google Cloud Platform with Postgres

What we offer

• £100,000 - £150,000 depending on experience
• Meaningful early‑stage equity – you'll be an owner, not just an employee
• 5% employer pension contributions
• Comprehensive private medical cover including dental and optical
• 25 days holiday plus bank holidays
• Your choice in AI tooling

This role is based in Shoreditch, London and reports directly to the founder.
