Founding Engineer

Description

We're hiring a founding engineer who moves fast, cares about craft, and wants real ownership from day one. You'll build side by side with the founders, in person in London, from day one.

You should already use AI tools by default — pushing Cursor, Claude Code, Codex, and agent workflows hard, judging output critically, and moving faster without lowering the bar.

What you'll own

Build and ship core product features end to end. Talk to users constantly, find bottlenecks, and ship fixes fast. Suggest new features, new products, and new internal tooling. Help set the engineering bar, architecture, and pace of the company. This is not a role where you can coast. It requires deep ownership, agency, and responsibility.

Requirements

• Strong TypeScript and React skills.
• Roughly 1–5 years shipping real product software is a good baseline, but we'll flex for someone unusually strong.
• Ability to build full-stack product features with high autonomy.
• Strong product instincts and a bias toward outcomes.
• High agency: you notice problems, propose solutions, and drive things to completion.
• Good design taste. You can make sensible UI/product decisions, and Figma fluency is a plus.
• Clear communication and strong judgment.
• Comfort with ambiguity and a founder-speed environment.
• Heavy AI-tool usage as part of your real workflow, not as a novelty.
• Strong pluses
• Experience with Cloudflare Workers, Durable Objects, service bindings, realtime systems, or collaborative/live product surfaces.
• Experience building devtools.
• Experience building sandboxed or safety-sensitive systems.
• The company was founded by Dan, who dropped out of University College London and previously worked with the former CTO of Monzo at Iterate.com (http://Iterate.com).
• Experience: Any (new grads ok)
• Visa: Will sponsor
