Build from Day Zero in London, with equity from day one. You’ve built things from scratch. Now build the thing. This is your chance to become the first engineer at a well-funded AI start-up on a mission to reinvent how accountants work with Excel, automating painful workflows with no-code tools and AI smarts. It’s early, it’s raw, and it’s all to play for.
You’ll work directly with two experienced founders, shape the product and engineering culture, and ship fast. There’s real capital behind this (multi-million seed round from a top-tier VC), but zero corporate baggage.
Why this one’s different:- True blank canvas
- Your fingerprints will be all over the codebase, product and tech stack
- Equity worth caring about
- Take real ownership in the company from day one
- Clear track to CTO or Head of Engineering if that’s more your path
- No LLM hype machine — just practical, user-first AI applied to real problems
- You’re fluent in TypeScript + Next.js, and you’ve shipped real product at pace
- You’ve worked in start-ups or fast-moving tech teams
- You think like a builder, not just an engineer — product-focused, high agency, always shipping
- You’re excited by ambiguity and want to help define not just what gets built, but why
Location and setup: Hybrid from London, minimum 3 days per week in the office. Must have the right to work in the UK.
Package: £100k – £160k depending on experience. Equity on the table — more skin in the game, more upside. MacBook, private medical, dinners and Ubers when working late.
This isn’t a job. It’s a shot at being the one who built it all. Curious to learn more? Drop your CV or just reach out — let’s chat.
