Founding Engineer

Founding Engineer

Build from Day Zero

London, Equity from day 1

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'll thrive here if

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.
