Job Description
Founding Software Engineer | Full-Time | London (King's Cross) | £60K - £100K+ + Equity
I'm working with a YC-backed AI start-up hiring for their second Software Engineer, an opportunity for someone who loves to build.
They're building an intelligence platform for consumer brands. Sitting between infrastructure and AI - they're pulling data and turning it into decisions brands can act on immediately.
The founding team has serious pedigree. Previously built and exited companies, worked at top-tier financial institutions, and have been in the trenches of AI product development since before it was fashionable. They're technical, close to their customers, and want an engineer who
operates the same way.
