You will own the infrastructure end-to-end, creating a local-first, encrypted system that lets AI learn and compound context for users. This is a rare opportunity to rebuild an engine from the ground up and transition into a co-founder role at a high-growth startup.
Founding Engineer at VC-backed consumer AI startup
AI knows everything about the world, but nothing about the user. This stealth VC-backed startup is building the personal memory layer for AI, and they need a Founding Engineer to own the engine. With a package of £160k and up to 5% equity, you'll rebuild their core infrastructure from scratch, with a clear written path to a Co-founder title. If you’re a Go expert who obsesses over performance, privacy-first architecture, and shipping at lightning speed, this is your seat at the table. Join a team with a track record of scaling global consumer brands.
