You'll build an operating system that runs service businesses with a workforce of AI agents, starting from nothing, and you'll own large parts of the product, architecture and infrastructure yourself. This is a CTO-calibre seat with meaningful equity. It suits someone who has already built something from nothing to production as a founder, co-founder, CTO or very early engineer. Depending on your strengths, you'll lean toward product and design-minded engineering, agent and LLM engineering, or full-stack, infra and scaling work, and in practice you'll touch all three. You'll work directly with a second-time founder who has a prior exit. There are no management layers and no backlog of tickets handed down to you.

The company has just closed a strong angel round from well-known European and US angels.
