Job description

A well-backed, early-stage AI company is building an \"AI department\" for the everyday economy: mid-market accountants, lawyers, wealth managers and agencies who want to partner for their technology rather than build it themselves.

You embed inside customer businesses and ship the AI systems their teams run on, from infrastructure and pipelines through to orchestration and interface, taking each build from first prototype to production. You pair with a strategist who owns the customer relationship and the value case; the build is yours end to end.

What you'll own:

• The deployment build, taking a customer problem from first prototype to a production system their team relies on daily.
• The full stack, carrying cloud infrastructure, data pipelines, LLM orchestration and frontend yourself.
• The customer relationship, sitting with the people whose work you're changing, training them, owning the outcome.
• The feedback loop, carrying what worked back into the platform so the next deployment starts further ahead.

What we're looking for:

• Production grade infrastructure experience, having designed, built and operated systems at scale rather than just deployed them.
• Multiple 0 to 1 products shipped end to end, ideally as a founder or early engineer at a startup.
• Full stack capability across cloud, data, LLM orchestration and frontend.
• High agency, self directed, writing your own spec with no hand holding.
• Comfort being on site with customers and owning stakeholder relationships.

This isn't for you if you've only operated inside a big company, need a clearly defined spec before starting, or have only built demos with nothing shipped to production.

Founding equity attached. If you want to build the system the next hires run by rather than inherit someone else's roadmap, get in touch.
