• Set technical direction and establish engineering practices as the team grows.

• Ship improvements regularly to businesses using the product in recruiting and web agency services.

What We're Looking For

• At least 2 years of experience shipping production software, or an equivalent record as a founder, solo builder, or exceptional early-career engineer.

• Experience building and operating LLM or AI agent systems used by real customers.

• Strong full-stack range, with the ability to take work from backend and infrastructure through to the user interface.

• Experience scaling a working prototype into production infrastructure, and making technical decisions independently in an early-stage team.

• A track record of shipping frequently and explaining the difficult technical decisions behind your work.

• Founder experience or experience building agent orchestration, memory, evaluations, verification, or multi-agent workflows is valuable.
