What We're Looking For

• Full-stack range, with the ability to work from backend and infrastructure through product UI.
• Experience building and operating LLM or AI agent systems used by real customers, not demo-only projects.
• Experience turning prototypes into production infrastructure, including architecture, data models, runtimes, and orchestration.
• Evidence of owning technical decisions in a small or early-stage team, and shipping to production users weekly or faster.
• Useful experience includes agent orchestration, memory, evaluations, verification, multi-agent workflows, or software for recruiting, agencies, and other service businesses.
• Strong technical fundamentals and the ability to explain the difficult parts of systems you have built.
