About the role
About the Role
Join an early-stage AI company as its first engineering hire, working directly with the founder in San Francisco. You will evolve a working AI workforce product into reliable infrastructure designed to scale, with the opportunity to grow into a CTO role as the work and team develop.
What You'll Do
* Rebuild the product foundation to support substantial user growth and production workloads.
* Design and operate the agent runtime, including orchestration, memory, verification, and reliability systems.
* Own technical work across backend, infrastructure, frontend, and agent systems, as company needs evolve.
* Set the technical architecture, stack, engineering standards, and development practices.
* Ship improvements weekly to customers using the product in live service businesses.
What We're Looking For
* At least two years shipping production software, or an equivalent record as a founder or solo builder; exceptional early-career engineers are also considered.
* 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.
Compensation & Benefits
Base salary is $150,000 to $250,000 USD annually, plus meaningful founding equity. Visa sponsorship and relocation support are available.
