About the Client
Our client is an early-stage AI startup in San Francisco, founded by alumni of Harvard and MIT. The company is in stealth. It is building an agent-based product that takes complex, high-stakes paperwork off the hands of US families: working out what applies to them, researching official sources, handling correspondence and following up over weeks, with every step checked and backed by evidence.
Parts of the product are already built and running in test. You will be the third person on the product and the first engineering hire, working directly with the two co-founders to take it into production with real users.

Why This Role Is Different: Product Ownership
This is not a ticket-taking role.



As the first hire alongside the founders, you will be expected to own the product, not just the code:
• Take whole parts of the system from design to production and be accountable for how they perform.
• Think about the user. The people using this product are going through a hard time, so the quality of every screen, message and automated action matters.
• Weigh trade-offs, push back on ideas, and help decide what to build next.
• Work on your own for hours at a time, and leave clear updates on what shipped, what is blocked and what needs a decision.
• Help set the engineering standards and practices as the team grows.

What You'll Work On
This is a broad role across the whole product:
• Agents and the agent harness: build and test agents that call tools in bounded loops, with budgets, stop conditions, failure handling and checks on every output.
• Model layer: call models from several vendors, route between them and fa
