This generalist role centers on building server-side product features and language-model-powered services, from early problem definition through to live release. The engineer makes technical choices with minimal supervision and partners with the founding group on product direction and customer needs.\nWhat you'll do\n- Carry features from initial problem definition through server-side build-out and into live use.\n- Build and release language-model-driven agents that handle large volumes of imperfect data and behave consistently.\n- Set the course for how systems are structured, how data is organized and how interfaces are built, and hold code to a high bar.\n- Take charge of projects where both the risk and the reward are significant, with little supervision.\n- Help determine product direction with the founding group and translate customer requirements into engineering plans.\n- Partner with the founding group on account work as customer deployments expand.\nRequirements\nWhat we're looking for\n- Five-plus years of server-side engineering, including work on products that customers use directly.\n- Prior work as a founder or early-hire engineer at a young company that launched and grew within the past five years.\n- A history of clear business results that the candidate drove personally, rather than a list of assigned duties.\n- Hands-on ownership of product functionality from concept through release, with direct contact with end users and no product manager intermediating.\n- Skill in clarifying murky problems and working from fundamentals before proposing a design.\n- Experience defining the technical course for unclear, consequential initiatives.\n- Versatile engineer who is at ease working across many layers of a product, not only low-level plumbing.\n- Advanced command of Python for server software running in production.\n- Sound judgment in structuring server-side software and designing how its parts interact.\n- Comfortable designing interfaces between services and working with SQL-based databases.\n- Practical history creating software on top of language models or autonomous agent frameworks.\nBenefits\nCompensation and benefits\n- Base salary: USD 190,000 to 300,000 per year\n- Equity\n- Health, dental and vision coverage\n- Flexible time off\nLocation and work model\n- Remote (US)\n- Full-time
