Founding Agentic Engineer

ABOUT THE ROLE This is a founding-level engineering role at a gig economy / flexible staffing platform, sitting at the intersection of production AI systems and real-world labor marketplace operations. You'll own the entire agent layer end-to-end, working directly with the CTO to define how agentic systems get built, measured, and scaled — work that has genuine, production-grade consequences. WHAT YOU'LL DO - Design and own the agent layer holistically: context engineering, self-learning systems, evals, the agent harness, and the meta-harness used to build and evolve new agents. - Build a compounding knowledge base of undocumented systems so that each new integration is better than the last. - Develop self-healing workflows — agents that detect failures in production, diagnose root causes, and recover autonomously. - Set the engineering patterns and standards by which every agent at the company gets built, measured, and improved. - Help grow the agentic engineering team, with a path toward leading the people who own these systems. - Operate as a peer to the founding team and experiment relentlessly. WHAT WE'RE LOOKING FOR - 2–9 years of software engineering experience, with hands-on agentic software shipped within the last year. - Deep familiarity with harness-centric agent development: context engineering and eval-driven iteration are core to how you work. - Strong understanding of agent tracing and evaluation frameworks. - Implementation-focused mindset — you ship working systems in production, not research prototypes. - Proficiency in TypeScript; experience with Effect-TS, PostgreSQL, and LLM/agent tooling is a strong plus. - Background from high-caliber engineering organizations (e.g. large tech, professional services, or developer tooling companies). COMPENSATION & BENEFITS Salary range: $150,000 – $300,000 USD annually. Visa sponsorship is available. LOCATION On-site in San Francisco, CA, United States.
