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).
