About the Role
Join the engineering team as a founding-level engineer responsible for the agent layer at a flexible-work marketplace and SaaS company. You will build production agent systems that connect with real-world business workflows, set patterns for how agents are built and improved, and work closely with company leadership.
What You'll Do
-
Own the agent layer end to end, including context systems, self-learning, evaluations, the agent harness, and the meta-harness.
-
Build a knowledge base that accumulates information about undocumented systems and improves future integrations.
-
Develop workflows that detect production failures, diagnose causes, and recover autonomously.
-
Establish how agents are built, measured, and improved across the platform.
-
Create tools and processes that enable teams to build, evaluate, and evolve agents quickly.
-
Help grow the team and take on increasing leadership of agentic systems.
What We're Looking For
-
Two to nine years of professional software engineering experience, with a degree completed or in progress in engineering, computer science, or a quantitative field.
-
Recent experience building and shipping agentic software in production, ideally in an early-stage startup environment.
-
Strong experience with context engineering, evaluation-driven iteration, agent tracing, and production agent harnesses.
-
Experience building systems that learn from accumulated knowledge or autonomously detect, diagnose, and recover from failures.
-
Familiarity with TypeScript, Effect-TS, PostgreSQL, large language models, and agent evaluation tools.
