About the Role

This is a founding-level engineering role at an agentic integration platform serving the real economy. The company's agents perform real work with real consequences inside production systems — think shift-based staffing, logistics, and flexible labor markets. You will own the agent layer end-to-end, working directly with the CTO as a peer from day one. This is a rare opportunity to build production-scale agentic systems at a moment when very few teams have shipped them.

What You'll Build

• A context and self-learning system: A compounding knowledge base of undocumented integrations, so that connecting the 1,000th company is dramatically better than connecting the first.
• Self-healing workflows: Agents that autonomously detect, diagnose, and recover from production failures without human intervention.
• A meta-harness: The runtime harness that agents execute on, plus the tooling layer that enables the team to build, evaluate, and ship new agents in days.

What You'll Do

• Own the full agent layer: context engineering, self-learning, evals, harness architecture, and meta-harness design.
• Set the patterns and standards for how every agent at the company is built, measured, and continuously improved.
• Experiment relentlessly alongside founders and help shape the technical direction of the product.
• Contribute to hiring and eventually grow into leading the team responsible for agentic systems.

What We're Looking For

Required:

• Hands-on experience building agentic software within the last year — this field moves fast and recency matters.
• Deep familiarity with harness-centric agent development: context engineering and eval-driven iteration.
• Strong understanding of agent tracing and evaluation frameworks.
• An implementation-first mindset — you ship working systems in production, not research prototypes.
• Comfort with the tech stack: TypeScript, Effect-TS, PostgreSQL, and LLMs / agent frameworks.

Nice to Have:

• Prior experience at a high-caliber engineering organization (e.g., large tech, top-tier consulting, or developer tooling).
• Background working on integration platforms, workflow automation, or marketplace infrastructure.

Compensation & Benefits

• Salary: $150,000 – $300,000 USD annually, depending on experience.
• Founding engineer equity participation.
• Visa sponsorship is available.
