Founding Member of Technical Staff — RL

About Naive

Naive is building autonomous companies: agent systems capable of operating real businesses end to end.

We release autonomous company templates and benchmarks, alongside a studio—where users can deploy and operate these systems. Our infrastructure platform, Vetta, powers long-running, high-volume agent workloads.

We’ve raised $28.5M from Nexus Venture Partners, Y Combinator, Zetta Venture Partners, Liquid 2 and leading operators.

The Role

Build real-world agent environments, benchmarks and autonomous company blueprints—and make Vetta the best-performing agent within them. Accordingly, as a founding MTS member, you have the chance to earn significant equity in a fast growing Series A company.

What You’ll Do

• Turn complex business workflows into reproducible agent environments • Design tasks, rewards, evals and benchmarks that measure real outcomes • Build production-ready autonomous company blueprints • Run experiments, analyze failures and improve agent performance • Develop training data and optimization loops from agent trajectories • Publish credible benchmarks, technical reports and demos

Must-Haves

• Strong Python and research-engineering ability • Experience building agents, evals or RL environments • Deep understanding of tool use, long-horizon tasks and LLM failure modes • Ability to design rigorous experiments and ship production systems • High agency and comfort working on ambiguous 0→1 problems

Nice-to-Haves

• RL or post-training experience • Browser, coding or computer-use agent experience • Experience publishing benchmarks or technical research • Familiarity with distributed agent infrastructure
