We design and scale simulation environments where agents learn to operate safely and autonomously. We work with the world’s leading model labs to push the frontier of agent capabilities. We've raised >$8M from Base10, Cervin Ventures, Founders Future, Y Combinator, and other incredible investors & angels.\nAbout the role\nWe’re hiring a Founding Member of Technical Staff - Engineering to build the systems that power our RL and contributor platforms. You’ll be a member of the founding team and should expect to wear multiple hats. While this role is engineering-leaning, we’re looking for people who are energized by hard technical problems and excited to operate at the intersection between engineering, research, and product. Examples of projects you could work on include:\nDeveloping platforms that allow contributors to create RL environments\n\nDesigning QA agents to ensure data quality\n\nTooling to improve environment and task creation processes\n\nYou’ll be a good fit if you:\nHave strong engineering fundamentals and are a prolific user of AI tools\n\nHave experience with full-stack product development\n\nHave experience with infrastructure, containerization, networking, and distributed systems\n\nHave an interest in reinforcement learning environments\n\nPerks:\nComprehensive health, dental, and vision insurance\n\nFree meals with the team\n\nFree Bay Club membership (right next door to our Embarcadero office!)\n\nCommuter benefits\n\n401(k)\n\nUnlimited PTO\n\nTop of the line tech\n\nFrequent team activities and outings\n\nCulture:\nPolymath is a team of researchers, engineers, and operators focused on advancing the frontier of safe, superintelligent AI agents.\n\nWe have a flat organizational structure. We believe that people do their best work when they’re self-motivated and driven by a desire to learn, contribute to the team’s goals, and advance scientific progress.\n\nWe’re looking for folks who ship fast, set high standards for themselves, and are great team players.
