About Polymath Polymath is an applied research lab focused on advancing long-horizon agent capabilities through reinforcement learning. 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. Polymath is backed by Base10, Founders Future, Y Combinator, and other incredible investors & angels. We've raised an $8M seed, and are growing out the team. About the role We’re looking for talented researchers currently enrolled in MS / PhD programs to collaborate on a research project focused around frontier benchmarks and environments for long-horizon AI agents. This will require 1) identifying failure modes in frontier models, 2) developing rigorous benchmarks that evaluate how well frontier agents perform on complex, realistic tasks requiring long-horizon reasoning and tool use in dynamic environments, and 3) training autonomous agents that can reason, plan, and act over extended time horizons. We can accommodate full-time or part-time engagements. The goal of the residency is to culminate in a publication, and if there is a mutual fit, transition into a full-time role. If you’re interested in joining Polymath but are not currently a student, please apply to the Member of Technical Staff role. You’ll be a good fit if you: Are currently pursuing an MS or PhD program in Computer Science or a related field Have experience with reinforcement learning, benchmarking frontier models, or model post-training Have experience with systems engineering and can write production-quality code Have a strong track record of publications Have high agency, move quickly, and enjoy working on open-ended research problems Culture Polymath is a team of researchers, engineers, and operators focused on advancing the frontier of safe, superintelligent AI agents. We 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. We’re looking for folks who ship fast, set high standards for themselves, and are great team players.
