Member of Technical Staff - Research

About the role

We’re hiring a Founding Member of Technical Staff - Research to help advance the frontier of autonomous agents. You’ll work on core research problems in long-horizon evaluation, agent post-training, and environment design, with a focus on understanding where current models fail and how to improve them.

As a member of the founding team, you should expect to wear multiple hats: building benchmarks, creating environments, writing production code, and running rigorous experiments. We’re looking for people who are excited by hard open-ended problems and want to operate at the intersection of research and engineering. Examples of projects you could work on include:

• Investigating failure modes of frontier models
• Creating rigorous benchmarks that evaluate how well frontier agents perform on complex, realistic tasks requiring long-horizon reasoning and tool use in dynamic environments
• Post-training agents that can reason, plan, and act over extended time horizons
• Publishing research

You’ll be a good fit if you

• Have strong engineering & research fundamentals and are a prolific user of AI tools
• Have experience post-training frontier models
• Have experience shipping reliable, production-quality code
• Have a track record of publications

Perks

• Comprehensive health, dental, and vision insurance
• Free meals with the team
• Free Bay Club membership (right next door to our Embarcadero office!)
• Commuter benefits
• 401(k)
• Unlimited PTO
• Top of the line tech
• Frequent team activities and outings

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. You’ll be a member of our founding team: have fun, learn a lot, and do high-impact work alongside great people.
