About the job
Build post-training and evaluation systems for multimodal computer-use agents that handle browser, desktop, and cross-application workflows reliably.
What you'll do
- Create long-horizon computer-use environments from real workflows and prevent shortcuts, data leakage, and unsafe side effects.
- Train agents to recover from interface changes and failures, and evaluate task completion, efficiency, permissions, and escalation.
- Run post-training experiments, diagnose sources of performance changes, and deploy successful approaches.
What they ask for
- Relevant experience in multimodal agents, computer use, browser or desktop automation, RL, imitation learning, HCI, embodied agents, or long-horizon agent evaluation.
- Hands-on experience building and debugging model-training, post-training, agent, evaluation, or closely adjacent experimental loops.
- Strong experimental judgment and Python skills; ability to build reusable research and engineering artifacts.
- Comfort owning ambiguous problems and keeping partners and teammates informed.
Nice to have
- Publications, open-source systems, benchmarks, or shipped products demonstrating exceptional work.
