Applied Researcher - Computer Use
San Francisco. Posted 26 days ago
The role
You will build post-training and evaluation systems for multimodal agents operating browsers, desktops, and cross-application workflows. The work involves turning real workflows and traces into environments, rewards, and experiments.
What you will do
- Turn workflows into tasks, environments, evaluations, and reward signals
- Run post-training experiments against real baselines and deploy what works
- Build long-horizon computer-use environments from real workflows
- Train agents to recover from interface changes, partial failures, and ambiguous intermediate states
- Develop evaluations that distinguish genuine completion from plausible-looking behavior
- Own multimodal environments built from partner workflows, demonstrations, tools, interface state, and outcome criteria
- Own browser, desktop, and cross-application agents with reliable sandbox and boundary enforcement
- Own training and evaluation from demonstrations, interventions, production failures, synthetic tasks, and verifiable outcomes
- Own experiments on recovery and generalization across applications, layouts, permissions, and deployment contexts
- Work directly with customers, users, or research partners
Required qualifications
- Relevant experience: 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: meaningful baselines, careful trace inspection, clear failure attribution, and a willingness to change direction when the evidence changes
- Strong Python and the ability to build artifacts that other researchers and engineers can run, inspect, and extend
- Comfort owning ambiguous problems and keeping partners and teammates current as you resolve them
Nice to have
- Publications
- Open-source systems
- Benchmarks
- Shipped products
Benefits
- Cash Compensation Range of $150-300k + equity incentives
- Flexible Work (San Francisco, New York, London, or remote)
- Visa Sponsorship & relocation support
- Professional Development budget
- Team Off-sites & conference attendance
Before you apply
- Show something difficult you built, what failed, and how the evidence changed your approach
