About the Team
The Universes team within Research builds training environments for AI models to perform complex, long-horizon agentic tasks in ultra-realistic settings, teaching models to navigate ambiguity, handle interruptions, maintain context, and exercise judgment.
About the Role
Research Engineers build next-generation training environments for capable and safe agentic AI. This role blends research and engineering, implementing novel approaches, contributing to research direction, reinforcement learning, environment design, and capability evaluations.
Responsibilities
- Build the next generation of agentic environments
- Build rigorous evaluations that measure real capability
- Collaborate across research and infrastructure teams to ship environments into production training
- Debug and iterate rapidly across research and production ML stacks
- Contribute to research culture through technical discussions and collaborative problem-solving
You may be a good fit if you
- Are highly impact-driven — you care about outcomes, not activity
- Operate with high agency
- Have good research taste or senior technical experience, demonstrating good judgment in identifying what actually matters in complex problem spaces
- Can balance research exploration with engineering implementation
- Are passionate about the potential impact of AI and are committed to developing safe and beneficial systems
- Are comfortable with uncertainty and adapt quickly as the landscape shifts
- Have strong software engineering skills and can build robust infrastructure
- Enjoy pair programming (we love to pair!)
Strong candidates may also have
- Industry experience with large language model training, fine-tuning or evaluation
- Industry experience building RL environments, simulation systems, or large-scale ML infrastructure
- Senior experience in a relevant technical field even if transitioning domains
- Deep expertise in sandboxing, containerization, VM infrastructure, or distributed systems
- Published influential work in relevant ML areas
Logistics
Education requirements: At least a Bachelor's degree in a related field or equivalent experience.
Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.
