Senior Research Engineer

Lead the design and development of RL environments used by frontier labs to train next-generation model capabilities. You'll architect systems that directly shape how the world's most advanced AI models learn and improve.

Research Engineer

Build and design environments used by frontier labs to train state-of-the-art capabilities into models. Work on cutting-edge infrastructure that enables breakthrough AI capabilities.

Infrastructure Engineer

Build and scale the compute infrastructure that powers our RL training environments. Design reliable, high-throughput systems for orchestrating thousands of concurrent environment instances across cloud providers.

Full Stack Engineer

Own the end-to-end developer experience for our platform — from the dashboards researchers use to monitor training runs, to the APIs that integrate with frontier lab workflows. Ship product that real users depend on daily.

ML Engineer

Develop and refine the reward models and evaluation frameworks that determine how effectively our environments train AI capabilities. Partner with frontier labs to design benchmarks that meaningfully measure model progress.

Research Scientist — Benchmarks

Design rigorous benchmarks that expose real capability gaps in frontier models. Collaborate with domain experts to translate professional workflows into measurable evaluation criteria used industry-wide.

Market Research Lead

Collaborate with experts across medical, financial, and engineering sectors to research and understand current capability gaps in AI models. Identify how these gaps lead to lower adoption rates and key risks for AI companies.

Technical Program Manager

Coordinate complex, cross-functional projects between our engineering team, domain experts, and frontier lab partners. Keep high-stakes deliverables on track in a fast-paced environment where the work directly shapes AI progress.

Data Operations Lead

Build and manage the pipelines and processes that turn raw domain expertise into high-quality training data. Scale our data partner network and ensure the datasets powering frontier model training meet rigorous quality standards.
