Scale AI is hiring a Staff Software Engineer, RL Environments, on-site in San Francisco or New York. The work covers both the platform for building, running and verifying reinforcement-learning environments at scale — sandboxed execution, environment packaging and versioning, rollout orchestration, trajectory capture, verifier frameworks — and the environments themselves: task suites and graders that hold up under adversarial optimization. The posting asks for eight or more years of engineering experience, strong Python, distributed systems and containerization depth, and hands-on LLM work with agent loops, tool calling or eval harnesses.
