Senior Software Engineer, Reinforcement Learning

The work

You will create reproducible reinforcement learning environments that test how AI models solve complex software engineering workflows. Your work will cover DevOps, CI/CD, debugging, and command-line tools such as Git, Docker, GDB, AddressSanitizer, and FFmpeg.

You will also create realistic software engineering scenarios, produce golden reference solutions that show reliable ways to complete tasks, and assess solutions using sound judgment about algorithms, data structures, maintainability, performance, and scalability.

• Design tasks that evaluate AI models on DevOps, CI/CD, and debugging problems.
• Build or refine reproducible reinforcement learning environments and realistic software workflows.
• Use command-line development and debugging tools, including Git, Docker, GDB, AddressSanitizer, and FFmpeg.
• Create golden reference solutions for the workflows and tasks you develop.

About AI training work

AI training is the human work behind systems that learn from examples, including software tasks, model responses, and evaluations. People with strong technical expertise help define reliable examples and judge whether AI systems solve difficult problems correctly.
