The work

You will turn mathematical proofs and dense academic material into structured software systems, automated pipelines, and reusable tools for AI agents. The work combines mathematical reasoning with hands-on engineering and system evaluation.

You will work with mathematical researchers and other STEM experts to turn abstract ideas into modular, reliable software. You will also review agent outputs and execution traces, then improve the systems based on what you find.

  • Design, build, and optimize multi-step agent workflows for multi-hop reasoning, hypothesis generation, and technical validation.
  • Translate mathematical proofs and other complex academic material into technical specifications and automated pipelines.
  • Develop architecture frameworks, tools, and memory systems for STEM-focused AI agents.
  • Evaluate agent performance for accuracy, reliability, and traceability across complex execution steps.
  • Collaborate with mathematical researchers and subject-matter experts on reusable AI workflows.
