The work

As an LLM Code Evaluation Software Engineer, you will help create datasets used to train and test large language models. You will work with researchers and other teams to assess AI-generated code and improve the quality of coding solutions.

  • Curate code examples and create solutions in Python, JavaScript, ReactJS, C, C++, Java, Rust, and Go.
  • Review and improve AI-generated code for efficiency, scalability, reliability, and code quality.
  • Build verification agents and automated checks that find errors and assess software solutions.
  • Study parts of the software engineering cycle and evaluate model performance against industry benchmarks.
  • Work with cross-functional teams to improve AI coding solutions.
