  • Improve source code documentation and identify technical debt and high-risk code.
  • Support scientific data-processing workflows and a range of conceptual, process, and numerical models.

Required qualifications:

  • Master's degree in computer science, engineering, or a related discipline such as environmental science, mathematics, or physics; or a related bachelor's degree with at least 10 years of relevant experience.
  • At least 5 years of experience in computational modeling, software development, and software documentation, including legacy software and systems.
