The work

This role focuses on evaluating how AI models handle expert-level security problems. It is research and assessment work, not production engineering.

You will create realistic security scenarios, write reference solutions and grading rubrics, assess AI-generated answers, and explain your feedback clearly.

  • Design technical problem sets focused on cryptanalysis and reverse engineering.
  • Write expert reference solutions and rubrics based on security best practices.
  • Rate AI-generated outputs for correctness, depth, and sound technical judgment.
  • Provide structured feedback and clear explanations to support model improvement.

What it pays and takes

This is a remote, part-time contractor role for experienced security professionals. You should be able to work independently and asynchronously.

  • Pay: $135 per hour.
  • Time: 20 or more hours per week.
  • Work setup: Fully remote and asynchronous.
  • Location: Open to candidates in the countries listed for this role.
  • Language: Fluent English.
  • Experience: Currently or recently active in security, with hands-on cryptanalysis or reverse engineering experience.
  • Professional background: 6 to 10 years of relevant experience.
  • Education: A bachelor's degree in a related field is required; a master's degree is strongly preferred.
  • Communication: Strong written skills for technical explanations and structured feedback.
  • Helpful experience: Security research publications, open-source contributions, recognized security work, peer review, code review, grading, editing, reverse engineering, cryptanalysis, or CTFs.
