  • Evaluate AI-generated solutions for correctness, assumptions, and engineering logic.
  • Validate analytical or numerical results using Python (NumPy, SciPy, Pandas).
  • Improve AI reasoning to align with first principles and accepted engineering standards.
  • Apply structured scoring criteria to assess multi-step problem solving.

What we look for

This opportunity is a good fit for mechanical engineers with an experience in python open to part-time, non-permanent projects. Ideally, contributors will have: 

  • Degree in Mechanical Engineering or related fields, e.g. Thermodynamics, Fluid Mechanics, Mechanical Design, Computational Mechanics, etc.
  • 3+ years of professional mechanical engineering experience
  • Strong written English (C1/C2)
  • Strong Python proficiency for numerical validation
  • Stable internet connection 

Professional certifications (e.g., PE, CEng, PMP) and experience in international or applied projects are an advantage.

How it works

Apply → Pass qualification(s) → Join a project → Complete tasks → Get paid

Project time expectations

For this project, tasks are estimated to require around 10–20 hours per week during active phases, based on project requirements. This is an estimate, not a guaranteed workload, and applies only while the project is active.

Payment

  • Paid contributions, with rates up to $40/hour* 
  • Fixed project rate or individual rates, depending on the project
  • Some projects include incentive payments

*Note: Rates vary based on expertise, skills assessment, location, project needs, and other factors. Higher rates may be offered to highly specialized experts. Lower rates may apply during onboarding or non-core project phases. Payment details are shared per project.
