Job Summary

Mindrift offers remote, project-based opportunities for mechanical engineers to contribute to the development and evaluation of advanced AI systems for leading technology companies. Participants engage in tasks such as designing graduate-level engineering problems, validating AI-generated solutions, and providing analytical checks using Python. Engagements are on a flexible, non-permanent basis, requiring an estimated 10–20 hours per week during active project phases, with compensation up to $40/hour based on expertise, project, and assessment results.

Ideal candidates have a degree in Mechanical Engineering or a related field, at least three years of professional experience, and advanced written English proficiency (C1/C2). Strong skills in Python (especially libraries like NumPy, SciPy, and Pandas) are essential. Professional certifications and experience in international or applied projects are advantageous. Reliable internet is required.

This is not permanent employment, and workload may vary with project activity. Payment structure, including incentive opportunities, is clarified per project. Applicants should submit their CV in English with a self-assessed English level.
