Mechanical Design Engineer for AI Training

Apply production mechanical design expertise to help improve AI systems that interpret, solve, and explain complex engineering challenges. This remote contract role centers on high-quality technical input across GD&T, tolerance stack-up, design for manufacturability, and drawing release. No prior AI experience is required. Key Responsibilities Evaluate and solve advanced mechanical design and CAD problems involving part and assembly design, GD&T, tolerance stack-up, and design for manufacturability. Review AI-generated technical responses for correctness, accuracy, and engineering quality. Apply practical engineering judgment to production design scenarios and theoretical questions. Analyze and troubleshoot design issues using tolerance stack-up analysis, GD&T per ASME Y14.5, and design-for-manufacturability and assembly reviews. Provide domain expertise and clear written and verbal feedback to strengthen AI reasoning and performance. Collaborate remotely with distributed experts and project participants. Qualifications Mechanical design and CAD expertise, with at least 5 years of experience in production design roles and direct ownership of designs through GD&T, tolerance stacks, DFM, and drawing release. BS or MS in Mechanical Engineering, Aerospace, or Industrial Design. CSWP or CSWE certification is a plus. Expert knowledge of parametric CAD modeling, GD&T per ASME Y14.5, tolerance stack-up analysis, and design-for-manufacturability and assembly principles. Demonstrated ability to take designs from concept through detail drawings, ECR/ECN, and production release. Familiarity with ASME Y14.5, ASME B89 dimensional metrology, and manufacturing constraints for machining, sheet metal, injection molding, and casting. Professional English proficiency and exceptional written and verbal communication skills. Experience with SolidWorks, Creo, NX, CATIA, or Inventor, PLM/PDM systems, or CAM/CNC programming is a plus. Strong preference for evidence of rigorous problem authoring, such as service on an olympiad problem committee, textbook problem-set or solutions-manual authorship, NCEES or academic qualifying-exam item writing, standards committee service, leadership or top placement in engineering design competitions, or an early-career fellowship or grant. Work Terms Remote contract engagement. Compensation $60 to $130 per hour.
