Senior Mechanical Design Engineer | Remote - Contract

Role Title: Senior Mechanical Design Engineer Role Type: Contractor (~15hrs/week) Location: Remote We are engaging Senior Mechanical Design Engineers to contribute to a customer's project involving complex CAD assembly exploration and AI advancement. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters. Required Skills Design intent & assembly reasoning Parametric modeling depth Mechanism & kinematic sense GD&T & tolerance judgment CAD tools expertise Scope of Work Analyze and dissect multi-part mechanical assemblies to identify critical design decisions, constraints, and potential failure points that challenge expert reasoning. Formulate challenging, non-obvious technical questions that test real-world mechanical design judgment, ensuring relevance and difficulty beyond junior-level understanding. Validate and document defensible, exact answers directly from CAD models, ensuring clear traceability and accuracy. Review AI-generated outputs, pinpoint breakdowns or inaccuracies in mechanical reasoning, and suggest targeted improvements. Flag ambiguous, trivial, or unanswerable questions, refining or sharpening them for clarity and precision. Thoroughly document edge cases and sources of disagreement within answers to maintain strict verifiability. Communicat
