Senior Mechanical Design Engineer — AI Model Training & Evaluation (Remote AI Evaluation Contract)

Join Jobtacular as a remote Senior Mechanical Design Engineer — AI Model Training & Evaluation (Remote AI Evaluation Contract) ($40 - $90/hour). We partner with leading AI research laboratories across major English-speaking markets to evaluate complex responses, design realistic domain scenarios, and calibrate next-generation foundation models using deep professional expertise in Design intent & assembly reasoning, Parametric modeling depth, Mechanism & kinematic sense, GD&T & tolerance judgment.

What You Will Do

• 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 model-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.
• Communicate findings and reasoning in clear, professional written and verbal form to support continuous project improvement.
• Demonstrated professional or academic background in Design intent & assembly reasoning, Parametric modeling depth, Mechanism & kinematic sense, GD&T & tolerance judgment, CAD tools expertise.

Who We Are Looking For

• Demonstrated experience in teaching, mentoring, or leading — whether through formal instruction, leading design reviews, or coaching engineering teams.
• Expertise in design intent, assembly reasoning, mechanism and kinematic analysis, and robust GD&T/tolerance judgment.
• Background in at least one discipline: industrial machinery and automation, robotics, automotive and heavy equipment, aerospace and defense, medical devices, consumer products, or tooling and fixture design.
• Exceptional written English communication skills — your documentation directly influences project deliverables.
• Bonus: Experience with FreeCAD, advanced GD&T/tolerance analysis, or formal design review leadership.
• Compensation Band: $40 - $90/hour
• Work Location: Remote (100% Remote / Asynchronous Flexibility)
