Senior Mechanical Design Engineer

Senior Mechanical Design Engineer [$40 - $90/hour] Role Responsibilities Analyze and dissect multi-part mechanical assemblies to identify critical design decisions, constraints, and potential failure points that challenge expert reasoningFormulate challenging, non-obvious technical questions that test real-world mechanical design judgment, ensuring relevance and difficulty beyond junior-level understandingValidate and document defensible, exact answers directly from CAD models, ensuring clear traceability and accuracyReview AI-generated outputs, pinpoint breakdowns or inaccuracies in mechanical reasoning, and suggest targeted improvementsFlag ambiguous, trivial, or unanswerable questions, refining or sharpening them for clarity and precisionThoroughly document edge cases and sources of disagreement within answers to maintain strict verifiabilityCommunicate findings and reasoning in clear, professional written and verbal form to support continuous project improvement Good Candidature 5+ years of professional experience creating and overseeing multi-part mechanical assemblies from concept, not just from existing drawingsMastery in at least one major parametric CAD tool (SolidWorks, Creo, NX, CATIA, Inventor, Fusion, Onshape, or Solid Edge)Demonstrated experience in teaching, mentoring, or leading whether through formal instruction, leading design reviews, or coaching engineering teamsExpertise in design intent, assembly reasoning, mechanism and kinematic analysis, and robust GD&T/tolerance judgmentBackground 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 designExceptional written English communication skills your documentation directly influences project deliverablesBonus: Experience with FreeCAD, advanced GD&T/tolerance analysis, or formal design review leadership
