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 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
• Communicate 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 drawings
• Mastery 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 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
