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. 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.
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.
- Communicate findings and reasoning in clear, professional written and verbal form to support continuous project improvement.
Nice to have
- 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.
Eligibility
- This is a fully remote position, open to candidates based in 55 countries, including United States, United Kingdom, Canada, Germany, India, France, Netherlands, Singapore.
