Power Module Mechanical Design Engineer

About the role

Join the electric revolution as a Mechanical Design Engineer. You'll lead module packaging design end-to-end, from first-principles concept to high-volume production, shaping the technology that powers every vehicle and energy product we ship. Working at the intersection of thermal, mechanical, and electrical engineering, you'll partner with cross-functional teams to push the limits of efficiency, reliability, and scale. Your designs won't just hit a spec sheet, they'll drive the future of sustainable energy, and we're looking for a bold, motivated engineer ready to lead the way.

Responsibilities

• Own mechanical design and optimization of power modules, balancing thermal, mechanical, electrical, and manufacturing constraints
• Develop packaging solutions with cross-functional teams from requirements through design, validation, and production builds
• Research and introduce new packaging materials and processes (substrates, attaches, encapsulants, interconnects, and beyond)
• Create, release, and control package drawings and design documentation
• Lead or contribute to DFMEA/PFMEA and resolve packaging and assembly issues through root-cause analysis
• Support mechanical tooling design for assembly equipment as designs move into production
• Take modules from prototype through high-volume manufacturing, applying direct experience with SiC or GaN power modules and automotive power electronics / traction inverter packaging where relevant

Requirements

• Bachelor’s Degree in Mechanical Engineering or equivalent experience
• Master's Degree or Doctorate Degree preferred for candidates with deep packaging or multi-physics backgrounds
• 3+ years of industry experience in power module, power electronics packaging, or closely related semiconductor packaging design
• First-principles mindset across thermal, mechanical, materials, and electrical interactions
• Strong CAD skills (SolidWorks, CATIA, or similar) and experience with FEA / multi-physics simulation (ANSYS Mechanical, ICEPAK, Q3D, or equivalent)
• Working knowledge of DFM, DFT, design for reliability, tolerance analysis, and DFMEA/PFMEA
• Familiarity with automotive reliability, environmental, and safety standards
• Hands-on knowledge of electronics packaging materials and processes: ceramics/substrates, solder or sinter attaches, encapsulation, wire bonding, adhesives, copper clip, etc.

Benefits

• Medical plans with plan options including $0 payroll deduction
• Family-building, fertility, adoption, and surrogacy benefits
• Dental (including orthodontic coverage) and vision plans, both with options for $0 paycheck contribution
• Company-paid Health Savings Accounts (HSA) contribution when enrolled in the High-Deductible medical plan with HSA
• Healthcare and Dependent Care Flexible Spending Accounts (FSA)
• 401(k) with employer match, Employee Stock Purchase Plans, and other financial benefits
• Company-paid Basic Life and AD&D insurance
• Short-term and long-term disability insurance (90-day waiting period)
• Employee Assistance Program
• Sick and Vacation time (Flex time for salary positions, accrued hours for hourly positions), and Paid Holidays
• Back-up childcare and parenting support resources
• Voluntary benefits including critical illness, hospital indemnity, accident insurance, theft & legal services, and pet insurance
• Weight Loss and Tobacco Cessation Programs
• Tesla Babies program
• Commuter benefits
• Employee discounts and perks program

Pay

Expected compensation: $91,600 - $316,800/annual salary + cash and stock awards + benefits. Pay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience.
