Thermal Test Systems Engineer, Energy Products

What To Expect

Tesla Energy’s Systems Engineering team is hiring a Thermals Test Systems Engineer to design and build thermal test rigs that replicate the cooling and heating architectures used in Megapack, Powerwall, and Supercharging products. You’ll own mechanical design for coolant-loop test stands, heat-exchange hardware, and structural assemblies, and work closely with Electrical, Controls, and Thermals teams to transform requirements into functional test equipment.

Strong fundamentals in fluid dynamics, thermal systems, and 3D CAD (CATIA preferred) are required.

• Design and build thermal test rigs that include coolant loops, heat exchangers, pumps, manifolds, flow-control, thermal loading, and other thermal-mechanical components
• Own CAD for all mechanical components and structural assemblies (80/20, sheet metal, machined parts)
• Integrate sensors, valves, actuators, instrumentation, and EE/Controls hardware
• Design and validate fluid circuits through prototyping, flow/pressure testing, and thermal loading
• Work with Controls and Thermals teams to translate system requirements into functional hardware
• Manage fabrication, vendors, BOMs, data acquisition, and technician handoff
• Ensure rigs are safe, maintainable, and updated as architecture evolves

• Degree in Mechanical Engineering, or equivalent experience
• 3+ years designing thermal/fluid systems (R&D, test equipment, HVAC, automotive, etc.)
• Strong 3D CAD skills (CATIA preferred)
• Strong fundamentals in heat transfer and fluid dynamics
• Hands-on prototyping: plumbing, fittings, manifolds, instrumentation, 80/20 builds
• Ability to execute builds, work with vendors, and manage BOMs in a fast-paced R&D environment
• Experience with high-power, electro-mechanical, and/or control systems preferred
• Familiarity with chillers, cold plates, expansion tanks, bleed/fill systems, and instrumentation preferred
• Familiarity with thermal modeling and CFD simulation preferred
• Prior experience working with environment test chambers preferred

• Medical plans - plan options with $0 payroll deduction
• Family-building, fertility, adoption and surrogacy benefits
• Dental (including orthodontic coverage) and vision plans, both have options with a $0 paycheck contribution
• Company Paid Health Savings Account (HSA) Contribution when enrolled in the High-Deductive 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, AD&D
• Short-term and long-term disability insurance (90 day waiting period)
• Employee Assistance Program
• Sick and Vacation time, 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

Expected Compensation

$112,000 - $210,000/annual salary + cash and stock awards + benefits
