Sr. Mechanical Design Engineer, Test Infrastructure & Systems Engineering

What to Expect

Tesla Energy's Test Infrastructure team is seeking a Mechanical Design Engineer to develop automated test equipment and mechanical infrastructure for energy storage, EV charging, and solar products. The role requires expertise in 3D modeling (CATIA), sheet metal design, prototyping, electromechanical packaging, 80 / 20 structures, mechanical component sourcing, and build oversight.

You will work closely with Electrical and Controls Engineers to integrate mechanical and electrical elements into robust test solutions. This includes bus bar fabrication, wire harness routing, bulkhead selection / mounting, enclosure design, and thermal management solutions (coolant loops, airflow, heat exchangers). The role involves both hands-on prototyping and design-for-manufacturing, as well as coordinating builds and outsourcing fabrication.

What You'll Do

• Design, develop, and maintain mechanical test infrastructure, including custom enclosures, thermal systems, electromechanical packaging, and automation rigs
• Own 3D modeling (CATIA preferred) for sheet metal, machined parts, 80 / 20 extrusions, and structural test setups
• Prototype and validate mechanical solutions, integrating bus bars, wire harnesses, and bulkhead penetrations for high-power electrical test systems
• Support harness routing, ensuring strain relief, serviceability, and proper mounting to align with EE design requirements
• Select and design bulkhead penetrations for high-voltage, coolant, and signal routing, ensuring compatibility with electrical and thermal constraints
• Oversee technician teams to support assembly, troubleshooting, and maintenance of mechanical test setups
• Manage outsourcing efforts, working with vendors and machine shops for custom mechanical and electrical hardware fabrication
• Optimize thermal management solutions, including coolant loops, heat exchangers, and airflow design for high-power test environments
• Work closely with cross-functional teams (EE, Controls, Firmware, etc.) to ensure seamless mechanical-electrical integration

What You'll Bring

Compensation and Benefits

Along with competitive pay, as a full-time Tesla employee, you are eligible for the following benefits at day 1 of hire :
