Job summary

GM Performance Power Units is seeking a Gearbox Test Engineer to lead development, validation, and reliability testing for F1 transmission systems within a factory setting. You will run full dyno tests, develop rigs, and drive data-driven improvements to ensure durability under extreme conditions.

You will analyze high-resolution test data, correlate results with simulations, and collaborate with design teams to optimize gear systems, lubrication strategies, and materials.

Qualifications

• Bachelor's or Master's degree in Mechanical Engineering, Automotive Engineering, a related discipline or equivalent experience.
• 3+ years in mechanical testing with motorsport, automotive, or aerospace experience preferred.
• Experience with test rig operation and instrumentation including torque, speed, strain, and temperature measurements

Responsibilities

• Plan, develop, and execute rigorous test programs for gearbox systems, including full transmission dyno testing, sub-system and component-level validation, and endurance and accelerated life testing.
• Define test procedures, instrumentation requirements, and acceptance criteria.
• Operate and support advanced test rigs simulating real-world race duty cycles.
• Analyze high-resolution test data to assess gear durability, fatigue life, friction losses, efficiency, thermal performance, and oil system behavior.
• Correlate test data with simulation models and historical track data.
• Produce clear engineering reports with recommendations for design and performance improvements.
• Lead root cause analysis of gearbox and component failures.
• Work with materials, design, and manufacturing teams to implement corrective actions.
• Maintain failure databases and support reliability growth programs.
• Support the specification, development, and commissioning of new test rigs and instrumentation systems.
• Improve existing test capabilities, automation, and data acquisition processes.
• Ensure test systems replicate real-world operating conditions as accurately as possible.
• Work closely with design engineering teams to validate new gearbox concepts and updates.
• Provide feedback on gear design, materials, coatings, and lubrication strategies.
• Support validation of simulation tools and models used for gearbox performance prediction.
