Gearbox Test Engineer

Job Summary

GM Performance Power Units - Concord, NC
Gearbox Test Engineer - Onsite

The Gearbox Test Engineer is responsible for the development, validation, and reliability testing of Formula 1 transmission systems within a factory environment. This role focuses on dyno testing, rig development, and data-driven engineering to ensure gearbox performance and durability meet the extreme demands of Formula 1 competition. Working closely with design and performance groups, the engineer will lead structured test programs to validate new designs, investigate failures, and drive continuous performance improvements—all without trackside 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.

• Bachelor’s or Master’s degree in Mechanical Engineering, Automotive Engineering, a related discipline or equivalent experience.
• 3+ years in mechanical testing with motor sport, automotive, or aerospace experience preferred.
• Strong understanding of gear systems, tribology, and lubrication.
• Strong understanding of fatigue, wear mechanisms, and material behavior.
• Strong understanding of thermal and mechanical loading in high-speed rotating systems.
• Experience with test rig operation and instrumentation including torque, speed, strain, and temperature measurements.
• Proficiency in data analysis tools (MATLAB, Python, or similar).
• Familiarity with DAQ systems and automated test environments.
• Understanding of simulation correlation (FEA, multibody, or drivetrain models) is beneficial.
• Strong analytical thinking and problem-solving skills.
• Detail-oriented with a structured engineering approach.
• Effective communicator across cross-functional teams.
• Ability to manage multiple test programs simultaneously in a fast-paced environment.

• Experience with transmission systems, rotating machinery, or powertrain components preferred.
• Experience in a high-performance or R&D testing environment is highly desirable.

• Primarily factory-based role with no routine travel required.
• Hands-on involvement with test rigs and mechanical systems.
• May require flexible hours to support intensive test programs.

• Test program delivery (timing, quality, and completeness).
• Correlation accuracy between test data and simulation.
• Reduction in gearbox failure rates and reliability issues.
• Contribution to performance improvements (efficiency, durability, weight).

• Bonus scheme
• Private healthcare
• 401(k) plan including company match
• Employer-paid life insurance and disability coverage
• 32 days annual leave (including holidays)
• Free financial advisor access
• Employee Assistance Programs (EAP)
• Subsidized on-site dining
• On-site gym
• Discounted GM vehicle purchase/lease program
• Free on-site EV charging for personal GM vehicles
