Gearbox Test Engineer

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. Key Responsibilities Test Development & Execution

• 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.
Data Analysis & Validation
• 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.
Failure Investigation
• 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.
Test Facility & Rig Development
• 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.
Collaboration with Design & Simulation
• 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 motorsport, automotive, or aerospace experience preferred.
• Strong understanding of:
• Gear systems, tribology, and lubrication.
• Fatigue, wear mechanisms, and material behavior.
• 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.
Preferred Qualifications
• 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.
Key Performance Indicators (KPIs)
• 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).
