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).
