Test and Validation Engineer – Gear and Differential Systems chez Johnson Electric

Come Innovate Motion with Us

As a Test & Validation Engineer, you will be part of a newly formed Gear & Differential Systems team driving forward exciting and strategically important projects in the field of e-drive technologies. This is a unique opportunity to help shape the future of mobility from the ground up.

You will be responsible for planning, executing, and analyzing validation activities for differential and gearbox systems in e-drive applications. Working closely with design, simulation, and manufacturing teams, you will ensure that our components meet functional, durability, and NVH (noise, vibration, harshness) requirements. Your work will play a critical role in supporting industrialization and ensuring customer success.

Your responsibilities will be to:

• Define and execute test plans for design validation (DV) and production validation (PV)

• Develop test concepts and fixture designs for gear, shaft, and housing assemblies

• Coordinate prototype builds and validation samples with internal and external partners

• Program, monitor, and analyze endurance, strength, and NVH tests on test benches

• Analyze test data and create structured reports with clear conclusions and recommendations

• Support root cause analysis and issue resolution (in collaboration with design and quality)

• Contribute to the creation of validation documentation (DVP&R, test specs, test reports)

• Interface with suppliers, customers, and international teams on testing and release topics

Our requirements:

• Bachelor’s or Master’s degree in Mechanical Engineering, Automotive Engineering or related field

• Ideally more than 2 years of experience in years of experience in testing or validation of mechanical components or systems

• Prior exposure to automotive environments preferred

• Familiarity with drivetrain test benches, endurance and fatigue testing methods

• Hands-on experience with test setup, instrumentation, and data acquisition systems

• Experience in failure analysis, material characterization, NVH testing, gear performance evaluation, and durability testing is highly desirable

• Fluency in English is mandatory. German language proficiency is desirable, while fluency in Chinese would be a significant asset

• Analytical mindset with strong documentation and reporting skills

• Structured and proactive working approach, comfortable in dynamic environments

What we offer:

Be part of a dynamic team shaping the future of e-drive technologies through thorough testing and validation of gear and differential systems. You’ll work on strategically important projects from concept to industrialization, gaining hands-on experience in endurance, NVH, and durability testing. Collaborate with global teams and expand your expertise in failure analysis, material characterization, and advanced validation methods—all within a supportive and innovation-driven environment.
