Senior Reliability Test Engineer, Energy Products (m/f/d)

What to Expect

At Tesla Engineering Germany in Freiburg, we’re building the future of sustainable energy by developing innovative power electronics for energy storage and vehicle charging systems. Join our team to collaborate across different engineering areas, solve meaningful challenges creatively and transfer concepts from initial design, through prototyping and testing into real-world solutions.This is an opportunity to support key projects, use modern tools, and work in state-of-the-art facilities to create technologies that shape how energy systems evolve. You get to work on advancing power electronics used for Tesla products globally, thereby directly contributing to the acceleration of the world's transition to sustainable energy.

What You’ll Do

• Design, build, and maintain scalable automated test frameworks (Python/Pytest, Robot Framework, LabVIEW/TestStand) for high-voltage power electronics systems. Own end-to-end Automated Test Equipment development — from instrument driver abstraction to test orchestration, data capture, and report generation. Design reusable, modular test libraries for hardware bench testing and production line screening — enabling teams to spin up new test coverage quickly
• Integrate test suites into CI/CD pipelines (Jenkins, GitHub Actions) so every firmware or hardware revision is automatically validated against a reliability baseline before it reaches review, and automate HALT, ALT, and burn-in sequences — sequencing climate/vibration chambers, power supplies, and measurement instruments as a single orchestrated system
• Build automated data acquisition pipelines feeding directly into reliability dashboards to expedite lifetime reliability estimates, degradation trends, and pass/fail analytics refreshed in real time and collaborate cross-functionally with design, reliability, and manufacturing engineers to suggest design and process improvements, addressing reliability and durability issues based on understanding of failure root causes
• Continuously drive design risk burndown to ensure product reliability and durability; perform reliability testing for industrial and residential energy power converters
• Determine component and system-level test solutions that optimize product reliability and durability through DFMEA-based risk mitigations, resource planning, and program scheduling; facilitate failure analysis to understand root causes and drive resolution for failures originating in testing

What You’ll Bring

• BS/MS degree in Electrical Engineering, or a related engineering discipline
• 3-10 years of hands-on experience in +2kV power electronics hardware design, design validation, hardware testing, mechanical system reliability, and durability testing
• Knowledge of programming in scripting languages for test automation and data analysis/post-processing and experience specifying sensors for test instrumentation and utilizing data acquisition systems
• Experience pro-actively owning and delivering test engineering projects within accelerated validation timelines
• Proven ability to develop reliability and durability test setups, including environmental, mechanical, and electrical stress testing, highly preferred
• Preferred to have experience of common automotive communication protocols (CAN, Ethernet)
