Sr. Test Engineer, Energy Reliability

What To Expect At Tesla Energy

Delivering reliable energy products at scale requires rigorous validation and deep hands-on expertise in medium-voltage systems. As a Senior Reliability Test Engineer focused on Medium Voltage, your responsibilities include:

• Leading and executing medium-voltage installation, commissioning, and acceptance testing for power electronics systems, assemblies, and integrated cabinets.
• Designing, building, and maintaining scalable automated test frameworks (Python/Pytest, LabVIEW/TestStand) for MV power electronics, with emphasis on dielectric, insulation, connection, and termination of integrity tests.
• Developing and automating medium-voltage test sequences including insulation resistance, hi-pot, partial discharge (PD) detection, power factor/tan-delta, and bushing integrity tests at the device, assembly, and cabinet level; selecting and integrating appropriate HV/MV instrumentation (PD couplers, capacitive dividers, differential HV probes, PD analyzers).
• Designing reusable, modular test libraries for hardware bench testing and production line screening — enabling teams to spin up new test coverage quickly.
• Integrating 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 automating HALT, ALT, and burn-in sequences — sequencing climate/vibration chambers, power supplies, and measurement instruments as a single orchestrated system.
• Building automated data acquisition pipelines feeding directly into reliability dashboards to expedite lifetime reliability estimates, degradation trends, and pass/fail analytics refreshed in real time.
• Applying ML-assisted anomaly detection to identify unit outliers during production screening and predict failure signatures before they reach the field.
• Continuously driving design risk burndown to ensure product reliability and durability; performing reliability testing for industrial and residential energy power converters.
• Determining component and system-level test solutions that optimize product reliability and durability through DFMEA-based risk mitigations, resource planning, and program scheduling; facilitating failure analysis to understand root causes and drive resolution for failures originating in testing.

Qualifications

• Degree in Electrical Engineering, or a related engineering discipline
• 3-10 years of hands-on experience in power electronics hardware design, design validation, hardware testing, mechanical system reliability, and durability testing
• Experience working safely with high voltage systems; familiarity in relevance to IEEE/IEC safety standards
• Hands-on experience with high-voltage test disciplines — partial discharge measurement, insulation/dielectric testing, transformer design validation, and bushing characterization; experience selecting and operating HV instrumentation (PD detectors, HV dividers, AC/DC hipot sets, LCR meters at HV)
• Knowledge of programming in scripting languages for test automation and data analysis/post-processing. Experience with test automation and data analysis using scripting languages (Python strongly preferred; Pytest, Robot Framework, LabVIEW/TestStand highly valued)
• Experience specifying sensors for test instrumentation and utilizing data acquisition systems
• Experience proactively 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)
