## About the Role

* 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)

## Description

* 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
