Develops solutions for home, business, and sustainable energy resilience, including power electronics, energy storage, and connected energy products.

What you will do

• Lead system validation for assigned products and releases, including planning, execution, reporting, and completion.
• Translate requirements, use cases, and risks into validation plans, test cases, and measurable acceptance criteria.
• Develop Python-based automated tests, reusable libraries, regression coverage, and scalable test infrastructure.
• Design and troubleshoot test setups integrating products, laboratory instruments, programmable power equipment, and communication interfaces.
• Evaluate normal, limit, fault, and connected-device behavior; investigate failures using measurements, communication traces, logs, and test data.
• Maintain DVP&R traceability, communicate technical risks and release concerns, coordinate corrective actions, and mentor junior engineers.

Requirements

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related engineering discipline.
• At least 5 years of relevant engineering experience validating or testing power electronics, energy storage, or embedded electrical systems.
• Proficiency in Python for test automation, instrument or device control, and data analysis.
• Hands-on experience troubleshooting electrical hardware and interpreting schematics, measurements, and system behavior.
• Experience testing inverters, DC converters, controllers, or comparable electrical systems.
• Experience with oscilloscopes, power analyzers, programmable AC/DC sources, and electronic or passive loads.
• Experience integrating automated hardware test setups through CAN, Modbus, Ethernet, RS-232, RS-485, or MQTT.
• Ability to design experiments, define pass/fail criteria, analyze results, and distinguish product failures from test setup issues.
• Working knowledge of Linux, shell/Bash scripting, Git, and issue-tracking tools such as Jira.

Nice to have

• Master’s degree.
• Experience with lithium-ion battery systems, battery management systems, solar microinverters, or integrated energy storage products.
• Experience developing automated regression frameworks using pytest.
• Familiarity with C, C++, and Python for understanding or debugging embedded firmware behavior.
• Experience with remotely operated test systems, continuous integration, or distributed test infrastructure.
• Familiarity with power electronics, energy storage, or grid-interconnection standards.
