The Impact You’ll Make

We are looking for a hands-on Senior Test Engineer with 5+ years of experience developing and executing automated tests for power electronics and renewable energy systems. In this role, you will build test capability for solar photovoltaic (PV), battery energy storage systems (BESS), power conversion systems (PCS), inverters, DC/DC converters, and related grid-connected power equipment. You will use LabVIEW and Python to automate complex electrical tests, integrate laboratory instruments, validate product performance, support safety and compliance certification, and drive design verification and reliability testing from prototype through product release.

The ideal candidate combines strong power electronics fundamentals with practical laboratory experience, test automation skills, and a methodical approach to troubleshooting, test documentation, and root-cause investigation.

Key Responsibilities

Test Development & Automation

• Develop, maintain, and debug automated test systems using LabVIEW and Python for power electronics, solar, and energy storage products.
• Create reusable test frameworks, instrument drivers, sequence control, data logging, reporting, and automated pass/fail evaluation.
• Interface with laboratory equipment through SCPI, VISA, Ethernet, USB, serial, CAN, and other applicable communication protocols.
• Develop repeatable, traceable test scripts and procedures suitable for engineering validation and production use.
• Manage test software revisions, calibration records, test configurations, and measurement-system documentation.

Power Electronics & Renewable Energy Testing

• Develop and execute tests for PV inverters, power conversion systems (PCS), bidirectional converters, DC/DC converters, battery interfaces, and grid-connected power systems.
• Characterize efficiency, power quality, dynamic response, transient behavior, thermal performance, protection functions, and operating limits.
• Test across operating voltage, current, power, temperature, load, and grid conditions.
• Troubleshoot electrical, control, firmware, instrumentation, and system-integration issues in high-voltage laboratory environments.

Laboratory Equipment & Instrumentation

• Configure and operate PV simulators and solar-array simulators, including programmable I-V curves and dynamic irradiance profiles.
• Operate regenerative grid simulators and grid emulators for AC source, grid disturbance, and grid-interconnection testing.
• Use battery simulators, battery cyclers/testers, bidirectional DC sources, and programmable electronic loads.
• Use oscilloscopes, differential and current probes, power analyzers, digital multimeters, data-acquisition systems, and precision current/voltage sensors.
• Work with thermal chambers, thermocouples, infrared cameras, insulation/hipot testers, ground-bond testers, and other environmental or safety equipment
