Systems Integration Engineer, SST & BESS Applications

The role

The Systems Integration Engineer will own application-specific testing of Heron's solid state transformer for AI data centers, utility-scale BESS, and PV plants. This involves bringing up hardware in labs and pilot sites, writing Python test automation, and debugging performance.

What you will do

• Own end-to-end application testing of a high C-rate battery pack with Heron's SST.
• Support SST and utility-scale BESS integration testing at pilot sites.
• Support integration testing of the SST with commercial off-the-shelf DAS, SCADA and EMS systems.
• Own Heron's first pilot deployments by reviewing field performance and identifying feature gaps.
• Write and maintain Python-based test automation to command power converters and log data.
• Safely operate power converters, chillers, contactors, and protection hardware.
• Set up cabling, instrumentation, and data acquisition for high-power test runs.

Required qualifications

• 5+ years of hands-on experience in power electronics, energy storage, EV, grid, or a comparable hardware-intensive environment.
• Strong grasp on DC circuit fundamentals: resonances, parasitics, slew rates, and inductive spikes.
• Ability to correlate test data with simulation results.
• Strong scripting and test-automation skills to drive instruments and power converters and to log and analyze data.
• Working knowledge of power conversion and battery systems: inverters and converters, BMS, DC pre-charge, contactors and protection, and thermal and cooling loops.
• Comfort with lab instrumentation (oscilloscopes, power analyzers, DAQ systems) and comms protocols such as CAN and Modbus TCP.
• Scrappy mindset.

Nice to have

• Experience with solid state transformers or grid-forming inverters.
• Familiarity with utility-scale BESS commissioning, grid-support functions, or EMS integration.
• Prior experience in systems-level testing of power electronics or energy storage products.
• Hands-on experience with circuit and system simulation tools such as LTspice, Simscape, or PLECS.
