SST & BESS Systems Integration Engineer (Equity)

Heron Power; Scotts Valley (CA); On-site; USD 130,000 - 160,000; Full time

Job summary

Heron Power is a startup building cutting-edge power electronics for the grid. The Systems Integration Engineer will own application testing of the SST across AI data centers, utility-scale BESS, and PV plants, bring up hardware, write scripts, and debug performance against what each application demands.

You will collaborate with the Systems Integration team to ensure SST platform success, own pilot deployments, and develop repeatable automated test loops in Python while safely operating

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; correlate test data with simulations.
• 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, protection, and cooling.
• Comfort with lab instrumentation (oscilloscopes, power analyzers, DAQ) and comms protocols such as CAN and Modbus TCP.
• Scrappy mindset: you get things done with a hundred hurdles in front of you.

Responsibilities

• Own end-to-end application testing of a novel high C-rate battery pack (SuperBBU) with Heron's SST, validating ripple mitigation, backup capability, slew rates, and power-loss profiles.
• Support SST and utility-scale BESS integration testing at pilot sites, covering EMS-to-SST communication, black start and grid-forming coordination, charge/discharge cycling, and round-trip efficiency.
• Support integration testing of the SST with commercial off-the-shelf DAS, SCADA and EMS systems.
• Own Heron's first pilot deployments: review field performance, identify feature gaps, and work with SW/FW teams to turn findings into product improvements.
• Write and maintain Python-based test automation to command power converters, sequence tests, log data, and turn manual procedures into repeatable automated loops.
• Safely operate power converters, chillers, contactors, and protection hardware, and set up cabling, instrumentation, and data acquisition for high-power test runs.
