Job summary

Heron Power is a startup focusing on cutting-edge power electronics to enable grid-scale electrification. The Power Electronics Test & Validation Engineer will own application-specific testing of the SST across data centers, BESS, and PV projects, bringing up hardware, writing test scripts, and debugging performance against application requirements.

You will collaborate with Systems Integration, SW/FW teams, and pilot deployments to turn findings into product improvements.

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 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: 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 Her'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.
