About the role
TL;DR
Own application-specific testing of Heron's solid state transformer (SST) across its core use cases.
- •You will own application-specific testing of Heron's solid state transformer (SST) across its core use cases: powering AI data centers, utility-scale BESS, and PV plants.
- •Key Responsibilities Own end-to-end application testing of a novel high C-rate battery pack (SuperBBU) 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: 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.
- •Requirements 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.
- •You can 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.
