Senior Applications Engineer

About the role

Heron Power develops power electronics designed to modernize the electrical grid through scalable hardware. You will join a team of industry veterans to validate solid state transformer technology for data centers, battery storage, and solar installations.

Key facts

What you'll do

• Manage end-to-end application testing for the SuperBBU battery pack and SST, focusing on ripple mitigation, backup performance, and power-loss profiles.
• Coordinate integration testing at pilot sites, including EMS-to-SST communication, black start procedures, and grid-forming functions.
• Validate SST integration with commercial SCADA, DAS, and EMS systems.
• Lead initial pilot deployments by analyzing field data and collaborating with software and firmware teams to refine product features.
• Develop Python-based automation scripts to control power converters, manage test sequences, and log data.
• Perform high-power lab operations, including setup of chillers, contactors, instrumentation, and cabling.

Requirements

• 5+ years of professional experience in energy storage, power electronics, grid systems, or EV hardware.
• Deep understanding of DC circuit fundamentals, including parasitics, resonances, inductive spikes, and slew rates.
• Ability to bridge the gap between simulation results and physical test data.
• Proficiency in scripting for test automation, instrument control, and data analysis.
• Experience with battery management systems, power converters, thermal loops, and DC protection hardware.
• Practical lab skills using DAQ systems, power analyzers, and oscilloscopes.
• Familiarity with communication protocols like Modbus TCP and CAN.

Nice to have

• Background in grid-forming inverters or solid state transformers.
• Experience with utility-scale BESS commissioning or EMS integration.
• History of systems-level testing for energy storage or power electronics.
• Simulation experience using PLECS, Simscape, or LTspice.
