Heron Power is a startup company building cutting-edge power electronics for the 21st-century grid. We aim to debottleneck the growth of electricity generation and consumption with scalable, innovative, and less costly hardware solutions, accelerating the electrification of everything.
Our first goal is to build better converters (inverters & rectifiers) to connect large-scale renewables, storage, and loads to the grid. Heron's leadership team is made up of seasoned veterans who have designed and shipped gigawatts of power conversion products over the past decade.
Job Overview
This role provides hands-on experience working with real power converter hardware and magnetics, supporting engineering efforts from early prototype evaluation through system-level validation.
How You Will Contribute
Support the validation and characterization of medium-voltage magnetic components including inductors, transformers, planar magnetics, magnetic current sensors, and common-mode chokes
Assist in developing and executing test plans to evaluate magnetic performance, including inductance, loss, saturation, thermal behavior, and insulation integrity
Perform laboratory measurements using oscilloscopes, impedance analyzers, LCR meters, power analyzers, and thermal measurement tools
Analyze switching waveforms to evaluate magnetic performance within power converter systems
Support EMI/EMC validation efforts, including evaluation of common-mode chokes and filtering components
Assist with electromagnetic modeling and FEA simulations to analyze magnetic fields, losses, and parasitic effects
Help evaluate PCB layout and physical implementation to identify parasitic inductance, capacitive coupling, and EMI-related issues
Assist in building, assembling, and modifying prototype magnetic components and test fixtures
Collect, analyze, and document experimental data and compare results with design expectations and simulation models
Collaborate with power electronics, mechanical, and layout engineers to support magnetics integration and performance optimization
