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 focus 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
How You Will Contribute
Build, assemble and modify prototype units and sub-assemblies from engineering drawings, schematics and verbal instructions - spanning PCBA, mechanical, and electromechanical work
Fabricate and prepare test fixtures, wire harnesses and cable assemblies using hand tools, crimp tools, and soldering equipment
Set up, configure and operate lab test equipment and instrumentation for engineering validation, environmental testing and performance characterization
Perform mechanical fabrication tasks including drilling, cutting, grinding, bending and light sheet metal modification to support prototype and fixture builds
Tear down, diagnose and troubleshoot complex manufactured assemblies to identify failure modes and root causes
Collaborate with cross-functional teams (including engineering, reliability, test and operations) to develop processes for prototype builds, test, failure mode identification and troubleshooting playbooks through various experimental setups and systems
Document learnings and failure modes, analyze data and communicate findings to cross-functional teams to drive product changes into future builds and execute incremental improvements
Maintain lab equipment, tooling, and test infrastructure in a state of good repair; support calibration and preventive maintenance schedules
Requirements
We have a short list of must-have requirements. We prioritize a strong grip on first principles, hands-on skills, and a sense of initiative. Domain-specific knowledge and experience will help determine the career level for each hire.
Must Have Requirements
Proven track record of hands-on technical assembly, fabrication, troubleshooting and diagnostic experience across electrical, mechanical or electromechanical systems
