Power Electronics PCBA Technician

What to Expect 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. We understand that no one individual knows everything.  We will all learn  a lot  together and from each other.  We strive to build a collaborative, enriching environment conducive to personal, technical, and career growth.  You can expect to work in a dynamic and collaborative environment, driven by first principles engineering, solving difficult problems.

Job Overview We are looking for a skilled Engineering Technician to support rapid prototyping, engineering builds, lab test setups and reworks across electrical, mechanical and electromechanical assemblies. This role is hands-on and essential to ensuring the reliability and quality of our product. You will lead the deployment of R&D lab processes and drive hands-on fabrication, assembly, test and troubleshooting of new products and product variants through all phases of the engineering lifecycle. Your technical and timely feedback to the engineering team is pivotal to drive product improvements and advancements with specific attention to safety, quality and reliability. This role is versatile in nature and welcomes innovative, outside-of-the-box thinking to drive excellence in our products.

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

What You Will Bring 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

Experience in teardown, diagnostic and troubleshooting of complex manufactured assemblies

Familiarity and experience using hand and power tools (drills, saws, grinders), soldering/rework stations, and common lab equipment

Ability to read and interpret engineering drawings, schematics, wiring diagrams and work instructions to translate designs into physical builds

Ability to work independently and as part of a team

Strong problem-solving skills and attention to detail

Excellent communication and interpersonal skills

Ability to navigate ambiguity and take complete ownership of change management through various product iterations and experiments

Ability to lift up to 50 lbs., with frequent standing, walking and bending

Nice to Haves Demonstrated strong electrical aptitude and experience with electronic assemblies and PCBAs

Experience with power electronics measurement equipment — oscilloscopes, multimeters, power analyzers, hipot testers

Experience building wire harnesses, cable assemblies, or wiring test setups for motor controls and instrumentation

3D Printing, CNC, Laser Cutting, Milling/Drilling, CATIA, SolidWorks experience a plus

Experience in PCB rework, sheet metal fabrication, or mechanical prototyping

IPC soldering certification (e.g., IPC-A-610, J-STD) a plus

Prior experience in an R&D, NPI or similar rapid-iteration environment preferred
