Electrical Engineer - Manufacturing Test

WHAT TO EXPECT Heron Power is a startup company building cutting-edge power electronics for the 21st-century grid. We aim to de-bottleneck 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. 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 environment, driven by first principles engineering, solving difficult problems—with a strong bias toward hands-on execution and learning by doing. JOB OVERVIEW High-reliability products are built on high-quality manufacturing and test infrastructure. As an Electrical Engineer – Manufacturing Test, you will help develop the hardware, fixtures, and test solutions that ensure our products can be built, validated, and shipped at scale. Working closely with design engineers, manufacturing partners, and external fixture vendors, you will support the development and deployment of production test systems for PCBAs, subsystems, and integrated products. This role sits at the intersection of electrical engineering, manufacturing, and product development. You will gain hands-on experience developing test fixtures, supporting Design for Manufacturability (DFM) and Design for Test (DFT) initiatives, troubleshooting hardware issues, and helping bring new products from prototype through production. If you enjoy understanding how products are built, tested, and scaled into manufacturing, this role will feel like home. HOW YOU WILL CONTRIBUTE TEST STRATEGY & DEVELOPMENT - Support the development of functional test coverage for PCBAs, subsystems, and production systems. - Review schematics, PCB layouts, and manufacturing documentation to define test requirements and validation plans. - Partner with design engineers to improve Design-for-Test (DFT) and Design-for-Manufacturability (DFM), including test points, diagnostics, firmware validation, and observability. - Help establish pass/fail criteria grounded in product performance, reliability, and manufacturing requirements. - Participate in engineering validation, production qualification, and end-of-line (EOL) test activities. TEST HARDWARE & FIXTURE DEVELOPMENT - Design, modify, and support electrical test fixtures for PCBA validation and production testing. - Collaborate with external fixture vendors to develop and deploy manufacturing test solutions. - Support the development of bed-of-nails fixtures, interface boards, harness validation fixtures, and other production test hardware. - Specify, integrate, and troubleshoot instrumentation including oscilloscopes, DMMs, power supplies, electronic loads, DAQs, and communication interfaces. - Help deliver test stations that are reliable, maintainable, safe, and scalable. PRODUCTION SUPPORT & DEBUG - Support board bring-up, hardware validation, and root-cause analysis of electrical issues. - Drive rapid debug loops when tests fail. - Improve test observability and diagnostic resolution. - Partner with manufacturing, quality, and engineering teams to improve yield, reduce escapes, and accelerate learning cycles. - Support pilot builds, NPI activities, and production ramps. CONTINUOUS IMPROVEMENT - Generate manufacturing documentation, test procedures, and engineering change requests. - Support fixture maintenance, calibration, and continuous improvement efforts. - Help close the loop between manufacturing, design, and reliability teams. - Contribute to improving test coverage, manufacturing efficiency, and product quality
