Intern, System Integration & Test Software

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 You will build and operate the test infrastructure we use to validate grid-tied converters across the full product lifecycle — from system architecture and integration through reliability validation and manufacturing test at scale. This role owns a meaningful slice of the development loop: test system design, test execution, data analysis, failure isolation, verified fixes, and the software platforms that automate and orchestrate it all. You will uncover real design and process failures by running physical tests and building automated equipment, data workflows, and AI-driven execution systems. We prioritize a strong foundation in first principles, practical skill, and a bias toward getting things done. We care as much about how you work as what you already know. HOW YOU WILL CONTRIBUTE Test Software, Automation, and AI Agents - Contribute to our software test infrastructure for system integration and reliability testing — test architecture, hardware abstraction layers, and result reporting pipelines. - Write software tests that interact directly with hardware and firmware over CAN, UART, Modbus, TCP/IP — debugging signal integrity, protocol failures, and firmware edge cases. - Write concurrent, fault-tolerant software for our next-generation manufacturing test platform: Firmware Flashing, FCT, EOL stations running autonomously on the factory floor. - Build AI agents that manage test execution across facilities — initiating runs, monitoring anomalies, implementing test script and firmware changes in response to failures, and routing issues to humans - Build the operator and engineering facing management platforms: live tester status, pass/fail rates, station health, and agent activity across all facilities. System Integration, Reliability & Test Execution - Own system-level integration testing for new firmware and hardware revisions — bring-up, functional validation, and regression coverage across power electronics, firmware, and connected systems. - Execute reliability campaigns—burn-in, power cycling, thermal stress, and abuse tests—and evolve them as we learn where the real failure cliffs are. - Drive fast debug loops during excursions: isolate, instrument deeper, reproduce, and verify that corrective actions eliminate the failure. Test Bench Architecture & Build - Design and build electrical reliability test benches for power electronics hardware—inverters, DC/DC converters, bi-directional power stages. - Specify, procure, and integrate lab equipment: programmable power supplies, electronic loads, DAQ systems, sensors, protection hardware, interlocks, and cabling. WHAT YOU WILL BRING We prioritize a strong foundation in first principles, practical skill, an inquisitive mindset, and a proactive attitude. We care as much—or more—about how you work as what you already know. Must-Have - Pursuing a BS or MS in Electrical Engineering, Mechatronics, Computer Engineering, or a related field. - Strong programming proficiency in Python or Go; abilit
