We aim to debottleneck the growth of electricity generation and consumption with scalable, innovative, and less costly hardware solutions, accelerating the electrification of everything.\nOur first goal is to build better converters (inverters & rectifiers) to connect large-scale renewables, storage, and loads to the grid. Heron Power’s leadership team is made up of seasoned veterans who have designed and shipped gigawatts of power conversion products over the past decade.\nWe 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.\nJob Overview\nAs a Senior Power Electronics Engineer, you will lead the design and development of high-power, grid-connected converter hardware. You will be part of a small, focused engineering team responsible for delivering robust and efficient power conversion systems from concept through production. Your work will span early-stage architecture, detailed circuit and system design, simulation, prototyping, validation, and product industrialization. You will collaborate cross-functionally with teams across firmware, mechanical, reliability, and manufacturing to ensure seamless integration and high performance. This role is ideal for someone who thrives in a fast-paced environment, values ownership, and is passionate about advancing energy technology.\nHow You Will Contribute\nArchitect, design, and deliver grid-tied power converters.\n\nOwn the full hardware development lifecycle-from requirements definition and modeling through schematic capture, PCB layout, prototyping, testing, validation, and manufacturing support.\n\nDevelop detailed electrical models of converter circuits and topologies to support performance analysis and design optimization.\n\nSelect power components, design protection circuitry, and ensure compliance with relevant safety and grid standards.\n\nCollaborate closely with systems, mechanical, layout, firmware, reliability, and manufacturing teams to bring designs from concept to production at scale.\n\nDrive innovation in power converter architectures to achieve industry-leading performance in efficiency, power density, and reliability.\n\nWhat You Will Bring\nWe 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.\nMust-Have Requirements\nDegree in Electrical Engineering or equivalent practical experience.\n\nMinimum 3 years of hands-on experience in the design, prototyping, testing, and industrialization of power converters.\n\nDeep understanding of power electronics topologies, both theoretical and applied, including isolated and non-isolated architectures.\n\nProven experience with high-voltage semiconductor devices such as IGBTs, Si/SiC MOSFETs, and diodes, as well as design of gate drivers and sensing circuits.\n\nStrong grasp of magnetic component design and selection-inductors, transformers-as well as capacitor types (film, ceramic, electrolytic) for high-voltage/high-frequency operation.\n\nSolid understanding of switching behavior, semiconductor loss mechanisms, and experience with power loss and thermal modeling.\n\nProficient in schematic capture, simulation tools (SPICE, PLECS, LTspice, Simulink etc.), and familiar with lab instrumentation such as oscilloscopes, network analyzers, and power analyzers.\n\nExperience in PCB layout for power electronics, including strategies to reduce parasitics, improve thermal management, and ensure manufacturability and EMC compliance.\n\nWorking knowledge of product safety, reliability, and environmental standards for industrial applications.\n\nBasic understanding of control systems and experience working with embedded firmware; familiarity with UL, CE, and grid interconnection standards (such as IEEE 1547, UL347A, etc.) relevant to power converters.\n\nWork authorization in the United States\n\nNice-to-Haves\nExperience designing or testing medium-voltage systems (e.g., 5kV-35kV), including insulation coordination, clearance/creepage, and partial discharge considerations.\n\nFamiliarity with grid-tied hardware such as medium-voltage converters, switchgear, circuit breakers, or protective relays.\n\nKnowledge of insulation materials, shielding techniques, and arc flash mitigation for high-voltage systems.\n\nBackground in reliability engineering and accelerated life testing (HALT, HASS, FMEA) for power electronics.\n\nExposure to manufacturing processes for high-power assemblies (e.g., busbars, potting, conformal coating, HV connectors).\n\nHands-on experience with test automation using Python, LabVIEW, or embedded scripting for power hardware validation.\n\nParticipation in standards committees or familiarity with emerging grid codes and interconnect standards is a plus.\n\nIf you are passionate about technology and enjoy working in a fast-paced environment, we would love to hear from you. Join us in accelerating the electrification of everything at Heron Power.\nHeron Power provides competitive compensation (salary and equity) and benefits. The salary for this role ranges from $120,000 to $200,000 per year.","description_format":"text","description_chars":5531,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Electrical & Electronic Engineering","Energy & Utilities"],"lifecycle":[{"event":"open","at":"2026-06-12T18:21:58Z"}],"visa":[],"liveness":{"score":22,"band":"cold","label":"Long shot","p_open":1,"p_active":0.802,"p_room":0.28,"age_days":124,"expected_fill_days":61,"reasons":["conf:0","velocity","win:tail","crowd:"],"computed_at":"2026-10-15T05:46:00Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":false},"html_url":"https://alion.io/job/heronpower-seniorstaff-power-electronics-engineer","json_url":"https://alion.io/job/heronpower-seniorstaff-power-electronics-engineer.json","meta":{"generated_at":"2026-10-15T13:21:10Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":20672,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":5370},"rest":"https://alion.io/mcp/rest/get_company?id=5370"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fheronpower-seniorstaff-power-electronics-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fheronpower-seniorstaff-power-electronics-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fheronpower-seniorstaff-power-electronics-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/heronpower-seniorstaff-power-electronics-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fheronpower-seniorstaff-power-electronics-engineer"}]}
