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 focus 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\nThe Hardware Applications Engineer will own application-specific testing of Heron's solid state transformer (SST) across its core use cases: powering AI data centers, utility-scale BESS, and PV plants. That means bringing up hardware in the lab and at pilot sites, writing scripts to drive test equipment and power converters, and debugging performance against what each application demands, from MPPT performance and PPC/EMS/BMS communication to AI load smoothing and DC protection coordination. You will work hand in hand with the Systems Integration team: they own the SST platform; you own the applications.\nHow You Will Contribute\nOwn end-to-end application testing of a novel high C-rate battery pack (SuperBBU) with Heron's SST, validating ripple mitigation, backup capability, slew rates, and power-loss profiles.\n\nSupport SST and utility-scale BESS integration testing at pilot sites, covering EMS-to-SST communication, black start and grid-forming coordination, charge/discharge cycling, and round-trip efficiency.\n\nSupport integration testing of the SST with commercial off-the-shelf DAS, SCADA and EMS systems. \n\nOwn Heron's first pilot deployments: review field performance, identify feature gaps, and work with SW/FW teams to turn findings into product improvements.\n\nWrite and maintain Python-based test automation to command power converters, sequence tests, log data, and turn manual procedures into repeatable automated loops.\n\nSafely operate power converters, chillers, contactors, and protection hardware, and set up cabling, instrumentation, and data acquisition for high-power test runs.\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\n1+ years of hands-on experience in power electronics, energy storage, EV, grid, or a comparable hardware-intensive environment.\n\nStrong grasp on DC circuit fundamentals: resonances, parasitics, slew rates, and inductive spikes. You can correlate test data with simulation results.\n\nStrong scripting and test-automation skills to drive instruments and power converters and to log and analyze data.\n\nWorking knowledge of power conversion and battery systems: inverters and converters, BMS, DC pre-charge, contactors and protection, and thermal and cooling loops.\n\nComfort with lab instrumentation (oscilloscopes, power analyzers, DAQ systems) and comms protocols such as CAN and Modbus TCP.\n\nScrappy mindset: you get things done with a hundred hurdles in front of you.\n\nNice-to-Haves\nExperience with solid state transformers or grid-forming inverters.\n\nFamiliarity with utility-scale BESS commissioning, grid-support functions, or EMS integration.\n\nPrior experience in systems-level testing of power electronics or energy storage products\n\nHands-on experience with circuit and system simulation tools such as LTspice, Simscape, or PLECS.\n\nIf you are passionate about the energy transition and enjoy working at the frontier of power electronics and grid integration, 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 base salary range for this role is from $120,000 to $160,000K.","description_format":"text","description_chars":4370,"description_truncated":false,"requirements":{"experience_years_min":1,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Power Grid","Power Supplies & Power Electronics"],"lifecycle":[{"event":"open","at":"2026-10-16T20:35:14Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":0,"expected_fill_days":61,"reasons":["conf:0","velocity","win:early","comp:junior"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":120000,"is_top_pay":false},"html_url":"https://alion.io/job/heron-power-hardware-applications-engineer","json_url":"https://alion.io/job/heron-power-hardware-applications-engineer.json","meta":{"generated_at":"2026-10-18T07:06:46Z","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":10574,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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%2Fheron-power-hardware-applications-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%2Fheron-power-hardware-applications-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%2Fheron-power-hardware-applications-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/heron-power-hardware-applications-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fheron-power-hardware-applications-engineer"}]}
