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’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 Mechanical Engineer, you will design, develop, and validate cutting-edge medium-voltage power electronics systems. You will design a wide range of associated parts and assemblies using a first principles design approach. Your role will involve performing a variety of tasks, including CAD, analysis, prototyping, testing, and hands-on work. You will collaborate closely with electrical, test, and manufacturing engineering teams, as well as external suppliers. You will own your designs from concept through high-volume production.\nHow You Will Contribute\nDesign mass-manufacturable parts and assemblies for power converters, such as enclosures, plastics, heatsinks, insulators, transformers, connectors, PCBAs, bolted joints, and adhesive joints\n\nOwn parts and assemblies from initial concept to high volume production\n\nDesign with a first principles approach, optimizing parts through analysis (e.g. structural, thermal, tolerance)\n\nCreate 3D designs and 2D drawings using CATIA V6/3DX\n\nPerform hands-on work such as prototyping and testing\n\nCollaborate with different engineering disciplines, including mechanical, electrical, manufacturing, and reliability teams, as well as external partners and suppliers\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\nBachelor's degree in mechanical engineering, mechatronics, or similar\n\n4+ years of full-time industry experience\n\nDemonstrated exceptional ability designing mechanical parts or assemblies\n\nDemonstrated exceptional ability working with 3D CAD (bonus if there is experience with CATIA V6/3DX)\n\nStrong engineering fundamentals including a basic understanding of electronics\n\nExperience designing electromechanical parts or assemblies\n\nExperience with high volume manufacturing and processes such as fastening, sheet metal bending, stamping, injection molding, diecasting, extruding, and dispensing\n\nExcellent communication and interpersonal skills\n\nAbility to work independently and as part of a team\n\nStrong problem-solving skills and attention to detail\n\nNice-to-Haves\nExperience designing power electronics converters\n\nExperience with PCBAs, connectors, fuses, and other electronic components\n\nExperience with FEA, CFD, multi-physics modeling, or associated software (Ansys, MATLAB, Python, Simulink, StarCCM, etc.)\n\nExperience with GD&T and tolerance analysis\n\nExperience with reliability and validation testing, as well as DFMEAs\n\nExperience with product lifecycle management (PLM) and controlled release processes\n\nExperience with medium voltage (34.5kV) or grid-related products, such as converters, switchgear, circuit breakers, insulation, and shielding\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 Heron Power.\nHeron Power provides competitive compensation (salary and equity) and benefits. The salary for this role ranges from $120,000 to $220,000 per year.","description_format":"text","description_chars":4145,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Electrical & Electronic Engineering","Power Grid","Power Supplies & Power Electronics"],"lifecycle":[{"event":"open","at":"2026-10-15T16:15:48Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":9,"expected_fill_days":61,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-10-25T05:49:26Z"},"pay":{"stated_usd_annual":220000,"is_top_pay":true},"html_url":"https://alion.io/job/heron-power-seniorstaff-mechanical-engineer-power-electronics","json_url":"https://alion.io/job/heron-power-seniorstaff-mechanical-engineer-power-electronics.json","meta":{"generated_at":"2026-10-25T21:39:37Z","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":30602,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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-seniorstaff-mechanical-engineer-power-electronics"},{"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-seniorstaff-mechanical-engineer-power-electronics"},{"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-seniorstaff-mechanical-engineer-power-electronics"},{"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-seniorstaff-mechanical-engineer-power-electronics\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fheron-power-seniorstaff-mechanical-engineer-power-electronics"}]}
