Founded in 2006, our innovative microinverter technology revolutionized solar power, making it a safer, more reliable, and scalable energy source. Today, the Enphase Energy System enables users to make, use, save, and sell their own power. Enphase is also one of the most successful and innovative clean energy companies in the world, with more than 80 million products shipped across 160 countries.\nJoin our dynamic team designing and developing next-gen energy technologies and help drive a sustainable future!\nAbout The Role\nThis position sits within the core Engineering R&D group focused on our Solid-State Transformer (SST) platform. Our team is responsible for defining and delivering the next-generation power module, with higher power density to reduce footprint and thermal load. We're looking for a technically deep power electronics engineer focused on increasing efficiency while reducing cost per watt.\nWhat You Will Do\nDesign and develop power conversion circuits and magnetics for the SST platform, optimizing for power density, efficiency, and thermal performance\nEvaluate and integrate advanced power semiconductor devices (particularly, GaN) and planar magnetics to increase power throughput while shrinking module footprint\nTranslate modeling and simulation results into benchtop prototypes, and reconcile differences between predicted and measured performance\nDrive design trade-offs across power density, efficiency, thermal management, and cost per watt to meet next-generation product targets\nCo-design with mechanical and thermal engineering to jointly optimize packaging, cooling, and power density, and collaborate with controls engineering to integrate power modules into the SST platform\nLead root-cause analysis and design iteration based on test data to continuously improve power density and reliability\nWho You Are and What You Bring\nB.S., M.S., or Ph.D. in Electrical Engineering or closely related field\nEngineer: BS + 3 yrs | MS +1 yr; Senior Engineer: BS + 5 yrs | MS + 3 yrs | PhD + 1yr\nTypically, 6+ years of electronics hardware/system design experience (or equivalent depth of experience)\nHands-on experience in the full cycle of schematic capture, layout, and testing of power electronics, particularly if focused on power density\nProficiency with one or more ECAD tools such as OrCAD, KiCad, or Altium\nAbility to translate modeling and simulation to benchtop performance and be able to reconcile differences between theory and practice\nFamiliarity with advanced power semiconductor devices and magnetics (particularly planar transformers)\nExperience co-designing power electronics with mechanical and thermal engineering teams, balancing electrical performance against packaging and cooling constraints. Familiarity with a mechanical CAD tool such as SolidWorks, Fusion 360, or FreeCAD is a plus.\nAbility to lead technical execution of significant power electronics designs with a high degree of autonomy, including digital controls and automation for testing, escalating major trade-offs as needed\nExperience mentoring less experienced engineers and contributing to technical design reviews within the team\nThe base salary range for this position in Petaluma, CA is $105,000 to $162,000 and may vary based on experience, skills, and location.\nThis position is also eligible for bonus, equity, and benefits, with final compensation determined in accordance with applicable laws and internal equity.","description_format":"text","description_chars":3588,"description_truncated":false,"requirements":{"experience_years_min":6,"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","Solar Energy"],"lifecycle":[{"event":"open","at":"2026-10-21T08:14:47Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 24 · green card filings: 1","filings_12m":24,"filings_prev_12m":14,"green_card_filings_12m":1,"median_offered_wage_usd":141500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":9}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":27,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-10-23T05:54:15Z"},"pay":{"stated_usd_annual":162000,"is_top_pay":false},"html_url":"https://alion.io/job/enphase-energy-senior-power-electronics-engineer","json_url":"https://alion.io/job/enphase-energy-senior-power-electronics-engineer.json","meta":{"generated_at":"2026-10-23T09:18:42Z","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":14888,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":58551},"rest":"https://alion.io/mcp/rest/get_company?id=58551"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fenphase-energy-senior-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%2Fenphase-energy-senior-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%2Fenphase-energy-senior-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/enphase-energy-senior-power-electronics-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fenphase-energy-senior-power-electronics-engineer"}]}
