This posting is for engineers with a background in wide-bandgap (WBG) power semiconductors, including GaN, SiC, or related technologies, at any career stage.\nWhere you spend most of your time will depend on your background and where the team needs help most. This could mean device modeling and simulation, on-wafer characterization, process integration, or failure analysis and reliability work.\nIf you have hands-on experience with wide-bandgap power devices and want to build a new device technology from the ground up, we want to hear from you.\nPotential Responsibilities\nSupport device architecture, process integration, and technology development for our vertical GaN power devices\n\nRun device modeling and simulation to inform design and process decisions\n\nPerform on-wafer and discrete device characterization, including DC, CV, and dynamic testing\n\nSupport failure analysis and reliability investigations for wide-bandgap power devices\n\nDevelop and review GDS layouts and test structures to support device learning and validation\n\nCollaborate with epitaxy, process, packaging, and reliability teams on cross-functional device work\n\nBuild and run application evaluation boards to connect device behavior to system-level performance\n\nKeep clear records of experiments, test data, and process learnings\n\nRequired Qualifications\nB.S., M.S., or PhD in Electrical Engineering, Physics, Materials Science, or a related field\n\nExperience with GaN, SiC, or other wide-bandgap semiconductors, ideally in power device applications\n\nHands-on experience in at least one of: device characterization, process integration, or device modeling and simulation\n\nComfortable working with data analysis tools such as Python or MATLAB\n\nStrong communication skills and the ability to work across disciplines\n\nLocation, Schedule & Working Conditions\nVertical Semiconductor's team is based on-site at our office at Greentown Labs in Somerville, MA.\nValues & Culture Fit\nVertical Semiconductor is seeking an engineer who is not only capable of accelerating the technical vision of the company but is also willing to get involved in the day-to-day execution of a startup. The ideal candidate is someone who enjoys tackling complex engineering challenges, is comfortable with a hands-on approach in a collaborative arena, and thrives in a startup environment where they can make an immediate impact. We value integrity, initiative, problem-solving, creativity, and a passion for creating transformative technology that can change industries and improve the world.\nTitle and Compensation\nWe offer a competitive salary and comprehensive benefits package with participation in our stock option program that is commensurate with candidates' experience and impact. Titles will also reflect candidates' experience.","description_format":"text","description_chars":3232,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Power Supplies & Power Electronics","Analog & Power Semiconductors"],"lifecycle":[{"event":"open","at":"2026-09-11T15:26:39Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.357,"p_room":0.28,"age_days":86,"expected_fill_days":33,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-15T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/verticalsemi-device-engineer","json_url":"https://alion.io/job/verticalsemi-device-engineer.json","meta":{"generated_at":"2026-10-15T12:11:48Z","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":18723,"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":686229},"rest":"https://alion.io/mcp/rest/get_company?id=686229"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fverticalsemi-device-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%2Fverticalsemi-device-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%2Fverticalsemi-device-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/verticalsemi-device-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fverticalsemi-device-engineer"}]}
