Rigorous testing is what turns a promising prototype into a product our customers can trust - and what gets us from validated prototype to Alpha customer readiness to volume shipments.\nAs Test Engineer, you will design and execute test plans for our power conversion systems - from functional and target-parameter verification through stability, endurance and load testing. You will build and maintain the test setups that validate our hardware and firmware, and work closely with Power Electronics, Firmware, EMC/Compliance and Mechanical engineers to track down and resolve issues.\nIt is a unique opportunity to shape the test strategy of a breakthrough power electronics platform from an early stage - with direct visibility to the CTO and engineering leadership.\nKey Responsibilities\nDesign and execute test plans for our AC/DC and DC/DC power conversion systems - functional tests, stability tests, endurance (soak) tests, and load tests.\nBuild and maintain test setups for prototype, pilot and production units, including medium-voltage test benches.\nSupport prototype validation and target-parameter verification (form factor, efficiency, stability) for our Prototype milestone.\nSupport qualification testing for Alpha customer deployments - full target-parameter verification, certification test support, and release tests for volume delivery.\nDevelop test automation scripts and tools to increase test coverage and reduce manual test effort.\nCollaborate with the Power Electronics, Firmware, EMC/Compliance and Mechanical teams to diagnose and root-cause test failures.\nDocument test procedures, results and reports; maintain traceability for certification and quality purposes.\nSupport the definition and specification of end-of-line (EOL) test equipment for volume production, working with our EOL test equipment vendor.\nSupport field testing and diagnostics for units deployed at customer sites as needed.\nQualifications\nBSc / MSc in electrical engineering, electronics engineer (Elektroniker EFZ), automation engineer (Automatiker EFZ) or comparable education.\n3+ years of experience in test engineering, ideally for power electronics or medium-voltage systems.\nExperience with medium-voltage high-power test setups and lab safety protocols and practices.\nFamiliarity with test automation and scripting (e.g. Python, LabVIEW or similar).\nUnderstanding of power electronics test methods (efficiency, thermal, load and stability testing).\nStrong documentation and analytical skills.\nTeam player, comfortable working hands-on in the lab with cross-functional teams.\nLanguage skills: fluent in English, spoken and written; German language skills helpful, but not mandatory.\nThe job will be located at our HQ in Egg b. Zürich, Switzerland.\nBenefits\nEquity + competitive salary.\nUnique technology and market opportunity - validated prototype and first paying customers on the path to volume shipments.\nHybrid work with flexible working times.","description_format":"text","description_chars":3191,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"German","level":"All levels","optional":false},{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Equity","Flexible schedule","Hybrid work"],"hiring_locations":[{"name":"Switzerland","iso":"CH","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Servers & Data Center Hardware","Power Supplies & Power Electronics"],"lifecycle":[{"event":"open","at":"2026-10-22T15:08:46Z"}],"visa":[],"liveness":{"score":31,"band":"fade","label":"Fading","p_open":1,"p_active":0.562,"p_room":0.55,"age_days":38,"expected_fill_days":29,"reasons":["conf:1","win:tail"],"computed_at":"2026-10-25T05:49:26Z"},"pay":null,"html_url":"https://alion.io/job/hyperscale-power-ag-test-engineer","json_url":"https://alion.io/job/hyperscale-power-ag-test-engineer.json","meta":{"generated_at":"2026-10-25T07:05:35Z","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":9976,"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":3786767},"rest":"https://alion.io/mcp/rest/get_company?id=3786767"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhyperscale-power-ag-test-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%2Fhyperscale-power-ag-test-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%2Fhyperscale-power-ag-test-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/hyperscale-power-ag-test-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhyperscale-power-ag-test-engineer"}]}
