Test Engineer

ph3Job Description /h3 pHyperscale Power is building the power backbone for the AI data center era: a complete power conversion chain from 13.8kV–35kV medium-voltage AC down to 800V DC, combining ultra-compact SiC-based AC/DC and DC/DC power blocks. 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. /p pAs 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. /p pIt 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. /p h3Key Responsibilities /h3 ul liDesign and execute test plans for our AC/DC and DC/DC power conversion systems – functional tests, stability tests, endurance (soak) tests, and load tests. /li liBuild and maintain test setups for prototype, pilot and production units, including medium-voltage test benches. /li liSupport prototype validation and target-parameter verification (form factor, efficiency, stability) for our Prototype milestone. /li liSupport qualification testing for Alpha customer deployments – full target-parameter verification, certification test support, and release tests for volume delivery. /li liDevelop test automation scripts and tools to increase test coverage and reduce manual test effort. /li liCollaborate with the Power Electronics, Firmware, EMC/Compliance and Mechanical teams to diagnose and root-cause test failures. /li liDocument test procedures, results and reports; maintain traceability for certification and quality purposes. /li liSupport the definition and specification of end-of-line (EOL) test equipment for volume production, working with our EOL test equipment vendor. /li liSupport field testing and diagnostics for units deployed at customer sites as needed. /li /ul h3Qualifications /h3 ul liBSc / MSc in electrical engineering or comparable education. /li li3+ years of experience in test engineering, ideally for power electronics or medium-voltage systems. /li liExperience with medium-voltage high-power test setups and lab safety protocols and practices. /li liFamiliarity with test automation and scripting (e.g. Python or similar). /li liUnderstanding of power electronics test methods (efficiency, thermal, load and stability testing). /li liStrong documentation and analytical skills. /li liTeam player, comfortable working hands-on in the lab with cross-functional teams. /li liLanguage skills: fluent in English, spoken and written; German language skills helpful, but not mandatory. /li liThe job will be located at our HQ in Egg b. Zürich, Switzerland. /li /ul h3Benefits /h3 ul liEquity + competitive salary. /li liUnique technology and market opportunity – validated prototype and first paying customers on the path to volume shipments. /li liHybrid work with flexible working times. /li /ul /p #J-18808-Ljbffr
