Test Engineer

ppHyperscale 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. /ppAs 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. /ppIt 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. /ph3Key Responsibilities /h3ulliDesign and execute test plans for our AC/DC and DC/DC power conversion systems – functional tests, stability tests, endurance (soak) tests, and load tests. /liliBuild and maintain test setups for prototype, pilot and production units, including medium-voltage test benches. /liliSupport prototype validation and target-parameter verification (form factor, efficiency, stability) for our Prototype milestone. /liliSupport qualification testing for Alpha customer deployments – full target-parameter verification, certification test support, and release tests for volume delivery. /liliDevelop test automation scripts and tools to increase test coverage and reduce manual test effort. /liliCollaborate with the Power Electronics, Firmware, EMC/Compliance and Mechanical teams to diagnose and root-cause test failures. /liliDocument test procedures, results and reports; maintain traceability for certification and quality purposes. /liliSupport the definition and specification of end-of-line (EOL) test equipment for volume production, working with our EOL test equipment vendor. /liliSupport field testing and diagnostics for units deployed at customer sites as needed. /li /ulh3Qualifications /h3ulliBSc / MSc in electrical engineering or comparable education. /lili3+ years of experience in test engineering, ideally for power electronics or medium-voltage systems. /liliExperience with medium-voltage high-power test setups and lab safety protocols and practices. /liliFamiliarity with test automation and scripting (e.g. Python or similar). /liliUnderstanding of power electronics test methods (efficiency, thermal, load and stability testing). /liliStrong documentation and analytical skills. /liliTeam player, comfortable working hands-on in the lab with cross-functional teams. /liliLanguage skills: fluent in English, spoken and written; German language skills helpful, but not mandatory. /liliThe job will be located at our HQ in Egg b. Zürich, Switzerland. /li /ulh3Benefits /h3ulliEquity + competitive salary. /liliUnique technology and market opportunity – validated prototype and first paying customers on the path to volume shipments. /liliHybrid work with flexible working times. /li /ul /p #J-18808-Ljbffr
