Product Qualification Engineer (f/m/d)

We are seeking a Product Qualification Engineer to join our team. In this role, you will execute product qualification activities, turning qualification plans into robust test setups, reliable bench data, and clear, traceable evidence that supports product release.

• Run product qualification testing by performing bench and laboratory qualification tests (thermal, electrical, mechanical, and environmental stress tests) in accordance with qualification plans and test matrix, while accurately tracking samples, test conditions, and results.
• Develop test PCBs and fixtures with external partners, work on test boards, adapters, and fixtures, from requirements through review and bring-up.
• Set up and maintain qualification test equipment, including thermal chambers, power supplies, data acquisition systems (DAQ), probe stations, and other laboratory instrumentation, ensuring the lab is always ready to support qualification activities.
• Coordinate qualification campaigns with OSATs and external laboratories by managing schedules, sample logistics, and test execution, while providing on-site or remote test supervision where needed
• Collect, analyze, and document qualification results, producing clear pass/fail assessments, comprehensive test reports, and fully traceable records that contribute to the overall product qualification evidence package.
• Identify and communicate risks early, proactively escalating test failures, equipment limitations, data anomalies, or schedule risks to the Package Reliability Engineer and Quality & Reliability Program Lead to keep qualification activities on track.

• Educational background with a Bachelor's or Master's degree in Electrical Engineering, Electronics, or a related discipline.
• Hands-on product qualification experience with 2–4+ years of experience in hardware bring-up, bench testing, or product qualification test campaigns.
• Experience testing RF and high-speed I/O, including high-speed serial, RF, or optical links using equipment such as vector network analyzers (VNAs), high-bandwidth oscilloscopes, BERTs, and other signal integrity measurement tools. This is a core requirement for the role, as experience limited to low-speed digital or logic circuit testing is not sufficient. Experience with photonics testing is a strong advantage.
• Proficiency with laboratory test equipment, including oscilloscopes, power supplies, thermal chambers, data acquisition (DAQ) systems, and, ideally, RF and high-speed characterization equipment such as VNAs, BERT, and high-bandwidth scopes.
• Experience developing test hardware, working closely with PCB design and fabrication partners to define specs, review designs, and support the bring-up of test boards or fixtures.
• Strong test execution and documentation skills, running test campaigns methodically and writing clean, traceable results.
• Excellent collaboration and coordination skills, with experience working across reliability engineering, product engineering, external laboratories, and OSAT partners to successfully execute qualification activities.
• Thrives in a startup environment, demonstrating initiative, adaptability, and the ability to take ownership in a fast-paced, resource-conscious setting.
