Principal/Senior Engineer – Test Engineering & Technical Operations

About the role

At AUMOVIO AESS, we are building the next generation of automotive semiconductor solutions that enable safer, smarter, and more connected mobility. We are looking for a highly motivated Principal / Senior Test Engineer to join our growing Technical Operations Management (TOM) organization. The role will drive test engineering excellence from new product introduction (NPI) through high‑volume manufacturing, ensuring automotive‑grade quality, reliability, manufacturability, and cost targets.

Key responsibilities

• Lead transfer of wafer sort (CP), burn‑in, and final test (FT) solutions from R&D into manufacturing.
• Debug, qualify, release and sustain ATE test programs for volume production.
• Support silicon bring‑up, characterization, correlation, and production validation.
• Drive test coverage optimization, multi‑site efficiency, test time reduction, and manufacturing readiness.
• Qualify and maintain test hardware including probe cards, load boards, burn‑in boards, and sockets.
• Serve as the technical focal point for OSAT test and burn‑in operations.
• Support qualification builds, product ramp‑up, manufacturing transfers and sustaining activities.
• Collaborate with OSATs and suppliers to resolve testing‑related technical and production issues.
• Drive manufacturing yield, quality, productivity and operational excellence.
• Work closely with Product Engineering on characterization, qualification, yield improvement, and production release.
• Define test limits, screening strategies and production release criteria.
• Support NPI, reliability qualification, and product change management activities.
• Drive data‑driven decisions to improve product quality and manufacturability.

Required profile

• Bachelor's, Master's, or PhD in Electrical Engineering, Electronics Engineering or related field.
• Minimum 5+ years (Senior Engineer) or 8+ years (Principal Engineer) of semiconductor industry experience in Test Engineering or Product Engineering.
• Experience in product testing solutions development (ATE SW and HW, Burn‑In) and release for high‑volume production with OSAT is highly preferred.
• Experience in managing product test operation with OSAT.
• Self‑motivated, hands‑on team player with a strong ownership mindset, capable of delivering results in a dynamic and rapidly growing startup environment.
• Strong collaboration, communication, and interpersonal skills, with the ability to work effectively across global and multicultural teams.
• Excellent analytical and problem‑solving skills, combining data‑driven decision‑making with sound engineering judgment.

Required skills

• Hands‑on experience in ATE test development, debug, characterization, qualification, and production release for Wafer Sort, Burn‑In, and Final Test.
• Strong knowledge of Advantest V93000 (V93K) SmarTest platform and test program development.
• Experience in test hardware development, including Probe Cards, Load Boards, and Burn‑In Boards.
• Expertise in silicon characterization, correlation, shmoo analysis, yield improvement, and failure analysis.
• Experience with OSAT qualification, production ramp‑up, and high‑volume manufacturing operations.
• Proven capability in test coverage optimization, test time reduction, and cost improvement.
• Strong skills in test data analytics and statistical methods.
