Thermal Mechanical Engineer (Teradyne, Agoura Hills, CA)

Thermal Mechanical Engineer Teradyne is expanding its centralized mechanical engineering capability in Agoura Hills to support next-generation semiconductor test equipment. This team partners across product development to solve complex mechanical and thermal challenges in high-performance capital equipment, from concept development through integration, verification, and release. As a Thermal Mechanical Engineer, you will own thermal design recommendations, model-to-test correlation, liquid cooling trade-offs, design verification, and closure of thermal risks for complex semiconductor capital equipment. This is a career-level role for an engineer who wants meaningful technical ownership across design, analysis, prototype, integration, and validation work. Own thermal analysis and validation plans for assigned components or subsystems Develop board-level and system-level cooling solutions for next-generation semiconductor test equipment Evaluate liquid cooling architectures, cold plates, heatsinks, fluid connectors, and related thermal-mechanical hardware Perform thermal analysis, liquid cooling analysis, and CFD modeling to support design decisions Correlate simulation results with experimental test data and translate findings into clear design recommendations Lead design reviews for assigned scope and drive closure of thermal risks, action items, and verification gaps Collaborate with suppliers and cross-functional teams on manufacturable thermal-mechanical solutions Bachelor's degree in Mechanical Engineering or related discipline with typically 5+ years of relevant experience, or Master's degree with typically 3+ years of relevant experience Strong experience with board-level thermal analysis, liquid cooling, cold plates, and thermal-mechanical design Experience using thermal or CFD tools such as Flotherm, SolidWorks Flow Simulation, or similar tools Experience with liquid delivery systems such as pumps, filters, piping, fittings, and cooling loops Proficiency with SOLIDWORKS and PDM or similar engineering data management systems Ability to independently solve engineering problems, make sound design trade-offs, and communicate recommendations clearly Strong written and verbal communication skills, including design reviews, technical reports, and cross-functional presentations Proactive, hands-on mindset with the ability to take ownership of assigned work and collaborate effectively across engineering teams Success in this role means driving assigned thermal scope to closure, making clear design recommendations, managing technical risks, and improving the quality and speed of platform-level engineering execution. The successful candidate will connect analysis, testing, supplier input, and design reviews into practical engineering decisions. This role offers the opportunity to take ownership of meaningful thermal design work within an expanding centralized engineering group supporting advanced semiconductor test platforms. The successful candidate will help improve platform capability, support design verification, influence thermal design approaches, and grow as a technical leader in a high-impact industry.
