Opportunity Overview

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

All About You

We seek individuals who share our passion and determination. Our commitment to customer success drives us to go the extra mile. If you are ready to join us in this mission, take a closer look at the minimum criteria for the position.

• 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, Solid Works 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

Preferred

• Experience with semiconductor test equipment, high-density electronics, or capital equipment
• Experience with cooling distribution hardware, liquid-cooled platform architecture, custom fluid connectors, or thermal design verification
• Experience with printed circuit board tools such as Circuit Works or Allegro
• Experience correlating thermal models to experimental test data
• Familiarity with SEMI standards
