Cohu is seeking a highly motivated Mechanical Engineer to design and develop precision electro-mechanical systems for semiconductor automated test equipment platforms, with a strong focus on mechanical integration of PCBs. The ideal candidate has hands-on experience in precision mechanical assemblies, PCB support structures, and system-level design, supporting products from concept through production.


Key Responsibilities

  • Lead mechanical design for PCB assemblies, including component mounting, board support structures, thermal management, and integration within test equipment.
  • Design precision electro-mechanical systems such as motion mechanisms, structural components, and enclosures.
  • Develop 3D CAD models, detailed drawings, tolerance analyses, and BOMs for mechanical and PCB components.
  • Support system integration, verification, and qualification testing during new product development.
  • Perform structural and thermal analysis using FEA and CFD tools, including thermal validation for PCB assemblies.
  • Investigate failures and implement corrective design actions.
  • Support mechanical integration of semiconductor test cells, including tester interfaces, device handlers, and manipulators.
  • Collaborate with hardware and applications teams to ensure system-level and PCB-level performance.
  • Work with Manufacturing and Supply Chain on vendor selection, part qualification, and cost optimization.
  • Document designs, changes, and engineering updates using standard processes.

Required Qualifications

  • BS in Mechanical Engineering (MS preferred).
  • Minimum 5 years of experience designing electro-mechanical systems or capital equipment.
  • Strong hands-on experience in precision mechanical assemblies and PCB support structures.
  • Proficiency with 3D CAD software (SolidWorks, Creo) and GD&T.
  • Experience with FEA and/or CFD analysis tools.
  • Knowledge of mechanical integration in complex systems, including PCB design, EMN creation, thermal management, DFM/DFA, and interconnect systems.
  • Familiarity with Agile development, Oracle PLM systems, and cross-functional collaboration for system and PCB integration.
  • Experience supporting products through development and production cycles.
  • Electromechanical applications experience in semiconductor or related industries.

Preferred Experience

  • Semiconductor equipment or automated handling/test systems.
  • Experience with suppliers and manufacturing teams.
  • Exposure to motion systems, thermal management, electronic packaging, or PCB-level mechanical integration.

What you need to know about the Boston Tech Scene

Boston is a powerhouse for technology innovation thanks to world-class research universities like MIT and Harvard and a robust pipeline of venture capital investment. Host to the first telephone call and one of the first general-purpose computers ever put into use, Boston is now a hub for biotechnology, robotics and artificial intelligence — though it’s also home to several B2B software giants. So it’s no surprise that the city consistently ranks among the greatest startup ecosystems in the world.

Key Facts About Boston Tech

  • Number of Tech Workers: 269,000; 9.4% of overall workforce (2024 CompTIA survey)
  • Major Tech Employers: Thermo Fisher Scientific, Toast, Klaviyo, HubSpot, DraftKings
  • Key Industries: Artificial intelligence, biotechnology, robotics, software, aerospace
  • Funding Landscape: $15.7 billion in venture capital funding in 2024 (Pitchbook)
  • Notable Investors: Summit Partners, Volition Capital, Bain Capital Ventures, MassVentures, Highland Capital Partners
  • Research Centers and Universities: MIT, Harvard University, Boston College, Tufts University, Boston University, Northeastern University, Smithsonian Astrophysical Observatory, National Bureau of Economic Research, Broad Institute, Lowell Center for Space Science & Technology, National Emerging Infectious Diseases Laboratories
