Jobs at Cohu, Inc.

Lead system-level development of complex mechatronic systems, particularly for semiconductor backend equipment. Design subsystem architectures, validate feasibility through analytical modeling and simulation, and guide interdisciplinary teams through design reviews and trade-off decisions. Ensure architectural consistency, compliance with certification standards (CE, SEMI, RoHS), and drive risk assessments and technology validation activities. Requires 3+ years of systems engineering leadership plus 3+ years as a direct engineer, with expertise in thermal systems, motion control, sensor integration, and proficiency in Solidworks, MATLAB/Simulink, and CAE tools.

Lead system-level engineering for complex electro-mechanical and robotic modules, translating customer requirements into multi-disciplinary designs that balance performance, reliability, and cost. Drive cross-functional concept development, conduct requirement analysis, and author technical specifications for automated sub-assemblies. Evaluate feasibility through analytical modeling and simulation, ensure architectural consistency across subsystems, and guide design reviews while managing risk assessments and compliance certification (CE, SEMI, RoHS). Requires minimum 3 years of system-level leadership on mechatronic systems development, preferably in semiconductor backend equipment, with proficiency in Solidworks or equivalent CAD tools.

This role provides IT risk management and cybersecurity oversight for a large, multi-location enterprise environment. Key responsibilities include triaging security alerts and IOCs, conducting IT security audits (network, OS, data center), administering Microsoft 365 Defender for Cloud and endpoint protection platforms, managing vulnerability assessments, and assisting with cloud migrations to Azure and Microsoft 365 services. The role requires 5+ years of IT experience in large environments, IT audit experience, Security+ or Cloud+ certification, and hands-on administration of Active Directory, SIEM tools, and service-desk ticketing systems.

Design, develop, and sustain Windows desktop control software for complex electro-mechanical semiconductor test handlers using C++ and C#. Responsibilities span full lifecycle development—architecture, integration, deployment, and customer support—with focus on system uptime, safety, and reliability. Own hardware integration (motion controllers, machine vision, robotics, sensors, barcode readers), troubleshoot field issues, and drive system architecture across product variants. Mentor engineers and collaborate cross-functionally with manufacturing, field service, and customer teams.
