Field Service Engineer Semiconductor Jobs in Massachusetts

Summary: We are seeking an experienced Senior Field Service Engineer to support, troubleshoot, and maintain vacuum environment robotic systems deployed in semiconductor manufacturing equipment. This role requires expert level mechanical and electronic systems troubleshooting capability, familiarity with semiconductor fabrication environments, and the ability to analyze and diagnose complex operational issues in robots and their sub-systems. The ideal candidate will communicate complex technical issues clearly and concisely through written reports, schematics, and verbal briefings to various stake holders.

The ideal candidate excels in customer-facing environments, manages escalations with clarity and urgency, and collaborates cross‑functionally with engineering, applications, quality, and service teams. This position also requires the ability to write, review, and deliver high‑quality root-cause, 5-Whys and corrective actions reports based on forensic teardown of RMA systems. Frequent domestic and international travel is required to support global semiconductor OEM and end user customers. This role bridges service, engineering, quality, manufacturing, suppliers, and internal/external stakeholders to start from ambiguous failures in remotely located robotic systems and end at actionable, data-backed conclusions.

• Familiarity with structured problemsolving methodologies (8D, 5‑Why, Ishikawa).
• Experience supporting high‑volume manufacturing environments.
Experience Required:
• 5+ years of field service experience supporting semiconductor equipment, robotics, automation, or high‑precision electromechanical systems.
Other Requirements:
• Required approx. 40% travel includes local, domestic and international location
• Work is sedentary in nature, but may require standing, walking, grasping, and lifting/moving up to 25 pounds
Education Required:
• Bachelor’s degree in Robotics Engineering, Electrical engineering, Mechanical Engineering, Mechatronics, Engineering Technology, or related technical fields.
