Field Service Engineer (EM)

About the Role

As a Field Service Engineer at Thermo Fisher Scientific, you will support the installation, maintenance, and repair of sophisticated electron microscopy and analytical instrumentation. You will work with advanced technologies while delivering exceptional technical service to customers across semiconductor, research institutions, universities, government laboratories, and industrial facilities. In this role, you will troubleshoot complex systems, conduct preventive maintenance, and ensure instrumentation operates at optimal performance. Field Service Engineers work closely with customers and internal engineering teams to maintain system reliability and support scientific discovery. Depending on experience level, responsibilities may include independent troubleshooting, complex system installations, mentoring other engineers, and serving as a technical escalation point within the service organization.

Opportunities are available across multiple levels (Field Service Engineer I, II, and III) with site-based opportunities in Fremont, CA. Level placement will depend on education, technical expertise, and years of experience.

Key Responsibilities

• Install, maintain, repair, and calibrate electron microscopy systems, including:
• Scanning Electron Microscopes (SEM)
• Transmission Electron Microscopes (TEM)
• Focused Ion Beam (FIB) systems
• Conduct scheduled preventive maintenance to ensure optimal system performance.
• Troubleshoot and diagnose complex system issues involving electronics, vacuum systems, high voltage components, and integrated software.
• Provide technical support to customers and collaborate with other field service engineers to resolve service challenges.
• Develop strong relationships with customers while ensuring high levels of customer satisfaction and system uptime.
• Travel to customer sites to install equipment, perform repairs, and support system operation.
• Document service activities and submit detailed field service reports.
• Provide training and technical guidance to customers on system operation and maintenance.
• Follow all safety procedures and quality standards while servicing equipment in laboratory environments.
• Provide feedback to engineering, product quality, and service leadership teams to support continuous product improvement.
• Support updates to technical documentation and service procedures.
• For more experienced levels, responsibilities may include mentoring junior engineers, leading complex installations, and serving as a technical escalation resource.
