About The Position

The Field Service Engineer installs, commissions, maintains, troubleshoots, and repairs advanced industrial X-ray inspection systems, including microfocus X-ray sources, high-voltage generator-based systems, and industrial linear accelerators (LINACs). These systems support non-destructive testing, metrology, aerospace, automotive, electronics inspection, industrial imaging, and other aerospace, defense, nuclear, and energy applications, including high-energy radiography and computed tomography. The role combines in-house system testing with field service at customer facilities worldwide. The engineer serves as the primary technical contact for customers, provides technical support and operator training, and helps maintain customer satisfaction. Approximately 50% travel is required, including some international travel.

Requirements

Bachelor’s degree or diploma in Electrical Engineering, Electronics Engineering, Mechatronics, Applied Physics, Biomedical Engineering, or a related technical field.
At least 5 years of experience servicing industrial X-ray systems or similar high-voltage equipment.
Experience with one or more of the following: microfocus X-ray sources, high-voltage generators (typically 90 kV–450 kV), or industrial LINAC systems.
Strong background in electronics troubleshooting and electromechanical systems.
Ability to read and interpret electrical schematics and technical drawings.
Experience using diagnostic tools such as oscilloscopes and digital multimeters.
Knowledge of radiation safety practices and regulatory compliance.
Ability to travel up to 50%, including internationally.
Ability to lift up to 25–30 kg (55–65 lbs).
Comfort working around high-voltage and radiation-generating equipment and in industrial environments and customer facilities.
