Senior Field Service Engineer

As a Senior Field Service Engineer, you travel to customer sites to install, maintain, repair, and upgrade complex equipment. You represent both the product and the company — your technical competence and professionalism directly influence customer satisfaction and retention. The senior title means you handle the most critical and complex service calls, mentor junior engineers, and often serve as the escalation point when standard troubleshooting fails.

Your day revolves around solving customer problems on-site. You might fly to a semiconductor fab to repair a metrology tool, then drive to another customer to perform a scheduled preventive maintenance, then call in to help a junior engineer troubleshoot remotely. You need deep product knowledge, strong diagnostic skills, and the customer-facing demeanor to remain calm and professional when equipment is down and the customer is frustrated.

The critical skill beyond technical ability is managing customer expectations. When a production-critical tool goes down, the customer wants it fixed immediately. Sometimes that's possible; sometimes parts need to be ordered. Communicating honestly about timelines while demonstrating urgency is what separates senior field service engineers from junior ones.
