Step into a Day on the Road

You wake up in a new city, grab your toolkit, and head straight to a customer site. By mid-morning, you’re deep into diagnostics on a Mitsubishi Sinker EDM, tracing faults across electrical and mechanical systems. After lunch, you’re rebuilding a subassembly, validating with measurements, and closing the loop with clear documentation. Before the day ends, you’re on the phone helping another customer troubleshoot remotely. That’s a typical day as our CNC Sinker EDM Service Engineer.

Role Overview

In this customer-facing role, you’ll apply advanced mechanical and electrical know-how to troubleshoot, repair, modify, and test Mitsubishi machining products. This position travels 100% of the time, Monday–Friday. Travel is primarily across the United States, with occasional international assignments. Support is delivered on-site at customer facilities and, when appropriate, via telephone. We invest in training and long-term growth, and we’re proud of our employee longevity and exceptional customer retention.
