About The Position

As a Test Engineer at SES, you’ll turn complex questions into meaningful data. This role blends mechanical engineering fundamentals with hands-on testing and system operation in a dynamic, industrial laboratory environment. You’ll plan and execute custom tests, design fixtures and methods, instrument hardware, collect high-quality data, and transform results into clear, actionable insights. Projects span medical devices, consumer products, primary and tertiary packaging, mechanical and electrical systems, industrial processes, and engineering materials. The common thread: understanding how a system is supposed to perform—and proving whether it actually does. A Day in the Life No two days are the same—and that’s exactly what makes this role rewarding. Your morning might start with a technical discussion alongside engineers, technicians, and clients, refining a test concept or identifying instrumentation and risk considerations. You may review drawings, finalize a test plan, or troubleshoot an unexpected challenge that requires creative thinking and mechanical intuition. Before long, you’re in the lab or test yard—instrumenting hardware, coordinating with technicians, monitoring live data, and adapting on the fly. Sometimes that means pushing systems to their limits— breaking them, or even blowing them up (intentionally) to uncover answers that simply can’t be found any other way. Throughout the day, you balance safety, schedule, and performance while managing risk in real time. By day’s end, you can see tangible progress: data collected, questions answered, and another complex test successfully executed. It’s hands-on, fast-paced, occasionally chaotic—and deeply satisfying work that keeps Test Engineers at SES excited to come back every day.
