The Role
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.
Key responsibilities include:
Developing custom and specialized test plans, fixtures, and test methods
Executing tests safely and efficiently while monitoring live data
Collecting, analyzing, and documenting high‑quality test data
Interpreting results and producing clear, concise technical reports
What Success Looks Like
Successful Test Engineers at Stress are adaptable problem solvers who thrive in both independent and collaborative environments. You’re hands‑on, mechanically curious, and comfortable working with electro‑mechanical systems, instrumentation, and multiple sensor types. You can safely navigate a heavy industrial lab setting, juggle competing priorities, and keep projects moving forward— even when tests don’t go as planned.
Strong communication skills are essential. You’ll routinely interact with teammates and clients, translating technical details into clear verbal explanations and well‑written test methods and reports. Experience in regulated industries (medical device, pharmaceutical, aerospace, etc.) is a plus. Depending on your experience, you may also take the lead on managing projects, interfacing directly with clients, and guiding the work of other engineers and technicians.
SES Core Values
We Over Me
– We put the mission, our clients, and our team ahead of individual agendas.
Unyielding Pursuit of Excellence
– Excellence is the standard. We deliver the right solution, on time, every time.
Own It
– We take personal and collective accountability to earn trust and deliver results.
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.
Basic Qualifications
BS in Mechanical Engineering with 3–5 years of experience in testing or manufacturing/industrial equipment operations
Experience with mechanical testing methods and instrumentation
Hands‑on aptitude and comfort working with physical systems
Experience with data acquisition and test control systems
Ability to conceptualize and develop test methods, fixtures, and equipment with attention to accuracy and repeatability
Strong technical writing and communication skills
Highly motivated, self‑starter with strong critical thinking and problem‑solving abilities
Familiarity with statistical techniques for reliability, capability analysis, regression, ANOVA, and sample size justification (plus)
Experience with CAD software (SolidWorks or similar)
Professional Engineer license or willingness to obtain one
Preferred Qualifications
MS in Engineering or more than 5 years of relevant experience
Knowledge of material properties and failure mechanisms for metals and polymers under mechanical, thermal, and environmental loading
Experience developing test plans and reports suitable for verification and regulatory submissions
Experience validating test methods for repeatability and reproducibility
Familiarity with hazard and risk assessment tools such as FMEA or fault tree analysis
Experience with U.S. and EU medical device regulations
Experience or familiarity with finite element analysis
