This role blends mechanical and electrical engineering fundamentals with hands on testing and system operation in a dynamic, industrial laboratory environment. Youll plan and execute custom tests, design fixtures and methods, instrument hardware, collect high quality data, and transform results into clear, actionable insights. Battery projects span testing and analysis of cells, modules, and packs in diverse applications across various sectors. The common thread: understanding how a system is supposed to perform, and prove 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. Youre hands on, mechanically curious, and comfortable working with electrical, mechanical, and chemical systems. You can safely navigate a heavy industrial lab setting, juggle competing priorities, and keep projects moving forwardeven when tests dont go as planned. Strong communication skills are essential. Youll routinely interact with teammates and clients, translating technical details into clear verbal explanations and well written test methods and reports. Experience in battery testing, energy storage, EV systems, or other safety-critical and regulated industries 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 thats 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, youre in the lab, 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 cant be found any other way, particularly when characterizing battery thermal behavior, abuse response, or failure mechanisms. Throughout the day, you balance safety, schedule, and performance while managing risk in real time. By days end, you can see tangible progress: data collected, questions answered, and another complex test successfully executed. Its hands-on, fast paced, occasionally chaotic, and deeply satisfying work that keeps Test Engineers at SES excited to come back every day.
