What are the responsibilities and job description for the Battery Testing Intern position at Stress Engineering Services, Inc.?
Have I ever wanted to work hands-on with real battery systems and see how they perform under extreme conditions?
Do you want to learn from experienced engineers while contributing to projects that impact safety, performance, and reliability?
Ever wondered what really happens inside a battery when it’s pushed to the limit? This is your chance to find out.
We’re looking for a curious, hands-on Battery Testing Intern who’s ready to step into the lab and help test, challenge, and validate next-generation battery technologies. In this role, you won’t just observe, you’ll be actively involved in real testing that impacts product safety, performance, and reliability.
At Stress Engineering Services, we are a passionate, multidisciplinary team of expert problem solvers dedicated to tackling the toughest engineering challenges. Since 1972, we have delivered innovative, forward-thinking solutions for clients who demand deep technical expertise and proven performance across engineering design and analysis, thermal and fluid sciences, instrumentation, and testing. Our work pushes boundaries, elevates how businesses operate, and delivers measurable impact across industries worldwide. It’s no surprise that SES has often been described as the “Disneyland for Engineers”, a place where challenging ideas become real-world engineering achievements.
What truly sets us apart is our people and our purpose. At SES, we combine advanced technology, creative thinking, and rigorous engineering fundamentals within a culture built on trust, excellence, and integrity. We are committed to developing and delivering emerging concepts with the highest standards of service—empowering our engineers to collaborate, grow, and make a meaningful difference. If you’re driven by complex problems, energized by hands-on innovation, and inspired by work that’s as exciting as it is impactful, you’ll find your place here.
Why This Internship?
Batteries power everything, vehicles, grid storage, consumer electronics, and emerging clean-energy technologies. Before they ever reach the real world, they must survive extreme conditions. Thats where testing comes in.
As a Battery Testing Intern, you’ll work at the intersection of performance, safety, and innovation, helping push batteries to their limits to ensure they can handle heat, abuse, and long-term use. This is a hands-on, lab-based role where your work directly supports safer, more reliable energy solutions.This internship offers hands-on experience working with real-world battery technologies in a laboratory and engineering environment. The ideal candidate is curious, detail-oriented, and eager to learn about battery performance, safety, and reliability.
What You’ll Do
This internship puts you inside the test lab, working alongside engineers to evaluate how batteries respond to real-world and worst-case conditions.
