Commissioning Specialist (Mechanical)
At Critical CxE, we don’t just commission systems—we help bring to life the infrastructure that powers the digital world. From hyperscale data centers to complex, mission-critical environments, our work ensures that the systems people rely on every day operate seamlessly.
This is more than just a role—it’s an opportunity to grow within a meaningful career. You’ll work on cutting-edge projects, gain hands-on experience at an accelerated pace, and collaborate with a high-performing team that takes pride in what they build. Along the way, you’ll develop a skillset that’s not only valuable, but in high demand across the industry.
If you’re someone who’s driven, curious, good at solving problems, and excited to be part of a growing field that truly makes an impact, we’d love to connect with you.
Why Critical CxE
At Critical CxE, we do things a little differently. You’ll grow quickly, gaining in months the kind of experience that can take years elsewhere—while working hands-on in the field, and not from sitting on the sidelines. Our team takes on high-impact, mission-critical projects, and we’re committed to supporting each other and investing in our people along the way. We have built our own internal training program that incorporates classroom training, a mentor program, and on the job immersive training. You can’t major in commissioning in school or college, and we help fill the gap by expanding your base knowledge and incorporating the commissioning process. We work everywhere, with opportunities to travel across the U.S., you’ll get to see and be part of a wide range of exciting projects both nationally and internationally.
