Description At Affiliated Engineers, Inc. (AEI), we design engineering systems that drive discovery, heal communities, fuel innovation, and shape a more sustainable world. Since 1978, we’ve supported mission-driven clients across healthcare, science and technology, energy and utilities, higher education, government, and other vital sectors in bringing their most ambitious goals to life through engineering excellence.

What began as a small firm serving schools and churches has organically grown into one of the nation’s top-ranked engineering companies, with 1,000 skilled professionals in 23 offices nationwide. Our reach is national, but our approach is personal, tailored to each client and project, grounded in collaboration, humility, and an unwavering commitment to quality. As our clients’ needs have evolved, so have our services. Today, we offer integrated expertise in mechanical, electrical, plumbing/piping, and fire protection engineering, along with commissioning, security, building performance, architectural lighting design through our in-house studio, Pivotal Lighting Design, and more.

Our work is complex, and the stakes are high—but that’s where we thrive. AEI teams solve tough challenges with creativity, precision, and purpose. From net-zero energy laboratories and next-generation hospitals to resilient energy systems and secure federal facilities, we design the infrastructure that helps move society forward.

And just as we champion our client’s success, we invest deeply in our people because their growth powers our progress.

At AEI, you’ll find more than a job—you’ll find a career with an impact. We empower employees at every level to lead, grow, and thrive. That means meaningful project work, mentorship from industry-recognized experts, and a culture that celebrates curiosity, accountability, and progress. We recognize achievements, encourage professional development, and open doors to advancement—all within a community built on trust, respect, and shared success.

You’ll work alongside passionate, driven colleagues who care deeply about their craft and even more about each other. Together, we’re not just engineering systems—we’re engineering a better future. Join us!
