Job description

About Revel

At Revel, we are revolutionizing the way the world’s most critical hardware is controlled—across aerospace, automotive, energy, and manufacturing sectors. Our next-generation software stack combines an intuitive command/control interface, a specialized programming language tailored for hardware control, and a high-performance runtime environment. We empower engineers to build, test, and deploy critical systems rapidly, reliably, and safely.

The Internship

As a Software Engineering – Test Intern at Revel, you’ll help build the infrastructure that allows us to continuously test software against real and simulated hardware.

You’ll work at the intersection of software engineering, hardware, and infrastructure, helping build and maintain Hardware-in-the-Loop (HIL) test systems and the automation that powers them. You’ll write Python, work with CI/CD systems, interact with test equipment and hardware, and help make our testing faster, more reliable, and more scalable.

This is a hands-on internship for students who enjoy figuring out how systems work, automating repetitive processes, and solving problems that span software and hardware. You’ll work closely with experienced engineers and gain exposure to the infrastructure behind software used to control mission-critical hardware.
