Platform Applications Engineer Intern/Co-op (Tools Development Engineer – COSMOS Platform Software)

At Astera Labs, we design cutting-edge connectivity solutions that power the world’s largest cloud service providers, server manufacturers, and networking OEMs.

As a Tools Development Engineer Co-op, you will help shape COSMOS, Astera Labs’ unified software platform for monitoring, managing, debugging, and validating connectivity products. You will build the tools that customers and engineers use to configure devices, collect telemetry, investigate issues, validate behavior, and improve developer productivity.

This role sits at the intersection of software, hardware, and systems engineering. You may contribute to intuitive desktop applications, command-line utilities, automation frameworks, SDK integrations, and supporting infrastructure. You will work with experienced engineers to solve complex problems that bridge applications, systems, and silicon.

If you enjoy building high-quality software, learning how hardware and software work together, and creating tools that make engineering workflows more effective, we’d love to hear from you.
