Sr. Principal Systems / Rack SW Architect (OpenBMC/Redfish/Cosmos)

Astera Labs is at the epicenter of the AI infrastructure revolution, building the intelligent connectivity solutions that power the world's most advanced data centers. As AI workloads scale to unprecedented levels, the demand for purpose-built, rack-scale platforms that seamlessly integrate high-speed connectivity, firmware intelligence, and composable architectures has never been greater — and neither has the opportunity to shape what comes next.

The AI Platform Solutions Group is seeking a Sr. Principal Systems/Rack SW Architect to serve as the technical visionary for next-generation AI infrastructure, spanning server firmware, high-speed connectivity, and rack-scale system design. In this role, you will define the end-to-end architecture for AI platforms that integrate cutting-edge technologies such as PCIe Gen5/6, UAlink, CXL, composable rack architectures, and advanced interconnect solutions including Astera Labs' portfolio of retimers, switches, and fabric controllers.

This is a high-impact, high-visibility role where you will drive innovation across silicon integration, platform firmware, system performance, and rack-level orchestration — directly enabling hyperscale AI training and inference workloads. You will partner with silicon vendors, hyperscalers, OEMs, and ODMs while influencing industry standards and mentoring the next generation of platform architects. If you want to architect the future of AI infrastructure at a company that is defining the connectivity backbone of modern data centers, this is your role.
