Principal Product Applications Engineer

Astera Labs is a global leader in purpose-built connectivity solutions that unlock the full potential of cloud and AI infrastructure. Our Intelligent Connectivity Platform integrates PCIe, CXL and Ethernet semiconductor-based solutions based on a software-defined architecture that is both scalable and customizable. Inspired by trusted partnerships with hyperscalers and the data center ecosystem, we are an innovation leader with products that are flexible, interoperable, and reliable. We are headquartered in the heart of California’s Silicon Valley, with R&D centers and offices in Texas, Taiwan, China, Canada, and Israel. 

As an Astera Labs Product Applications Engineer, you will be part of a team that supports design-in of Astera Labs’ portfolio of connectivity products by the world’s leading cloud service providers and server and network OEMs. In this role, you will need to provide technical guidance to customers to overcome design challenges, generate collateral for existing and new products, and drive innovation by providing insightful feedback to other internal teams to continuously improve products and processes. You will investigate and duplicate issues reported by customers, and drive critical issues to resolution. There are opportunities to support key customers directly, and also to dive deep in the lab to address the challenges associated with leading edge semiconductor products.
