About the Role

~1 min read

Astera Labs is looking for a Principal Product Applications Engineer to support the deployment of our Leo Smart Memory Controller and Extender solutions in next-generation server, AI, and datacenter platforms.

This role sits at the intersection of memory architecture, system integration, hardware/software debug, and customer engineering. You will work directly with customers and Astera Labs engineering teams to bring up platforms, troubleshoot complex memory and system issues, support product development, and drive solutions from initial integration through production.

We are looking for an experienced engineer with strong DDR/DRAM and memory subsystem expertise who enjoys solving complex system-level problems and working with customers. Experience with CXL and related high-speed technologies is highly relevant. Firmware or platform software experience is valuable, but not required.
