Senior Principal Engineer, Security Architect (2026- 346)
Location: San Jose, CA
Role Overview
Astera Labs is building the connectivity backbone of the AI era, and the platforms we ship power the world's largest AI clusters. As Senior Principal Engineer, Security Architect, you'll be the most senior technical authority defining how security is designed into everything we build — from silicon and firmware to the cloud services, tools, and enterprise systems that support them.
This is a hands-on, deeply technical architect role for someone who wants to shape security at a hyper-growth semiconductor company enabling rack-scale AI infrastructure. You'll set architectural direction, drive threat modeling and secure-by-design reviews across product and IT, and partner with engineering, product security, GRC, and IT leadership to raise the security bar in a fast-moving environment.
