Staff Security Architect

If you'd like to build the world's best AI cloud, join us.

*Note: This position requires presence in our Bellevue, San Francisco, or San Jose office location 4 days per week; Lambda’s designated work from home day is currently Tuesday.

Lambda Security protects some of the world's most valuable digital assets: invaluable training data, model weights representing immense computational investments, and the sensitive inputs required to leverage best of breed AI models. We're responsible for securing every byte that powers breakthrough artificial intelligence.

Reporting to the CISO, you'll be a principal technical leader responsible for shaping Lambda's overall security architecture, with a primary focus on Data Protection and Platform Security. Your work will define secure-by-default foundational patterns across our core AI infrastructure, hardware/GPU platform layers, multi-cloud control planes, and end-to-end data lifecycles.

You will directly impact the security posture of our high-performance computing environment by architecting robust data loss prevention (DLP), encryption at rest and in transit, key management (KMS/HSM), confidential computing, and tenant isolation models. Leveraging Lambda's hosted LLMs, you'll pioneer AI-driven security architecture capabilities—such as automated threat modeling, sensitive data discovery, and platform policy verification.
