Senior Security Engineer - Enterprise Security

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers. Our customers range from AI researchers to enterprises and hyperscalers. Lambda's mission is to make compute as ubiquitous as electricity and give everyone the power of superintelligence. One person, one GPU.

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.

About the Role

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 key member of the Enterprise Security team responsible for securing Lambda's SaaS applications, corporate IT infrastructure, identity and access management (IAM), and endpoint ecosystems. Your work will focus on establishing secure-by-default configurations, automating access governance, and protecting corporate environments as Lambda scales rapidly.

You will directly impact the security posture of our enterprise operations by implementing robust Identity Governance and Administration (IGA), hardening corporate SaaS tools, automating joiner-mover-leaver (JML) workflows, and deploying zero-trust network access controls. Leveraging Lambda's hosted LLMs, you'll pioneer AI-driven enterprise security automation—such as intelligent access reviews, automated policy enforcement, and SaaS risk monitoring.

If you're excited about building enterprise security controls that balance strong protection with developer and employee productivity, we want to talk.

We value diverse backgrounds, experiences, and skills, and we are excited to hear from candidates who can bring unique perspectives to our team.

Governance & Cross-Functional Alignment

Collaborate with IT, Legal, HR, and Compliance teams to ensure corporate systems align with frameworks such as SOC 2, ISO 27001, and HIPAA

Establish internal security documentation, end-user security awareness guidelines, and self-service security options for employees

Define strategic roadmap initiatives for corporate security, driving measurable security posture improvements across all business units
