Senior Security Engineer - Enterprise Security

About the role

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: 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.

As a Senior Security Engineer on Enterprise Security, you'll secure Lambda as a business with people who use computers: the identities, devices, SaaS, and AI tools our employees and contractors use every day. Reporting to the Senior Manager of Security, you'll own security outcomes across the corporate environment, including systems other teams run, and solve the problems you find directly by building the controls, automation, and integrations that fix them. You'll partner with IT, HR, Legal, GRC, Detection & Response, Security Platform, and Developer Productivity.

Everything Lambda sells is built and run by our people. Securing how they work protects the business and customer data they handle and everything they build, from the code we ship to the infrastructure customers trust with their most valuable workloads. Near term, that means identity automation that keeps access matched to each person's role, secure access for contractors and personal devices, controls on where agents can send company data, and secure environments for running AI agents off laptops. You'll work with Lambda-hosted LLMs, alongside frontier models and AI tools, to take enterprise security further than traditional approaches allow.

This is a specialist security engineering role, not IT support. Lambda's people rapidly adopt frontier AI tools and agents, and making that safe is an engineering problem rather than a policy memo. If that's the problem you want to solve, we'd love 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. If you do not exactly meet this description but believe you may be a good fit, please still apply and help us understand your readiness for this role. Your application is not a waste of our time.

What You'll Do

Securing the Corporate Environment:

- Make the safe way to use AI tools and agents the easy way, with approved tools, connectors, and agent environments.

- Make sure humans, agents, and integrations move sensitive data only along reviewed paths, following Lambda's data protection strategy.
