Manager - Security Architecture

Lambda, The Superintelligence Cloud, builds Gigawatt-scale AI Factories for Training and Inference. Lambda’s mission is to make compute as ubiquitous as electricity and give every person access to artificial intelligence. One person, one GPU.

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

*Note: This position requires presence in our San Francisco, San Jose, or Seattle 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 Senior Manager of Security, your team serves dual functions: building security for the business and demonstrating that work directly to customers. As security advisors to Product Engineering, Platform Engineering, and IT teams, your team will establish security policies and architecture standards, conduct threat modeling and design reviews for critical systems, and create implementation guidance that engineering teams can adopt. In support of our customers, your team will develop customer-facing security documentation and participate directly in enterprise security discussions. This work ensures the right security decisions get made across Lambda's AI infrastructure while protecting customer data, enabling hypergrowth velocity, and building the trust that closes enterprise deals.

As Manager of the Security Architecture team, you'll build and lead a team of 4-5 security engineers with expertise across application security, infrastructure security, and corporate security. You'll hire strong specialists, coach them through complex security problems, set team priorities and architectural direction, and create a culture where security judgment accelerates business velocity rather than creating friction.

Your success is measured by the security decisions your team enables across the business: engineering teams building secure-by-default systems, compliance frameworks mapped to technical controls, and customers trusting Lambda's infrastructure with their most valuable AI workloads. Your team will balance proactive architecture work (defining what "good" looks like) with reactive consultation (reviewing designs and answering complex security questions).

Your immediate focus will be building your team, establishing processes for design reviews and architecture guidance that scale with Lambda's growth, and developing a 6-12 month roadmap aligned with Lambda's 2026 security strategic plan including compliance initiatives like ISO 27001.

We're looking for engineering managers who pair strong people leadership with enough security depth to coach specialists, set architectural direction, and translate security decisions into business value. If you're energized by building high-performing teams, enabling security at scale through excellent judgment rather than brute force, and helping enterprise customers trust their most valuable AI workloads to Lambda's infrastructure, 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

Team Leadership & Development

- Build, hire, and develop a high-performing team of 4-5 security engineers with deep expertise across application security, infrastructure security, and corporate security.

- Foster a culture where security judgment accelerates business velocity, creating an environment where specialists thrive through clear expectations, regular coaching, and opportunities for growth.

- Conduct regular one-on-ones and provide constructive feedback that helps your engineers advance their technical depth and expand their cross-functional impact.

- Set team priorities and architectural direction, ensuring your team focuses on the highest-impact security decisions across Lambda's AI infrastructure.

Strategic Architecture & Program Management

- Own your team's 6-12 month roadmap, balancing proactive architecture work (defining security standards and patterns) with reactive consultation (design reviews and complex security questions).

- Establish security policies and architecture standards that enable Product Engineering, Platform Engineering, and IT teams to build secure-by-default systems.

- Define measurable success criteria for your team's work, translating security architecture decisions into business impact that stakeholders understand.

- Proactively guide the evolution of Lambda's security architecture progra
