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.

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.

Securing the Corporate Environment

• Make the safe way to use AI tools and agents the easy way, with approved tools, connectors, and agent environments.
• Ensure humans, agents, and integrations move sensitive data only along reviewed paths, following Lambda's data protection strategy.
• Build automation to verify access in every app changes when someone's job changes and ends when they leave.
• Determine what a person, device, contractor, or agent must prove before reaching company systems, then engineer the checks and access paths that enforce it.
• Keep every corporate device hardened, monitored, and patched, building on the MDM and EDR platforms IT runs.
• Continuously find unmanaged SaaS, risky configuration, and sensitive data shared beyond where it belongs, and drive each finding to a fix.
• Turn contested trade-offs into clear rules with a defined path for exceptions.

Working Across Lambda Security

• Ship Python or Go automation on top of the platforms IT runs, using Lambda-hosted LLMs, frontier models, and AI tools.
• Measure control coverage and effectiveness, and partner with GRC so audit evidence comes straight from the controls.
• Make corporate systems produce the telemetry D&R needs, and help respond to incidents in your area.
• Help IT and engineering partners build secure instincts, and mentor newer members of the security team.

Requirements

• 5+ years of demonstrated security engineering in enterprise or corporate security.
• A track record of independently owning security work end to end.
• Experience in high-speed, high-ambiguity startup environments.
• Hands-on depth in workforce identity, including identity providers and SSO, federation and provisioning standards, MFA, and privileged access.
• Practical experience securing corporate SaaS, managed endpoints, and network access built on zero-trust principles.
• Ability to ship high-quality automation in Python, Go, or similar.

Nice to Have

• Experience securing contractor or personal-device access without managing the device.
• Experience controlling where data flows in AI-heavy or SaaS-heavy environments.
• Experience isolating developer or agent workloads.
• Experience managing identity, SaaS, or endpoint configuration as code.
• Experience supporting SOC 2, ISO 27001, or FedRAMP audits with evidence from corporate controls.

Benefits

• Generous cash & equity compensation.
• Health, dental, and vision coverage for you and your dependents.
• Wellness and commuter stipends for select roles.
• 401k Plan with 2% company match (USA employees).
• Flexible paid time off plan.
