• If you thrive on solving complex security challenges in cutting-edge AI infrastructure and want to build security programs that scale from hundreds to thousands of systems, we'd love to talk
• Have 5+ years of hands-on security engineering experience and 10+ years of total engineering experience, with demonstrated impact protecting enterprise infrastructure
• Thrive in high-speed, high-ambiguity startup environments where you build security programs while responding to immediate threats
• Deep technical expertise with security tooling including SIEM/SOAR platforms, EDR solutions, vulnerability scanners, and cloud security monitoring
• Excel at solving complex problems in Python, Go, or similar languages, building automations that scale security impact
• Proven ability to work effectively with cross-functional technical teams both with and without authority (we're all on the same team!)
• Strong Linux systems experience in both bare metal and cloud environments, understanding infrastructure from kernel to application layer
• Demonstrated experience driving security improvements that were enthusiastically adopted by engineering teams
• Excellence at translating security concerns into business risk, enabling stakeholders to make informed decisions

Desirable

• Engineering at Lambda is responsible for building and scaling our cloud offering. Our scope includes the Lambda website, cloud APIs and systems as well as internal tooling for system deployment, management and maintenance
• 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
• As a Staff Security Engineer, you'll be the technical backbone of our security program, building and implementing security solutions that directly protect customer data and enable Lambda to be the safest place to build with AI
• Reporting to the Senior Manager of Security and collaborating closely with Product Engineering, Platform Engineering, and embedded Technical Program Managers, you'll drive hands-on security improvements across our AI-focused infrastructure. Your work will span detection and response systems, vulnerability management, security architecture, and tooling that scales with our rapid growth while maintaining the highest security standards
• You will work on implementing enterprise-grade detection capabilities, automating incident response workflows, hardening our multi-cloud and bare metal infrastructure, and establishing security tooling that positions Lambda as the industry's most trusted AI computing platform. You'll have unique access to LLMs hosted on our own infrastructure to pioneer AI-powered security solutions that wouldn't be possible anywhere else
• Drive Security Improvements: Design and implement comprehensive security solutions including detection capabilities, automation, and endpoint detection and response (EDR) across Lambda's infrastructure
• Lead Incident Response: Drive critical security incident resolution, developing response automation and conducting post-incident reviews that strengthen our security posture
• Develop Security Architecture: Create security architecture patterns and implementation guides that engineering teams can adopt to build secure-by-default systems
• Build Detection & Response: Implement and tune SIEM/SOAR solutions, creating detection rules that identify threats while minimizing false positives
• Pioneer AI-Powered Security: Leverage Lambda's hosted LLMs to build next-generation security capabilities including automated threat analysis, intelligent alert correlation, and AI-assisted incident response that push far beyond traditional approaches
• Collaborate Across Engineering: Partner with Product and Platform Engineering teams to integrate security requirements into their development cycles at optimal moments
• Mentor Security Excellence: Coach engineers across the organization on secure coding practices and security tool usage, multiplying your impact
• Drive Vulnerability Management: Establish and operate vulnerability scanning, prioritization, and remediation programs that protect critical assets
• Develop Security Tooling: Build security tools and automations that enable teams to maintain security standards without sacrificing development velocity
• Advocate for Security: Communicate security value to stakeholders, translating technical risks into business impact for informed decision-making

• If you do not meet all of these requirements but believe you may be a good fit, please still apply and provide a cover letter that helps us understand your readiness for a staff security engineering role
