Job Details

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

We are looking for a Security Engineer to join our team. As a Security Engineer on our Architecture team, you'll be the technical foundation of our security design decisions, creating security architecture patterns and standards that directly protect customer data and enable Lambda to be the safest place to build with AI.

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.

What You'll Do

• Drive Security Architecture: Design and document comprehensive security patterns, standards, and implementation guides that engineering teams can adopt to build secure-by-default systems.
• Lead Security Reviews: Conduct security design reviews and develop threat models for critical systems, identifying risks and providing actionable recommendations.
• Develop Security Requirements: Create clear security requirements and acceptance criteria that integrate seamlessly into engineering development cycles.
• Build Security Solutions: Prototype and implement security controls, tools, and automation that demonstrate secure patterns and enable self-service security.
• Pioneer AI-Powered Architecture: Leverage Lambda's hosted LLMs to build next-generation security capabilities including automated threat modeling, AI-assisted security reviews, and intelligent architecture recommendations that push far beyond traditional approaches.
• Collaborate Across Engineering: Partner with Product and Platform Engineering teams to integrate security architecture requirements into their designs at optimal moments.
• Enable Customer Trust: Develop customer-facing security documentation, architecture whitepapers, and technical security content that demonstrates our security maturity.
• Mentor Security Excellence: Coach engineers across the organization on secure design principles and security architecture patterns, multiplying your impact.
• Drive Architectural Standards: Establish and maintain security architecture standards that protect critical assets while enabling development velocity.
• Advocate for Security: Communicate security architecture value to stakeholders, translating technical risks into business impact for informed decision-making.

What We Think a Candidate Needs to Demonstrate to Succeed

• Have 3+ years of security engineering or security architecture experience and 5+ years of total engineering experience, with demonstrated impact protecting enterprise infrastructure.
• Thrive in high-speed, high-ambiguity startup environments where you are constantly balancing security goals with business needs.
• Deep technical expertise in security architecture patterns, threat modeling methodologies, and security design principles.
• Excel at solving problems through design and prototyping in Python, Go, or similar languages.
• Proven ability to work effectively with cross-functional technical teams both with and without authority.
• 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 architecture decisions into business risk, enabling stakeholders to make informed decisions.

Nice to Have

• You've led the security assessment and requirements for major platform components or enterprise systems.
• Experience driving or providing significant evidence for compliance audits, such as SOC 2, ISO 27001, PCI-DSS, HIPAA/HITECH, or FedRAMP.
• Deep experience with cloud security architecture and cloud provider security services (AWS, GCP, Azure).
• Experience with AI/ML system security, including model security, data pipeline protection, or adversarial threat modeling.
• You've developed security architecture patterns that were adopted across multiple engineering teams.
• Security certifications like CISSP, OSCP, or similar that demonstrate continued learning.
• Experience with infrastructure-as-code security patterns and secure DevOps practices.
• Excitement about leveraging our direct access to state-of-the-art LLMs to revolutionize security architecture.
