Zoox is looking for an AWS Cloud Security Engineer to lead the design and implementation of secure, scalable, and software-defined infrastructure in our AWS cloud environment. This role is responsible for establishing best-in-class security practices across AWS, driving automation-first infrastructure security, and partnering with engineering and platform teams to embed security into every layer of our technology stack.   You’ll act as a security champion, ensuring that infrastructure designs meet the highest standards of confidentiality, integrity, and availability — while maintaining operational efficiency and scalability through Infrastructure as Code (IaC). In this role, you will: • Define and own the multi-year security architecture and roadmap for Zoox's robots and fleet, spanning embedded/firmware, in-vehicle networks, cloud, and supporting infrastructure. • Partner with hardware, firmware, autonomy, and infrastructure engineering teams to embed security requirements into system design from the ground up, rather than bolting them on after the fact. • Lead threat modeling and architecture reviews for new vehicle platforms and major feature launches, identifying and prioritizing systemic risk across the fleet. • Set technical standards and guardrails - secure boot, key management, network segmentation, update/OTA security, and more - and drive their adoption across engineering teams. • Represent Product Security in cross-functional and leadership discussions, translating technical risk into business and safety impact for the organization. Qualifications • 10+ years of experience in security engineering, including significant time in an architect, staff, or technical lead capacity. • Deep expertise in embedded/IoT security, including secure boot, TPM/TEE, cryptographic key management, and hardened firmware/OS design. • Demonstrated experience architecting security for complex, physical/cyber-physical systems (automotive, robotics, aerospace, industrial control, or similar). • Strong track record of driving cross-functional technical strategy and influencing engineering leadership without direct authority. • Solid understanding of network security, cloud security, and secure software development lifecycle practices. Bonus Qualifications • Experience securing autonomous vehicles, robotics platforms, or other safety-critical connected systems at scale. • Background in offensive security (red teaming, penetration testing) that informs strong architectural/defensive judgment. • Contributions to industry standards, published research, or conference talks in embedded/IoT/automotive security.
