Senior Security Engineer; Infrastructure

• We’re looking for a Senior Security Engineer to engineer and secure our multi-cloud environment, the same cloud infrastructure that powers our product
• This is a cloud-native, AI-obsessed company, and our cloud is the platform our product runs on
• How we design, harden, and evolve it directly shapes what we can build and how fast we can build it safely
• As open source software increasingly feeds AI agents as well as human engineers, securing that supply chain end-to-end is core to our mission
• You’ll formally report to the Sr Director of Cyber Resiliency and spend time embedded in project pods building alongside our product engineering partners
• We’re a late-stage startup, which means priorities, tooling, and scope can shift quickly
• Engineer and maintain cloud environments built to be secure, resilient, and optimized for performance
• Partner hands-on with internal engineering teams to embed security into the architecture and tooling developers use every day
• Work closely with our IAM counterparts to design and enforce secure identity and access strategies across all cloud environments
• Harden cloud platforms against emerging threats while keeping them resilient and highly available
• Lead cloud-centric disaster recovery exercises
• Bring a Dev Ops mindset by building automation, pipelines, and guardrails using Terraform/IaC and Kubernetes
• Help secure the infrastructure behind AI-driven pipelines and agentic workflows as they become a growing consumer of the software supply chain
• Act as a trusted advisor and collaborator to product engineering translating requirements into secure practical infrastructure that other teams will rapidly adopt
• Adapt architecture and priorities as the company scales, reworking plans as needs, tooling, or team structure shift
• Assist during relevant incident response investigations

• Equity/stock options
• Unlimited PTO
• Remote work with flexible coworking and team meetup opportunities
• Home office and internet stipend
• 100% health/dental/vision insurance coverage for you and your family
