Senior Security Engineer (Infrastructure)
The role in a nutshell:
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.
What you'll do:
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 DevOps 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
What we're looking for:
Outstanding interpersonal and communication skills
Strong, hands-on GCP or AWS engineering experience required
Experience with Azure also a plus
Solid DevOps background: comfortable using Terraform/IaC, Kubernetes (GKE), and CI/CD pipelines
A track record of designing systems that are secure, resilient, and built to accelerate engineering velocity
Comfort with ambiguity and rapid change: prior experience at a fast-moving or late-stage startup is a strong plus
