The role in a nutshell:

We're looking for a Sr 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 isn't just internal plumbing: it's the platform our product runs on, so 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 - and this role sits right at that intersection. You'll report to the Director of Cyber Resiliency and partner closely with our Developer Platform and IAM teams to make sure every cloud environment we operate - primarily GCP, with AWS and Azure in the mix - is resilient, well-architected, and built to accelerate secure innovation rather than slow it down. Let us know if bonfires are your jam! We're a late-stage startup, which means priorities, tooling, and scope can shift quickly - you'll need to be energized by that pace rather than worn down by it. Like every Chainguardian, you'll take the work seriously without taking yourself too seriously, and default to good intentions in how you work with others.

What you'll do:

• Architect and maintain cloud environments built to be secure, resilient, and optimized for performance
• Partner hands-on with the Developer Platform team to embed security into the architecture and tooling developers use every day
• Work closely with our IAM counterparts to design and enforce identity and access strategies across all cloud environments
• Harden cloud platforms against emerging threats while keeping them resilient and highly available
• Bring a DevOps mindset - 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 across engineering, translating security requirements into practical, adoptable designs that other teams actually want to use - sharing context generously and putting shared outcomes ahead of individual credit
• Help set the long-term architectural vision for how our cloud environments scale securely
• 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:

• Strong, hands-on GCP administrative experience - this is a must-have, not a nice-to-have
• Experience with AWS and/or Azure is a plus
• Solid DevOps background - comfort with Terraform/IaC, Kubernetes (GKE), and CI/CD pipelines
• Familiarity with software supply chain security concepts particularly SLSA is a strong plus
• Experience securing or architecting AI/ML infrastructure or agentic workflows
• Outstanding interpersonal and communication skills - you'll plan, coordinate, and build consensus with the Developer Platform team, IAM stakeholders, and other partners across the org
• Staff-level experience architecting and securing complex, multi-cloud environments
• Comfort with ambiguity and rapid change - prior experience at a fast-moving or late-stage startup is a strong plus
• A track record of designing systems that are secure, resilient, and built to accelerate - not slow down - engineering velocity
