Senior Security Engineer (Infrastructure)

Chainguard is the trusted source for open source, delivering hardened, secure, and production-ready builds of software used by engineers and AI agents. The Senior Security Engineer will engineer and secure the company's multi-cloud infrastructure, embed security into engineering architecture and tooling, and support cloud resilience, automation, disaster recovery, AI-driven pipelines, and incident response.

Responsibilities:

• 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

Requirements:

• Outstanding interpersonal and communication skills
• Strong, hands-on GCP or AWS engineering experience required
• 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
• Experience with Azure also a plus
• Comfort with ambiguity and rapid change: prior experience at a fast-moving or late-stage startup is a strong plus
