🏢 About Chainguard

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.

🎯 The Role

As a Senior Security Engineer at Chainguard, you will be responsible for engineering and securing our multi-cloud environment. You will work closely with internal engineering teams to embed security into the architecture and tooling developers use every day. Your role will involve hardening cloud platforms against emerging threats while keeping them resilient and highly available. You will also lead cloud-centric disaster recovery exercises and bring a DevOps mindset by building automation, pipelines, and guardrails using Terraform/IaC and Kubernetes.

✅ Key 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

📌 Required Qualifications

• 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

⭐ Desirable Experience

Experience with Azure is a plus.

🎁 Benefits

• Flexible & Remote-First Culture: Work remotely with team meetup opportunities, bi-annual destination summits, and a monthly stipend for coworking spaces, phone and internet costs.
• Our Approach to Equity: Receive stock options upon hire and promotion. Plus, you can participate in secondary offerings and have 10 years to exercise your options.
• 100% Covered Health Insurance: We cover 100% of your health, vision and dental insurance premiums for you and your dependents. Nothing comes out of your paycheck.
• ∞ Flexible Time Off: Take the time you need – to do our best work, we need to recharge and reset.
