Security Engineer

Chainguard is the trusted source for open source, delivering secure builds for open source software. They are seeking a Security Engineer to support engineers in Identity and Access Management, AI, and Cloud, focusing on operational support and security best practices.

Responsibilities:

• Operate and sustain Chainguard’s technology platforms (cloud, IAM, and AI)
• Help implement and maintain access controls, identity policies, and authentication/authorization systems
• Support the hardening and monitoring of cloud infrastructure alongside senior cloud architects
• Assist in securing AI/ML pipelines and agentic workflows as they scale across the company
• Troubleshoot, automate, and maintain systems using solid IT administration or software engineering skills
• Document processes and contribute to runbooks, playbooks, and internal knowledge-sharing
• Adapt to shifting priorities and pick up new tools or systems as the company's needs evolve
• Learn and apply security best practices under the guidance of senior engineers, with room to specialize over time

Requirements:

• Airtight IT administration skills and/or software development background — this is a must-have foundation for the role
• Hands-on experience in at least one of the following: IAM, AI/ML infrastructure, or cloud platforms (GCP, AWS, or Azure)
• Comfort with scripting, automation, and a troubleshooting mindset
• Outstanding interpersonal skills — you'll be supporting engineers across multiple teams, so clear communication and collaboration matter as much as technical chops
• Comfort with ambiguity and rapid change — this is a fast-moving, late-stage startup environment
• A team-first mentality — someone who's eager to learn, shares context generously, and is motivated by helping teammates succeed
• Security experience or working knowledge is a plus, not a requirement
