• Help design secure defaults for new services, workers, queues, databases, internal tools, and deployment pipelines
• Improve detection and response for suspicious access, leaked credentials, abnormal sending behavior, privilege changes, and sensitive system events

You will be a great fit if you...

• Have experience securing production infrastructure, cloud environments, APIs, developer platforms, or multi-tenant SaaS products
• Can write code and are comfortable reading application, infrastructure, and deployment code
• Understand authentication, authorization, secrets, IAM, logging, audit trails, incident response, and secure deployment pipelines.

You will be an exceptional fit if you also...

• Have secured cloud infrastructure using tools like AWS, Terraform, Kubernetes, Cloudflare, or similar systems
• Have experience with open source security, GitHub organization hardening, package publishing, dependency review, or supply-chain security
