• Strong knowledge of AWS infrastructure, including VPC, EKS, Terraform, Docker, and Kubernetes.
• Advanced understanding of Linux systems and web application security.
• Experience troubleshooting and resolving complex infrastructure issues.
• Ability to navigate technical ambiguity and execute large, cross-team projects with minimal guidance.
• Leadership experience in mentoring junior engineers and driving process improvements across teams.
• Excellent communication skills with the ability to collaborate with product and engineering stakeholders.
• Familiarity with modern container systems and technologies such as Redis, Vault, Terraform, PostgreSQL, AWS, CloudFlare, and CI/CD tools like CircleCI, GitHub Actions, ArgoCD, and MongoDB.

Nice to Have:

• Experience building and operating highly secure systems, focusing on SOC2 & PCI compliance, observability, and automation.
• Experience scaling technical infrastructures and defending corporations against DDoS, malware, and other exploits.
• Strong coding/scripting experience in Typescript, Golang, Bash, HCL, and Python.
