• Experience designing cloud-native infrastructure in major cloud providers (AWS or GCP) and managing production Kubernetes environments (EKS, GKE).
• Advanced proficiency with IaC and automation tools, specifically Terraform and Ansible.
• Experience maintaining and optimizing high-throughput, large-scale distributed systems with focus on cost-efficiency, scalability, and disaster recovery.
• Demonstrated ability to lead complex technical designs, mentor engineers, and collaborate cross-functionally.
• US Citizenship and ability to work in a government-regulated environment.
