5+ years of experience in Platform Engineering, DevOps, or Site Reliability Engineering
Proven experience leading organization-wide infrastructure initiatives and executing roadmaps aligned with business objectives
Deep experience operating in highly regulated, secure, and/or air-gapped environments, including the Department of War or the Intelligence Community
Expert-level knowledge of Kubernetes, including multi-cluster design, security, and the broader CNCF ecosystem
Experience designing enterprise-grade infrastructure-as-code and automation frameworks using tools such as Terraform or Ansible
Proficiency in Python and Bash for building custom tooling and automation
Ability to communicate complex technical strategies to engineers and stakeholders and build alignment around long-term architectural decisions
