• Implement infrastructure as code using Terraform and Ansible and standardize industry best practices.
• Mentor engineers, lead technical design and code reviews, and provide constructive feedback.
• Resolve complex production incidents, conduct root-cause analyses, and participate in on-call rotations.

Requirements

• 8+ years of experience in infrastructure engineering, site reliability engineering, or a related systems-focused field.
• 8+ years of experience architecting, scaling, and managing enterprise-grade observability stacks using Prometheus, Grafana, Thanos, Mimir or Cortex, and OpenTelemetry.
• Experience designing cloud-native infrastructure on AWS or GCP.
• Experience managing production Kubernetes environments, including EKS and GKE.
• Advanced proficiency with Terraform and Ansible for managing immutable infrastructure.
• Experience maintaining and optimizing high-throughput, large-scale distributed systems, with a focus on cost efficiency, scalability, and disaster recovery.
• Ability to lead complex technical designs, mentor engineers, and collaborate with product and application teams.
• U.S. citizenship and the ability to work in a government-regulated environment.

Preferred Qualifications

• 8+ years of production-level programming experience in Go or another mainstream language such as Python or Java, with a willingness to adopt Go.
• Experience with FedRAMP or other sovereign cloud compliance requirements.
• Familiarity with on-premises, hybrid, or air-gapped Kubernetes deployments.
