A3 Technology, Inc. is seeking a senior level Windows Server Dev Ops Engineer to join our team in Washington, DC.

• Own Windows Server production operations (day one). Serve as the senior technical owner for a predominantly Windows Server environment (~95% Windows), providing hands‑on production support for mission‑critical applications hosted in government cloud (AWS Gov Cloud).
• Administer and sustain Windows Server. Maintain, troubleshoot, patch, harden, and recover Windows Server systems in production—sustaining availability during business hours and through a shared on‑call rotation, independently resolving after‑hours incidents.
• Take ownership of Kubernetes. Independently operate and troubleshoot the Kubernetes environment (EKS), resolving complex cluster, workload, and platform issues and supporting existing production applications and workloads.
• Lead incident response. Drive production incident response and deep‑dive root‑cause analysis across Windows Server, cloud, and container platforms.
• Engineer secure cloud infrastructure. Design, implement, and maintain secure, scalable cloud architectures across Windows and Linux systems; work independently or lead small teams.
• Automate with IaC (secondary). Develop and manage Infrastructure as Code using Terraform and Ansible to provision and configure environments—secondary to Windows operations and Kubernetes troubleshooting.
• Build CI/CD and Dev Sec Ops . Develop and maintain CI/CD pipelines and Dev Sec Ops  automation aligned with government and industry best practices.
• Monitor and ensure availability. Design and implement monitoring, logging, and alerting solutions; establish performance baselines and ensure system availability.
