Job description

Join the Defense Information Systems Agency (DISA), where we deliver the secure IT and communications capabilities that keep our Nation’s Warfighters and senior leaders connected anytime, anywhere. Within Command, Control, Communications and Computers (C4) Enterprise Directorate (J-6), we empower our Nation’s senior leaders and the warfighter community with assured enterprise services to win in an evolving global landscape.

Position Overview: The Senior Site Reliability Engineer (Cloud & Domain Services) leads reliability engineering for core cloud platforms and enterprise domain services, applying automation, observability, and performance engineering to ensure highly available, self‑healing systems. The role builds cloud‑native IaC automation, streamlines identity and directory operations, and enhances the reliability of virtual desktop environments through scalable, automated mechanisms. The Senior SRE defines and measures service reliability across authentication, platform availability, and domain operations, architects deep observability frameworks, and partners with transport SRE counterparts to maintain secure, performant connectivity between cloud services and underlying network infrastructure.

Salary: $143,913 to $187,093 per year(inclusive of TLMS and locality adjustments)

Location: Fort Meade, MD; Arlington, VA

Major Duties:

• Pioneer SRE for Cloud & Core Domains: Lead the cultural SRE transformation within the J6 operations organization, focusing specifically on automating the reliability of cloud platforms, virtual desktops, and directory services.
• Engineer Cloud Platform Automation: Write clean, modular infrastructure-as-code (IaC) templates (e.g., Terraform) to automate the deployment, scaling, and configuration of Azure services and Kubernetes (AKS) clusters.
• Automate Core Directory & Identity Services: Author scripts (PowerShell, Python) to automate Active Directory (AD/Entra ID) administration, group policy enforcement, and identity synchronization, removing manual "toil."
• Optimize Virtual Desktop Reliability: Engineer automated scaling, performance monitoring, and rapid recovery mechanisms for Azure Virtual Desktop (AVD) environments to ensure a seamless end-user experience.
• Define Application & Domain SLOs: Collaborate with stakeholders to define and monitor Service Level Indicators (SLIs) and Service Level Objectives (SLOs) specifically for cloud service availability, authentication latency, and system uptime.
• Architect Cloud-Native Observability: Design and deploy comprehensive monitoring, logging, and tracing frameworks (e.g., Azure Monitor, Prometheus/Grafana) to gain deep visibility into platform health and application performance.
• Partner with Transport SRE (15%): Collaborate closely with your Transport/Infrastructure counterpart to ensure highly reliable, performant, and secure connectivity between your core cloud platform and the underlying transport networks.
