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:

As the Senior Site Reliability Engineer (SRE) for Network & Transport Systems, you will serve as a foundational technical pioneer establishing modern SRE culture, practices, and tooling across the operations organization. In this role, your primary mission is to engineer the reliability of physical, virtual, and hybrid transport infrastructure—treating network routing, switches, firewalls, and data center transit as software‑defined, automated systems.

You will eliminate manual operational toil by authoring robust automation code (Python, Go, Ansible, Terraform), architecting end‑to‑end telemetry and monitoring pipelines, and defining critical Service Level Indicators and Objectives (SLIs/SLOs) for network uptime, latency, and packet health. In close collaboration with cloud and platform engineering teams, you will ensure seamless, secure transit handoffs into hybrid‑cloud environments, lead blameless incident post‑mortems, and drive systemic resilience across all enterprise transport services.

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 Transport Networks: Introduce SRE culture to J6 operations, focusing specifically on automating network, transit, and hardware‑level infrastructure.
• Engineer Network Automation (NetDevOps): Write code (Python, Go, Ansible) to automate router/switch configurations, load balancing, and firewall rules, eliminating manual CLI configurations.
• Architect Infrastructure Observability: Deploy advanced telemetry pipelines (SNMP, gRPC, syslog) to monitor physical and virtual transport networks, alerting on latency and routing anomalies.
• Establish Network SLOs & SLIs: Define and measure Service Level Indicators/Objectives specifically for packet loss, jitter, network latency, and circuit uptime.
• Bridge to Cloud & Domain Environments (15%): Partner closely with the Cloud SRE to design and optimize seamless, secure transit handoffs between physical transport networks and hybrid‑cloud environments.
• Drive Automated Incident Response: Lead incident response for core transport outages, focusing on building software‑driven auto‑remediation (e.g., automated traffic rerouting during a link failure).

Key Skills

• Network Automation
• Site Reliability Engineering
• Infrastructure as Code
• Network Protocols
• Network Security
