Job summary

Gallatin is seeking a Site Reliability Engineer to keep production systems running with reliability for national security missions. You will work at the intersection of infrastructure, automation, and mission-critical uptime, building and operating systems that turn logistics data into decisions in real time, including in classified environments.

This hands-on role requires treating reliability as a product, instrumenting before outages, automating toil away, and owning incidents from detection

Qualifications

• Active Secret clearance required; willingness to obtain a higher-level clearance if needed.
• 3–5 years of experience in a site reliability engineering, DevOps, or production infrastructure role.
• Strong technical background in Linux systems, networking, and cloud infrastructure (AWS, Azure, or GovCloud equivalents).
• Hands‑on experience with infrastructure-as-code (Terraform, Ansible, or similar) and container orchestration (Kubernetes, Docker).
• Experience building and maintaining CI/CD pipelines and automated deployment systems.
• Familiarity with monitoring and observability tooling (Prometheus, Grafana, Datadog, ELK, or similar).
• Track record of owning production incidents end-to-end, from detection through resolution and postmortem.
• Comfort operating in classified, air‑gapped, or otherwise network‑constrained environments.
• Clear written and verbal communicator who can work directly with both engineers and government stakeholders.
• Willing to travel >50% of the time to customer and government sites.

Responsibilities

• Own the reliability, availability, and performance of production systems supporting Gallatin's logistics decision platform, including services deployed in classified and air-gapped environments.
• Build and maintain monitoring, alerting, and observability pipelines that surface problems before customers do.
• Lead incident response for production issues, driving triage and resolution and running blameless postmortems that turn into concrete engineering fixes.
• Design and operate CI/CD pipelines and infrastructure-as-code that let engineering ship safely and often, across both cloud and classified network environments.
• Automate manual operational work (deployments, scaling, failover, credential rotation) to reduce toil and remove single points of failure.
• Harden systems to meet DoD security and compliance requirements (e.g., RMF, STIGs, ATO processes) without slowing down delivery.
• Partner with software engineers to define SLOs/SLIs and build reliability into services from design through deployment.
• Work directly with government customers and field teams to understand mission environments and translate operational constraints into system requirements.
• Document runbooks, architecture decisions, and operational procedures so the systems you build can be run by the whole team, not just you.
