Onebrief builds AI-powered collaboration and workflow software for military planning and operational coordination. This role is part of the Infrastructure & Security team, serving as a first-line responder for mission-critical deployments across on-premise DoD environments and AWS cloud infrastructure.
You will own reliability, scalability, and security of production systems by implementing world-class observability platforms (Prometheus, Loki, Alloy, Grafana), defining and measuring Service Level Indicators and Objectives, and leading incident response and post-mortems. You'll design and manage secure, resilient Kubernetes clusters and cloud/on-prem environments using Infrastructure-as-Code (Terraform, Ansible), embedding security and compliance controls (RMF, STIGs) directly into automation.
Key responsibilities include: designing monitoring and alerting stacks that provide actionable insights; defining reliability standards and measuring them; acting as incident commander during critical incidents; partnering with platform engineers on secure infrastructure design; and proactively eliminating operational toil through automation.
Required qualifications: Active Top Secret clearance (SCI eligibility a plus); 5+ years in Platform, DevOps, or Site Reliability Engineering with infrastructure and operations focus; deep understanding of incident response and root cause analysis; expertise in Terraform/CloudFormation, Ansible, Kubernetes, CI/CD pipelines (GitLab CI/CD, Jenkins, GitHub Actions), Python/Go/Bash scripting, AWS/AWS GovCloud, and observability tools (Grafana, ELK, Datadog); networking fundamentals.
Bonus experience includes DoD environments, compliance frameworks (RMF, STIGs, ICD 503), and GitOps practices. The role requires regularly working on-site at customer locations in Colorado Springs; relocation assistance provided if needed. You'll mentor others and foster a culture of blameless postmortems while collaborating across application and platform teams.
