Senior Site Reliability Engineer (Colorado Springs, CO)

📋 Description

• • Own the reliability, scalability, and security of Onebrief’s production applications and platforms across both on-premise DoD environments and AWS/AWS GovCloud cloud infrastructure.
• • Design, implement, and manage a world-class observability platform using Prometheus, Loki, Alloy, and Grafana to create actionable insights and automated alerting that prevent user-impacting issues before they occur.
• • Define, measure, and own Service Level Indicators (SLIs) and Service Level Objectives (SLOs) to establish measurable reliability benchmarks, increasing internal and external trust in system performance.
• • Lead incident response as primary responder or incident commander during critical production outages, directing real-time troubleshooting and conducting blameless post-mortems or After Action Reviews (AARs) to drive systemic, automated fixes.
• • Partner with platform and application teams to design, build, and maintain secure, resilient Kubernetes clusters using Infrastructure-as-Code (Terraform, Ansible), embedding RMF, STIGs, and other DoD compliance controls directly into automation pipelines.
• • Eliminate operational toil by identifying repetitive tasks and automating them through scripting and tooling, improving team efficiency and system stability in air-gapped and high-security environments.
• • Collaborate with Security, Customer Success, and DevOps teams to ensure deployment processes are repeatable, auditable, and aligned with mission-critical operational standards.
• • Serve as the subject matter expert on system reliability, translating failure modes and operational constraints into scalable, automated guardrails that reduce human error and increase system resilience.
• • Develop and maintain comprehensive runbooks, monitoring dashboards, and alerting policies that enable fast recovery and proactive issue detection across distributed, hybrid cloud/on-prem systems.
• • Contribute directly to improving the end-to-end experience of deploying and managing Onebrief in customer environments, particularly in DoD commands across Colorado Springs, CO, where onsite work is required.
• • Mentor team members and foster a culture of blameless learning, continuous improvement, and shared ownership of system reliability across engineering and operational teams.
• • Ensure all infrastructure and operational practices comply with DoD security frameworks including RMF, STIGs, and ICD 503, and maintain strict adherence to secure configuration standards in all environments.
• • Support the readiness of customer and internal teams for production deployments by sharing best practices for managing applications in restricted, air-gapped, and classified network environments.
• • Drive improvements in CI/CD pipeline reliability and security using GitLab CI/CD, Jenkins, or GitHub Actions to ensure rapid, safe, and auditable releases across hybrid environments.
• • Maintain deep familiarity with core networking protocols and secure network configurations to troubleshoot connectivity, latency, and isolation issues in classified and non-classified DoD networks.
• • Act as the primary point of contact for production incidents and operational escalations, ensuring timely communication and resolution while upholding SLA commitments to military customers.
