Requirements
• We are hiring a Site Reliability Engineer to join our Infrastructure & Security team. You’ll work closely with fellow SREs, security, and customer success. • You will be the first line of support for our mission critical deployments, and responsible for ensuring best-in-class service quality and issue resolution. You will work in both on-premise DoD environments and AWS cloud environments. Your lessons from the field will shape how our team works, from policy to implementation. • In addition to working at the customer, you will contribute directly to solutions that increase stability, performance, and security of our deployments, and improve the overall experience of deploying and managing Onebrief on premise. • You care deeply about reliability and treat it as a core feature of any application or platform, with a bias toward “reliability over novelty.” You think about infrastructure and operability as products to be automated, well-documented, and continuously improved, and you aim to leave systems easier to operate than you found them. • You are equally comfortable leading a post-incident review, or diving into a kubectl shell to triage a complex production issue. You don't just fix problems; you translate constraints and failure modes into clear, automated guardrails and scalable, resilient architecture. For you, robust monitoring, actionable alerting, and insightful runbooks are core parts of the engineering process, not afterthoughts. • You mentor others, fostering a culture of blameless postmortems and proactive reliability. You collaborate naturally with application and platform teams, helping them move quickly but safely by building the tools, processes, and observability that make "fast recovery" a reality. • Experience in DoD environments and compliance frameworks (RMF, STIGs, ICD 503). • GitOps practices and toolchains. • Security‑minded design for sensitive environments. • Experience designing and implementing meaningful SLIs/SLOs (including error budgets) for complex, distributed systems. • Familiarity with on‑prem virtualization(VMware, Proxmox, Nutanix, Hyper-V, etc). • Service mesh exposure (Istio, Linkerd). • Relevant certifications (e.g., AWS DevOps Engineer, CKA/CKAD). • Active Security+ or another DoD 8570.01-approved security credential, or the ability to obtain the valid credentials within 3 months of employment. • Notice to Third Party Recruitment AgenciesPlease note that Onebrief does not accept unsolicited resumes from recruiters or employment agencies.

You will embed security and compliance controls (RMF, STIGs) directly into this automation. • Automating for Scale and Security: • Eliminating Toil and Scaling the Team: Proactively identify and eliminate operational toil by building automation. You will partner with other teams to share best practices for air-gapped environments and support their readiness for production. • Eliminating Toil and Scaling the Team: • What We Look For • What We Look For • An active Top Secret clearance • 5+ years in Platform, DevOps, or Site Reliability Engineering with an infrastructure and operations focus. • Proven partner to DevOps/Platform and application teams; collaborates well across functions and shares context openly. • A deep understanding of incident response processes, with experience conducting thorough root cause analyses and driving continuous improvement. • Technical expertise • Technical expertise • Infrastructure as Code: Terraform (or CloudFormation), Ansible. • Containers and orchestration: Kubernetes design, deployment, and operations. • CI/CD: experience building and maintaining pipelines (GitLab CI/CD, Jenkins, GitHub Actions). • Scripting: proficiency with at least one of Python, Go, or Bash. • Cloud: Familiarity with AWS or AWS GovCloud. • Observability: Grafana stack, ELK stack, or Datadog. • Networking fundamentals: core protocols and secure configurations.
