Senior Site Reliability Engineer (Arlington, VA) - Secret Clearance Required - Relocation Provided

Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination. We're hiring a Site Reliability Engineer to join our Infrastructure & Security team. This is an SRE role for someone who's comfortable in application code. Much of the reliability and performance work happens in the codebase (primarily TypeScript), so you'll fix problems at the source rather than working around them in the infrastructure. You'll be a first line of support for our mission-critical deployments across on-prem DoD and AWS environments, and what you learn in the field will feed directly back into the product.

Responsibilities

Help make production application reliable, scalable, and secure by improving the software itself, not just the systems it runs on; Improving the application: Work directly in the codebase (primarily TypeScript) to fix reliability and performance problems at the source; Building observability that developers actually use: Design and run monitoring, logging, and alerting (Prometheus, Loki, Alloy, Grafana); Owning reliability targets: Define and measure SLIs and SLOs, wire up alerting that feeds them; Leading incident response: Act as incident responder, and incident commander when needed, run blameless post-mortems (AARs) that find the actual root cause and turn it into a code or process fix; Automating away toil: Spot the repetitive operational work and write software to kill it

Requirements

Active Secret clearance; 5+ years in software engineering, SRE, or a related role, with real time spent writing and shipping application code; Strong TypeScript (or comparable modern language experience with willingness to work primarily in TypeScript); Solid grasp of the full SDLC: design, code review, testing, release, and how reliability fits into each stage; Experience with incident response, root cause analysis, and turning findings into lasting fixes; A collaborator who works well across product, platform, and DevOps teams and shares context openly; Application development in TypeScript (Node and/or a modern front-end framework); CI/CD: building and maintaining pipelines (GitHub Actions, GitLab CI/CD, Jenkins); Testing and quality practices as part of the delivery process; Comfort with at least one of Python, Go, or Bash for tooling and automation; Working knowledge of containers and Kubernetes (enough to debug and deploy, not necessarily to stand up clusters from scratch); Networking fundamentals and secure configuration basics; Willingness to relocate to Arlington, VA if not currently within commuting distance

Nice to have

Observability: Grafana stack, ELK, or Datadog; Infrastructure as Code (Terraform, Ansible) and cloud experience (AWS or AWS GovCloud); Kubernetes cluster design and operations; Designing meaningful SLIs/SLOs with error budgets for distributed systems; GitOps practices and toolchains; DoD environments and compliance frameworks (RMF, STIGs, ICD 503); Service mesh (Istio, Linkerd); On-prem virtualization (VMware, Proxmox, Nutanix, Hyper-V); Relevant certs (AWS DevOps Engineer, CKA/CKAD)
