About the role

Site Reliability Engineer focused on application reliability, primarily coding in TypeScript, with on-site collaboration in Arlington, VA. Hybrid role requiring Secret clearance and relocation if needed, with remote work and on-site customer engagements.

Responsibilities

  • Improving the application: Work directly in the codebase (primarily TypeScript) to fix reliability and performance problems at the source. You'll partner with product engineers on design decisions, review code with reliability and security in mind, and treat "make the app better" as a first-class part of the job rather than something you hand off.
  • Building observability that developers actually use: Design and run our monitoring, logging, and alerting (Prometheus, Loki, Alloy, Grafana). The goal is alerts and dashboards tied to real application behavior, so teams catch issues before users do.
  • Owning reliability targets: Define and measure SLIs and SLOs, wire up alerting that feeds them, and be the person who can say what "reliable" means for our systems and prove it with data.
  • 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 so it doesn’t happen again.
  • Automating away toil: Spot the repetitive operational work and write software to kill it. Share what works with other teams, including those running in air-gapped environments, and help them get production-ready.

Qualifications

  • An 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
