  • Deploy monitoring and log aggregation tools to improve observability
  • Collaborate with teams to identify bottlenecks and deploy scalable, automated solutions

What We're Looking For:

  • 6+ years of Linux system administration and engineering experience in performance-critical environments
  • Proficiency in Python and bash Scripting, with hands-on Ansible experience
  • Solid networking fundamentals: IP Addressing, VLANs, etc.
  • Familiarity with observability tools like Prometheus, Grafana, and ELK
  • Infrastructure-as-code experience with Terraform and CI/CD pipelines
  • Proven ability to resolve complex system-level issues and performance challenges
  • Knowledge of container orchestration tools (Docker/containers, Kubernetes)
