About the role

  • Design, build, and maintain advanced telemetry and automation tooling to monitor global platform health and trigger automated corrective actions.
  • Own and improve incident response runbooks and automated remediation workflows, reducing MTTR over time.
  • Participate in on-call rotations, diagnosing and resolving system issues and escalations from the customer support team (this is an internal-facing role, not customer-facing).
  • Drive continuous improvement through post-incident reviews (PIRs) and engineering initiatives that eliminate classes of failure.
  • Develop advanced monitoring software in python and GoLang.
  • Contribute to full-stack troubleshooting across our React.js frontend, Python backend services (Flask, Litestar, Celery), and AWS-managed Kafka (MSK/ESK).
  • Write infrastructure-as-code using Terraform, building reusable modules and submodules to provision and manage cloud resources.
  • Focus on coding advanced telemetry, implementing automation strategies, and building tools that proactively monitor platform health.
  • Rotate into an operational role to swiftly diagnose system issues and handle internal escalations, ensuring continuous platform stability.
  • Use insights gained during the operations week to develop automated solutions that reduce future incidents and optimize system performance.
