• Expertise in monitoring/observability platforms (Datadog, Prometheus, Grafana, New Relic).
• Knowledge of web app infrastructure, networking, load balancing, and security best practices.
• Excellent communication and incident leadership.

Responsibilities

• Define, implement, and own SLOs/SLIs across critical platform services.
• Build and maintain monitoring, alerting, and observability systems (Datadog, Prometheus, Grafana).
• Establish error budgets and balance feature velocity with reliability.
• Lead incident response, postmortems, and systemic improvements to prevent recurrence.
• Design chaos engineering practices to identify failure modes proactively.
• Architect and optimize Kubernetes‑based platform for reliability and cost efficiency.
• Support large infrastructure migrations with minimal business disruption.
• Contribute to platform migration evaluations and risk mitigation.
• Build automated deployment pipelines with feature flags and rollback capabilities.
