We’re seeking a Senior Site Reliability Engineer – Observability with deep expertise in designing, building, and operating observability solutions across application, database, host, and container environments. In this role, you will lead the development of a modern, open-source observability platform – leveraging technologies such as Grafana, Prometheus, or similar – that is scalable, resilient, and cost-effective. This platform will form the foundation for enterprise-wide monitoring and log management, empowering teams to gain actionable insights, optimize performance, and improve system reliability.

This is a high-impact role for a self-starter who takes initiative and drives outcomes, with ownership spanning observability platforms, governance, agent fleet management, automation, and Fin Ops practices – shaping how Moderna advances its observability strategy in a rapidly growing global enterprise.

Your Key Responsibilities Will Be

• Manage and advance Moderna’s enterprise observability platform with a focus on open-source and SaaS observability technologies (Grafana, Prometheus, Loki, Tempo, Jaeger, Open Telemetry, Dynatrace, Splunk, etc.).

• Lead governance, agent fleet management, and Fin Ops optimization to ensure the platform is scalable, cost-effective, and compliant with enterprise requirements.

• Balance hands-on engineering work (building, configuring, and operating the platform) with strategic ownership (roadmap influence, governance, cost optimization).

• Collaborate with vendors and open-source communities to influence feature roadmaps and maximize platform value.

• Design and build highly scalable, resilient, and cost-optimized observability architectures to support application, database, host, and container monitoring.

• Implement telemetry pipelines for metrics, traces, and logs using Grafana, Prometheus exporters (e.g., Node, Blackbox), Kubernetes instrumentation, distributed tracing, or similar technologies.

• Establish and evolve best practices for monitoring, alerting, SLOs/SLIs, and incident detection across hybrid environments (cloud-native and on-prem).

• Partner with application and infrastructure teams to enable self-service observability capabilities, accelerating troubleshooting and reliability improvements.

• Build and maintain enterprise-scale log management capabilities within the observability platform.

• Evolve log management to serve as a scalable, cost-effective alternative to traditional log aggregation solutions.

• Partner with security and infrastructure teams to ensure logging meets performance, compliance, and retention requirements.

• Integrate observability solutions with incident management platforms such as Pager Duty to streamline escalation, response, and workflow automation.

• Oversee and optimize on-call processes, ensuring alerts are actionable, routed effectively, and resolved quickly.

• Provide real-time telemetry during incidents and support root cause analysis (RCA) backed by observability data.

• Develop automation using Python, Terraform,…
