Senior Site Reliability Engineer - Observability

Join to apply for the Senior Site Reliability Engineer - Observability role at Moderna

We are 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 (e.g., 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 FinOps practices – shaping how Moderna advances its observability strategy in a rapidly growing global enterprise.

Here’s What You’ll Do

Your Key Responsibilities Will Be

• Platform Ownership & Operations : Manage and advance Moderna’s enterprise observability platform with a focus on open-source and SaaS observability technologies (Grafana, Prometheus, Loki, Tempo, Jaeger, OpenTelemetry, Dynatrace, Splunk, etc.).
• Lead governance, agent fleet management, and FinOps 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.
• Observability Engineering : Design and build 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, 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.
• Log Management : 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.
• Incident Response & Collaboration : Integrate observability solutions with incident management platforms such as PagerDuty 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.
• Automation & Integration : Develop automation using Python, Terraform, Ansible, and CI / CD pipelines to streamline observability workflows.
• Implement self-healing mechanisms and automated remediation for recurring reliability issues.
• Ensure integrations with enterprise platforms, including PagerDuty, ServiceNow, and Jira, to enhance incident, change, and problem management.
• Analytics & Reporting : Deliver dashboards and reporting that provide actionable visibility into system health, reliability, and costs.
• Track and report key metrics such as MTTA, MTTR, error rates, and cost per workload.
• Knowledge Sharing & Continuous Improvement : Create documentation, runbooks, and training to support adoption and consistency across engineering teams.
• Participate in post-incident reviews, applying lessons learned to refine monitoring strategies and prevent recurrence.
• Promote a culture of continuous learning, improvement, and observability adoption across the enterprise.
