Collaborate with vendors and open-source communities to influence feature roadmaps and maximize platform value.Observability Engineering 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. 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 give both engineers and leadership actionable visibility into system health, reliability, and costs. Track and report key metrics such as MTTA, MTTR, error, 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. The key Moderna Mindsets you’ll need to succeed in the role : We behave like owners. You’ll be a self-starter who takes initiative and drives outcomes , going beyond assigned tasks to deliver platforms that create long-term value. We act with urgency. Action today compounds the lives saved tomorrow. You will proactively optimize observability tools and workflows to enhance system performance and reliability. We obsess over learning. We don’t have to be the smartest – we have to learn the fastest. In this role, you will continuously refine monitoring strategies based on real-time data and incident response learnings. Here’s What You’ll Need (Basic Qualifications) 7+ years of experience in site reliability engineering, observability, or platform engineering. Extensive expertise in managing and administering SaaS (Dynatrace, Splunk, or similar) or open-source observability platforms, including governance, agent fleet management, and cost optimization. Proven experience designing and building scalable, resilient, and cost-effective observability platforms using Prometheus, Grafana, Node / Blackbox Exporters, Kubernetes, or similar. Strong knowledge of observability practices (metrics, logs, traces, SLO / SLI design) across complex, large-scale enterprise environments. Hands-on experience with incident management platforms such as PagerDuty and ITSM integrations (ServiceNow, Jira). Proficiency in automation and infrastructure-as-code (Python, Terraform, Ansible, Bash). Experience monitoring and troubleshooting hybrid and cloud-native environments (AWS, Azure, or GCP). Strong problem-solving skills and the ability to operate in a high-paced, global environment. Demonstrated ability to take initiative, work independently, and drive outcomes in complex enterprise environments. Here’s What You’ll Bring to the Table (Preferred Qualifications) : Experience working in biotech, pharmaceutical, healthcare, or other regulated environments (e.g., GxP, HIPAA) Experience with enterprise-scale log management (e.g., Loki, Elastic, Splunk) and retention / cost optimization. Familiarity with ITSM processes and integrations with observability solutions. Relevant certifications in AWS, Azure, Dynatrace, Splunk or related observability technologies. A proactive, innovative mindset with a passion for open-source adoption, continuous improvement, and automation. At Moderna, we believe that when you feel your best, you can do your best work.
