Senior Site Reliability Engineer - Observability

About the Role

We are looking for a Senior SRE to join our Platform Engineering team as the operations owner of our observability platforms. You’ll be responsible for the reliability, scalability, and continued evolution of the tools that give our engineering organization visibility into everything they build and run. The current observability platform is primarily comprised of on-premises ELK (Elasticsearch, Logstash, Kibana) Stack and Grafana, with some exposure to New Relic and Solar Winds.

This is a hybrid role: roughly half your time will be spent on steady-state operations and platform support, and the other half on engineering projects that meaningfully advance the platforms you support. It’s a great fit for someone who is genuinely motivated by the pursuit of excellence – not just sustaining what works but relentlessly refining it. You take pride in the platforms you own, and that pride drives you to keep improving them, whether that means tightening an SLO, eliminating a source of toil, or building something that gives teams faster insight into their systems.

Operations & Reliability (~ 50%)

• Serve as a primary escalation point for production support involving the ELK Stack, Grafana, and New Relic
• Own platform health, capacity planning, and performance tuning for on‑premises observability infrastructure – including Elasticsearch cluster management, index lifecycle policies, and retention strategies
• Monitor and maintain SLOs for the observability platforms, ensuring the tools engineers depend on are highly available and performant
• Support engineering teams in onboarding to observability platforms – helping teams instrument their applications, build dashboards, and define meaningful alerts
• Manage patching, upgrades, and configuration management across the observability stack
• Collaborate with security to harden platform configurations and manage software vulnerabilities
• Contribute to on‑call rotations and maintain runbooks and escalation procedures

Platform Engineering (~ 50%)

• Design and build tooling/automation to reduce toil and improve the experience for teams using observability platforms
• Lead or contribute to platform modernization initiatives – e.g., improving ingestion pipelines, scaling platform capacity, standardizing Grafana dashboard and alerting patterns, or evaluating new capabilities within the existing stack
• Develop and maintain infrastructure‑as‑code (Terraform, Helm, Ansible, etc.) for platform components
• Build and enforce standards around logging metrics and alerting that help engineering teams adopt observability best practices at scale
• Participate in design reviews and contribute to the overall platform roadmap

• Bachelor’s degree in a technical field or equivalent practical experience
• 5+ years of experience in SRE, Dev Ops, or platform engineering roles
• Deep hands‑on experience with the ELK Stack – Elasticsearch cluster operations, Logstash pipeline development, Kibana, and index lifecycle management
• Strong experience with Grafana, including data source integrations, dashboard design, and alerting
• Solid understanding of observability principles
• Experience operating on‑premises infrastructure, including capacity planning, server management, and the operational tradeoffs with managed cloud services
• Proficiency in Python for automation and tooling; familiarity with shell scripting
• Strong Linux systems knowledge and comfort working with configuration management tools (e.g., Ansible, Chef, Puppet, etc.)
• Demonstrated ability to drive incidents to resolution and communicate clearly under pressure
• A bias toward automation and a low tolerance for repetitive manual work

• Experience with Prometheus
• Experience with New Relic administration or APM instrumentation
• Familiarity with log shipping agents and pipeline tools such as Beats, Fluentd, or Fluent Bit
• Experience with distributed tracing tools like Open Telemetry
• Exposure to cloud‑based observability offerings and experience thinking through hybrid strategies
• Prior experience building or governing observability standards across a large engineering organization
