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 SolarWinds.
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.
What You’ll Work On:
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
What We’re Looking For:
Bachelor’s degree in a technical field or equivalent practical experience
5+ years of experience in SRE, DevOps, or platform engineering roles
Deep hands-on experience with the ELK Stack – Elasticsearch cluster operations, Logstash pipeline d
