You will find Intermedia is a place where you can indulge your passion for creating and supporting great cloud technology.
About the role: We are looking for an SRE to improve reliability and operational readiness with a strong focus on metrics, alerting, and event management. You will build and maintain monitoring using Prometheus/VictoriaMetrics, integrate alerts and events with BigPanda, and participate in on‑call rotations to drive fast incident response and continuous improvement across Windows and Linux environments.
Key Responsibilities
- Build and operate metrics/monitoring platforms: Prometheus and/or VictoriaMetrics (scrape configs, exporters, recording rules)
- Design and maintain alerting strategy: thresholds, anomaly detection where applicable, alert routing, deduplication, and noise reduction
- Integrate monitoring/alerting and events with BigPanda (correlation, enrichment, routing, incident workflows)
- Create and maintain dashboards and operational visibility (Grafana or equivalent)
- Develop and maintain runbooks, operational playbooks, and incident response procedures
- Participate in on‑call shifts: triage alerts, manage incidents, coordinate response, and lead communication during outages
- Perform root‑cause analysis, postmortems, and implement corrective/preventive actions
- Improve service reliability via SLOs/SLIs, capacity planning, and automation to reduce toil
- Support monitoring for core infrastructure and services on Windows and Linux, including HA components and clusters
- Collaborate with DevOps/Engineering to instrument applications and standardize telemetry (metrics, logs, traces where applicable)
Skills, Knowledge and Expertise
- Experience in SRE / Operations / DevOps with production incident ownership
- Hands‑on experience with Prometheus and/or VictoriaMetrics (exporters, alert rules, recording rules, troubleshooting)
- Experience integrating alerting/event pipelines with BigPanda (or similar event correlation tools)
- Strong troubleshooting skills across Linux and Windows systems (networking, OS, services)
- Ability to build reliable alerting with minimal noise (correlation, grouping, suppression, maintenance windows)
- Experience with Git‑based workflows for monitoring‑as‑code and configuration management
Nice to Have
- Grafana administration and dashboard design standards
- Log management (ELK/EFK, Loki) and/or tracing (OpenTelemetry)
- Automation skills (Python, PowerShell, Bash) and configuration tools (Ansible)
- Messaging/cache/proxy operations: RabbitMQ, Redis, Nginx
- Experience with Windows clustering or HA environments
- Experience defining SLOs/SLIs and operational KPIs
- Experience in managing VOIP components and protocols (SIP, FreeSwitch, OpenSIP, session border controllers)
- Experience with load balancing components (F5 LTM, F5 GTM)
- Experience with virtualization platforms such as VMWare or HyperV
- Experience with administering AWS or Azure tenants
On-call Expectations
- Participation in a rotating on‑call schedule (including nights/weekends as needed)
- Ownership of incident response: rapid triage, escalation, mitigation, and follow‑up improvements
- Commitment to improving monitoring quality to reduce alert fatigue and improve MTTR
