Senior Site Reliability Engineer
About the role
RADAR is hiring a Senior Site Reliability Engineer to own end-to-end reliability of its data infrastructure across 1,600+ live stores, lead incident response, run NOC operations, and build observability with defined SLIs/SLOs.
Responsibilities
- Own the incident management lifecycle end to end: detection, triage, escalation, communication, resolution, and postmortem for production incidents.
- Act as Incident Commander for high severity incidents, coordinating across engineering, support, and leadership until resolution.
- Run day-to-day NOC (Network Operations Center) operations, including 24/7 shift coverage, escalation matrices, and shift handover protocols.
- Coach and mentor NOC analysts on triage discipline and escalation judgment, and own NOC KPIs like response time and escalation accuracy.
- Design and maintain observability pipelines across metrics, logs, and traces, and define SLIs/SLOs with engineering and product.
- Build dashboards and alerts that surface true signal from sensor and platform data, reducing noise and alert fatigue.
- Facilitate blameless postmortems and root cause analysis, tracking corrective actions to closure.
- Maintain on-call rotations, runbooks, escalation policies, and report MTTA/MTTR/MTBF trends to leadership.
Qualifications
- 5+ years of experience in Site Reliability Engineering, DevOps, Infrastructure, or Production Operations with incident response and on-call experience.
- Experience running or contributing to a NOC, including shift scheduling, escalation processes, and performance metrics.
- Strong hands-on experience with observability tooling (Prometheus, Grafana, Datadog, New Relic, Splunk, ELK, OpenTelemetry, etc.).
- Solid understanding of SLIs, SLOs, SLAs, and error budgets, and how to use them to drive prioritization.
- Hands-on release engineering experience, including CI/CD pipelines, deployment automation, and safe rollout practices (canary releases, feature flags, automated rollbacks).
- Proficiency in at least one scripting or programming language (Python, Go, Bash, etc.).
- Experience with infrastructure-as-code tools (Terraform, Ansible).
- Experience with cloud platforms (AWS, GCP, or Azure) and container orchestration (Kubernetes, Docker).
- Clear, direct communicator who stays calm and organized under pressure during live incidents.
