ABOUT THE JOB

RADAR runs data infrastructure across 1,600+ live retail stores, processing tens of billions of real-world events every day. We’re hiring a Site Reliability Engineer to own the reliability of that system end to end — leading incident response, running day-to-day NOC operations, and building the observability foundation that lets us catch issues before they hit a store floor. You’ll be the steady hand during a live incident, and the engineer making sure there are fewer of them to begin with.

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 alert that surface true signal from our sensor and platform data, cutting down on noise and alert fatigue.
• Facilitate blameless postmortems and root cause analysis, and track corrective actions through to closure.
• Maintain on-call rotations, runbooks, and escalation policies, and report on MTTA/MTTR/MTBF trends to leadership.

ABOUT YOU

Required:

• You have 5+ years of experience in Site Reliability Engineering, DevOps, Infrastructure, or Production Operations, with direct incident response and on-call experience.
• You have experience running or actively contributing to a NOC, including shift scheduling, escalation processes, and performance metrics.
• You have strong hands-on experience with observability tooling (Prometheus, Grafana, Datadog, New Relic, Splunk, ELK, OpenTelemetry, or similar).
• You have a solid understanding of SLIs, SLOs, SLAs, and error budgets, and how to use them to drive prioritization.
• You have hands-on release engineering experience, including CI/CD pipelines, deployment automation, and safe rollout practices like canary releases, feature flags, and automated rollbacks.
• You are proficient in at least one scripting or programming language (Python, Go, Bash, etc.).
• You have experience with infrastructure-as-code tools (Terraform, Ansible).
• You have experience with cloud platforms (AWS, GCP, or Azure) and container orchestration (Kubernetes, Docker).
• You are a clear, direct communicator who stays calm and organized under pressure during live incidents.

Preferred:

• You have experience building or scaling a NOC from the ground up.
• You have a background in distributed systems architecture and microservices troubleshooting.
• You have familiarity with chaos engineering and resilience testing.
• You have a certification such as AWS Certified SysOps Administrator, Google Professional Cloud DevOps Engineer, or ITIL.

• Learn RADAR’s mission, technology stack and core values.
• Complete onboarding and security compliance training.
• Shadow the NOC across shifts and review recent incident history and open postmortem action items.

In your first 60 days, you will:

• Take on-call as primary or secondary responder for at least one service area.
• Tune or consolidate at least one high-volume, low-signal alert source, and audit existing observability coverage for major gaps.

In your first 90 days, you will:

• Lead Incident Commander duties for high severity incidents, including full postmortem facilitation.
• Deliver a reliability report on incident trends, NOC KPIs, and observability maturity gaps.
• Present a roadmap for the next 2–3 quarters covering NOC process, Automation, SLO definitions, and observability investment.
