The Senior Site Reliability Engineer (SRE) is a hands‑on role responsible for the availability, performance, and end‑to‑end observability of QSR digital platforms across Mobile (iOS/Android), Web, and POS systems.

This role is part of the Observability team and works closely with mobile, web, and backend engineering teams to ensure full visibility into customer journeys and user experience.

The focus is on building and operating Real User Monitoring (RUM), synthetic monitoring, and end‑to‑end telemetry correlation using Splunk and SignalFx, ensuring issues are detected before customer impact. This is not a monitoring‑only role—it requires active involvement in instrumentation, release observability, and reliability engineering.

Key Responsibilities:

Define and enforce SLIs, SLOs, and error budgets for critical customer journeys (ordering, checkout, payments)

Own end‑to‑end observability across Mobile, Web, and POS platforms

Implement and operate RUM and synthetic monitoring for customer‑facing journeys

Build mobile‑first monitoring coverage including app performance, crash rates, API performance, and user journey tracking

Use Splunk and SignalFx to design dashboards, detectors, and actionable alerts

Enable correlation across mobile CDN API backend systems using logs, metrics, and traces

Partner with engineering teams for instrumentation, SDK integration, and embedding observability into releases

Analyze telemetry to detect post‑release issues, device/OS‑specific failures, and network degradation

Lead response for P1/P2 incidents and drive root cause analysis

Automate operational toil and improve reliability

Required Skills:

Strong experience with Splunk (logs, dashboards) and SignalFx (metrics/APM)

Hands‑on with RUM and synthetic monitoring tools

Experience with mobile observability (iOS/Android), including performance monitoring and crash analysis

Strong understanding of distributed systems and microservices (Java, Node.js)

Experience with Azure (AKS, App Services, APIM)

Ability to correlate frontend issues with backend services

Experience with CI/CD pipelines and observability in release processes

What Success Looks Like:

Clear visibility into mobile, web, and POS customer journeys

Issues identified before customer complaints or app store feedback

Reduced crash rates, latency, and checkout failures

Observability embedded into every release
