Description

At Apple, we don’t just build products — we craft experiences that enrich people’s daily lives. The Application Production Support (APS) & Site Reliability Engineering (SRE) team is responsible for ensuring that mission-critical enterprise systems and customer-facing cloud services operate with high availability, resilience, and performance at massive scale. We are seeking a motivated Junior Application Support & Site Reliability Engineer with 1 to 2 years of experience to join our fast-paced, agile engineering team. In this role, you will keep mission-critical applications running reliably across multiple environments—triaging production incidents and debugging application, database, core system, and performance bottlenecks through to root cause and permanent remediation. You will partner cross-functionally with development, QA, database, and infrastructure teams to resolve large-scale production disruptions, eliminate operational toil through automation, and manage platform health using modern observability and emerging GenAI technologies. This is an exceptional opportunity for an engineer with a strong foundation in Linux, relational databases, and programming who wants to build a deep, high-impact career in production and reliability engineering at Apple.

Responsibilities

High-Availability Operations: Monitor the health, performance, and capacity of mission-critical applications and services across multi-region environments. Incident Triage & Response: Act as a first-line responder to production alerts, outages, and system anomalies, participating in on-call rotations and rapid-response workflows. End-to-End Troubleshooting: Investigate and debug complex application, core system, network, and performance bottlenecks through to resolution. Database Diagnostics: Perform database-level troubleshooting, query analysis, data verification, and performance tuning across PostgreSQL, Oracle DB, and MySQL environments. Root-Cause Analysis (RCA): Partner with development, QA, database, and infrastructure teams to identify underlying root causes and implement permanent fixes. Observability & Alerting: Build and refine telemetry dashboards, log aggregations, and alerting rules using tools such as Splunk, Prometheus, Grafana, and Dynatrace to eliminate blind spots. Service Level Tracking: Track and uphold key reliability metrics (SLIs/SLOs) to minimize Time to Detect (TTD) and Time to Mitigate (TTM). Toil Reduction & Automation: Develop robust scripts and tools (Python, Bash) to automate repetitive operational tasks, health checks, and routine maintenance. Release & CI/CD Enablement: Support production deployments, CI/CD pipeline runs (Jenkins, GitHub Actions), build validations (Maven, Gradle), and canary/smoke testing. Change & Configuration Governance: Execute production change requests (CRs) in accordance with enterprise change management and risk assessment standards. Continuous Improvement & Modern Tooling: Leverage modern engineering practices and GenAI-assisted workflows to accelerate log analysis, incident documentation, and operational efficiency.
