• Respond within 30 minutes and resolve within 4 hours for High incidents (service slowness or partial instability).
• Respond within 1 hour and resolve within 8 hours for Medium incidents (small user subset affected, non-critical service).
• Respond within 2 hours and resolve within 24 hours for Low incidents (minor bugs, UX issues, non-critical errors).
• Manage AppDynamics monitoring dashboards, including configuring alerts, proactively detecting anomalies, and taking action before incidents impact users.
• Perform root cause analysis (RCA) for all Critical and High incidents, producing formal Arabic RCA reports within agreed timeframes.
• Manage the on-call rotation schedule, ensuring personal reachability after hours and on weekends for Critical incidents, as this is a contractual obligation.
• Coordinate with DBA and infrastructure teams for incident resolution across application, database, and server layers.
• Continuously maintain the incident log, problem register, and the updates/patches register.
• Write, maintain, and regularly validate Standard Operating Procedures (SOPs) and runbooks in Arabic for all recurring support scenarios, incident types, and recovery procedures.

• A minimum of 10 years of professional technical support experience, with at least 5 years at an L2/L3 level for enterprise .NET applications.
• Demonstrable experience with SQL Server production troubleshooting.
• Proven experience with log analysis and root cause analysis in production environments.
• Experience coordinating across application, database, and infrastructure teams during incidents.
• ITIL Foundation certification is preferred.

Required Technical Skills

• Expertise in L2/L3 .NET application support, including diagnosing production issues in .NET Core REST APIs and **** WebForms applications, reading .NET stack traces, application logs, and event logs.
• Proficiency in Windows Server administration, including IIS configuration and troubleshooting (application pools, bindings, request tracing), Windows Event Log analysis, and performance counters.
• Strong SQL Server troubleshooting skills, including blocking queries, deadlocks, long-running queries, plan cache issues, and SQL Server error logs; capable of DBA-level diagnosis.
• Advanced log analysis skills across Windows Event Log, IIS logs, .NET application logs, and structured logging output, with the ability to correlate logs across multiple layers.
• Experience with AppDynamics (or equivalent APM) monitoring dashboards, including configuration, custom alert setup, performance baseline management, and transaction tracing.
• Solid understanding of incident and problem management within the ITIL framework.
• Fundamental network knowledge, including DNS resolution, load balancer behavior, and firewall rules.

• Proficiency with secure remote access tooling and practices.

Professional Attributes

• Exceptional composure under pressure, maintaining a calm, structured, and solution-focused approach during critical incidents.
• Ability to provide clear and concise incident communication in Arabic to client stakeholders.
• Strong documentation discipline, ensuring every incident is recorded, every RCA is filed, and every runbook is updated.
