About the Role
Jari Solutions is seeking a Senior .NET Application Support Specialist (L2/L3) for an onsite position in Riyadh. This role is central to the operational stability of client production systems, particularly their correspondence system. The specialist will serve as the primary point of contact for system outages, requiring prompt and effective responses to minimize disruption. This position demands an active, always-available operational function that combines deep .NET and database troubleshooting expertise with meticulous documentation and clear communication with client stakeholders under pressure. The role carries significant Service Level Agreement (SLA) obligations.
Key Responsibilities
- Provide L2 and L3 technical support for production systems, serving as the primary escalation point for application-layer incidents beyond basic helpdesk support.
- Maintain mandated SLA tiers, including a 15-minute response and 2-hour resolution for Critical incidents (service outage affecting client operations).
- 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.
Qualifications and Experience
- Fluent Arabic speaker is a mandatory requirement.
- 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.
- Experience troubleshooting Identity Server issues, including SSO session problems and OpenID Connect flow debugging.
- Basic Oracle skills sufficient to read Oracle alert logs and identify tablespace issues.
- Awareness of DevOps pipelines and deployment processes.
- 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.
- Effective escalation judgment, knowing when to resolve independently versus escalating to higher tiers.
- High availability and reliability, understanding that on-call duties are a contractual obligation requiring consistent responsiveness.
