Job description

This role serves as an intermediate-level application support position, bridging day-to-day operational support and more advanced troubleshooting. The Application Support Analyst II supports applications built on a C#/.NET backend, Angular/TypeScript front end, and data services using Cosmos DB, SQL Server, Azure Service Bus, and Azure Functions. You will handle moderately complex investigations, take ownership of key support workflows, assist with onboarding and monitoring efforts, and collaborate closely with senior analysts and engineering teams to maintain platform stability.

• Manage support tickets for internal and client-facing applications, including custom C#/.NET + Angular systems and supporting business tools.
• Troubleshoot application issues across the stack (UI, API, data, and Azure services), resolving most incidents independently and escalating complex cases when needed.
• Monitor inbound and outbound data feeds, message queues, and Azure Functions to ensure reliable processing and delivery.
• Analyze SQL Server and Cosmos DB issues, identifying common scripts as needed and implementing them to help solve end user issues.
• Perform client onboarding tasks with minimal guidance—configuring feeds, validating integrations, and confirming successful initial data loads.
• Assist with root-cause analysis (RCA) for recurring issues and contribute to corrective and preventive action plans.
• Help maintain and improve monitoring, alerting, and operational dashboards.
• Create and maintain documentation, support procedures, and knowledge-base articles.
• Provide guidance to junior analysts on troubleshooting approaches, logging analysis, and platform behavior.

Qualifications

• Strong working knowledge of SQL, including writing complex queries, troubleshooting performance issues, and understanding execution plans.
• Practical experience reading and troubleshooting applications built with C#/.NET, Angular/TypeScript, or similar technologies.
• Solid understanding of relational data concepts, data flows, and message-driven processing.
• Hands-on experience with Azure services.
• Familiarity with application logging, monitoring, and diagnostics (e.g., Application Insights or similar platforms).
• Ability to manage multiple support tickets independently and prioritize work effectively.
• Strong communication skills, with the ability to clearly explain technical issues to technical and non-technical stakeholders.
• Demonstrated problem-solving skills and comfort handling moderately complex production issues in a fast-paced environment.
