Application Support Analyst
Location: Dallas, TX or Chicago, IL- Hybrid onsite 3 days a week
Employment Type: Full Time
Compensation: 50-60/hour

The Planet Group has partnered with a Dallas area company to locate a Senior Application Support Engineer to serve as a technical expert and escalation point for complex issues affecting business-critical applications. This position is ideal for a naturally curious problem solver who enjoys investigating unfamiliar systems, uncovering the source of difficult technical problems, and working across teams to implement lasting solutions.

The Senior Application Support Engineer will use SQL, application logs, code analysis, and advanced troubleshooting techniques to diagnose production issues, validate software defects, and perform thorough root cause analyses. This individual will collaborate closely with Product, Development, and other technical teams while providing guidance to less-experienced support engineers.

This is not a traditional help desk position. The successful candidate will be comfortable looking beyond surface-level symptoms, examining how applications, databases, APIs, and integrations work together, and taking ownership of issues through resolution.

This is a hybrid role and requires candidates to be onsite three days a week in either the Dallas area office or downtown Chicago.
