Application Support Engineer

Application Support Engineer We’re looking for an Application Support Engineer to join our Systems Operations team, reporting to the Senior Director, Systems Operations . In this role, you’ll provide hands-on operational support for critical Nasdaq applications and data-processing services. Working primarily in Linux/Unix environments, you’ll monitor production systems, investigate alerts and processing issues, manage operational work queues, respond to incidents, and help ensure services meet strict availability and processing SLAs.

This is a production-focused application support role rather than an infrastructure or service-desk position. You’ll work as part of a globally distributed operations team and collaborate with Development, Infrastructure, Client Services, exchanges, data vendors, network providers, and other technical teams. You’ll fit right in if you’re collaborative, methodical, comfortable working under pressure, and able to analyse information from multiple sources to identify what has failed, assess its impact, and determine the appropriate recovery or escalation path.

What You’ll Do Operate and support critical production applications and data-processing services in Linux/Unix environments. Perform real-time monitoring of application health, data flows, batch processing, alert generation, capacity, and service availability. Investigate monitoring alerts and production issues, restoring service where possible and escalating to the appropriate technical teams
