*Support order flow, execution pipelines, market data feeds, and trade lifecycle processes
*Build automation and tooling that eliminates repetitive manual operations
*Improve monitoring, observability, and alerting across the stack
*Participate in on-call and out-of-hours incident response


Key skills

*Linux / Unix environments
*SQL for investigation and debugging
*Production incident troubleshooting
*Monitoring tools - Geneos, Splunk, Dynatrace
*Scripting and automation - Python, Bash


Highly valued experience

*FIX protocol
*Exchange connectivity and market data systems
*Messaging systems - Kafka, Solace, Tibco, MQ
