This engineer will be responsible for reliability, availability, security, performance, and recoverability across production and non-production environments.

The position is well suited to an experienced middleware engineer who wants broad platform ownership rather than being limited to one product.

• Own middleware availability, disaster recovery, failover, monitoring, and operational readiness.
• Configure IBM MQ queue managers, queues, channels, clusters, security, certificates, and routing.
• Troubleshoot complex messaging, application-integration, connectivity, and performance issues.
• Lead platform upgrades, patching, capacity planning, lifecycle management, and vulnerability remediation.
• Develop automation for deployment, monitoring, configuration, and recurring operational activities.
• Partner with application, network, security, infrastructure, DevOps, and production-support teams.
• Support business-critical integrations with external financial institutions and market-infrastructure providers.

Role Requirements

• 5+ years of enterprise middleware or messaging-infrastructure experience.
• Strong hands-on IBM MQ administration and troubleshooting.
• Working knowledge of both Apache Kafka and RabbitMQ.
• Experience designing high-availability and disaster-recovery solutions.
• Strong Linux or Unix administration skills.
• Understanding of TCP/IP, DNS, firewalls, load balancing, certificates, and TLS.
• Experience with monitoring and observability platforms.
• Scripting or infrastructure-automation experience.
• Strong production-support, incident-management, and root-cause-analysis skills.
• Ability to independently troubleshoot complex distributed systems.

PREFERRED EXPERIENCE

• Financial-services, brokerage, trading, banking, clearing, or fintech experience.
• AWS or other public-cloud experience.
• Experience with financial-market infrastructure integrations.
• Docker or Kubernetes.
• Infrastructure as Code.
• Relevant IBM MQ, Kafka, Linux, AWS, cloud, or security certifications.
