Senior Application Support Engineer (Integration & Middleware)

The Integration Support team is responsible for the health and reliability of the enterprise middleware layer. The L2 Application Support Engineer will manage complex data flows between systems, ensuring that Spring Boot services and IBM CP4I components (MQ, ACE, APIC) are performant, secure, and highly available.

Role Objectives:

• End-to-End Traceability: Trace transaction flows from the API Gateway (API Connect) through the Enterprise Service Bus (ACE) to the backend Microservices (Spring Boot).
• Root Cause Analysis (RCA): Conduct deep-dive investigations into middleware failures, including message losses in MQ, synchronization errors in ACE, or JVM crashes in Spring Boot.
• Platform Governance: Oversee the stability of integration components running on Red Hat OpenShift, ensuring optimal resource allocation and pod scaling.
• Security Enforcement: Manage and troubleshoot security protocols, including Mutual TLS (mTLS), OAuth2, and JWE/JWS within the integration layer.

Detailed Technical Responsibilities:

1. IBM Cloud Pak for Integration (CP4I): Troubleshoot message flows, ESQL logic errors, and adapter connectivity issues (SAP, Database, File).
2. IBM MQ: Manage queue managers, resolve channel retries, and investigate dead-letter queues.
3. API Connect: Resolve issues related to API definitions, security policies, and latency.
4. Backend Microservices (Spring Boot): Analyze performance and debug connectivity issues with databases and external messaging systems.

Technical Skill Set:

• Integration Platforms: Mastery of IBM CP4I (ACE, MQ, API Connect).
• Development Frameworks: Advanced knowledge of Java and Spring Boot.
• Containerization: Expert-level proficiency in Red Hat OpenShift and Kubernetes.

• Education: Bachelor’s degree in Computer Science, Software Engineering, or a related field.
• Certifications (Preferred): IBM Cloud Pak for Integration Specialist, Red Hat Certified Specialist in OpenShift Administration.

Key Performance Indicators (KPIs):

• Integration Uptime: Achieving 99.99% availability for critical middleware components.
• L2 Resolution Rate: Maximizing the number of integration issues resolved without escalation to L3 Engineering.
• MTTR: Reducing failure identification and fix times in the message delivery pipeline.
