EI Support Engineer - IBM

About the role:

Brainsquare is expanding its offshore support capacity within a dynamic international environment supporting complex enterprise integration landscapes.
We are looking for an experienced Enterprise Integration (EI) Support Engineer with hands-on experience supporting enterprise IBM Broker environments based on IBM App Connect Enterprise (ACE), IBM Integration Bus (IIB), and IBM MQ. The ideal candidate can quickly become productive in an existing enterprise integration landscape without requiring extensive onboarding or technical training.

You will be part of an international team responsible for ensuring stability, performance, and incident resolution for mission-critical integrations built on IBM middleware technologies.

Key Responsibilities:

• Monitor, troubleshoot, and resolve integration issues within IBM App Connect Enterprise (ACE) and IBM MQ environments.

• Support and maintain existing IBM Broker (ACE/IIB) message flows, integration servers, and enterprise messaging components within a production environment.

• Perform root-cause analysis and implement corrective actions for failed message flows or queue connectivity problems.

• Quickly understand existing Broker implementations and contribute to incident resolution with minimal ramp-up time.

• Collaborate closely with application and infrastructure teams to maintain interface health and ensure SLA compliance.

• Handle incident, service request, and change management via ITSM tools such as ServiceNow or Jira Service Management.

• Deploy and configure message flows, bar files, and integration servers in DEV, TEST, and PROD environments.

• Maintain system documentation and provide operational runbooks for recurring support cases.

• Proactively monitor message queues, memory usage, and broker performance, and suggest automation or alerting improvements.

Required Skills and Experience:

• 3–6 years of experience in enterprise integration or middleware support.

• Strong hands-on experience supporting IBM App Connect Enterprise (ACE), IBM Integration Bus (IIB/Broker), and IBM MQ within enterprise production environments.

• Previous experience maintaining existing Broker (ACE/IIB) integration landscapes rather than only developing new integrations.

• Ability to work independently in an established enterprise integration environment with minimal technical onboarding.

• Good understanding of message flow architecture, ESQL, and integration node administration.

• Knowledge of SOAP, REST, JDBC, XML, JSON, and HTTP/S protocols.

• Familiarity with Linux environments, shell scripting, and deployment automation.

• Experience with ticket handling and incident management (ServiceNow, Jira Service Desk).

• Excellent analytical and communication skills in English.

Nice-to-have skills:

• Experience supporting large enterprise integration platforms with high-availability and SLA-driven operations.

• Knowledge of cloud or containerized deployments (Docker, Kubernetes, OpenShift).

• Experience working with DevOps concepts (CI/CD pipelines, Git, Jenkins).

• Prior experience in an offshore support or shared-service environment.

What we offer

• Opportunity to work in a Belgium–India collaboration model on enterprise-grade IBM integration platforms.

• A stable, long-term role with growth opportunities in architecture or DevOps directions.

• Exposure to modern middleware and hybrid integration projects.

• A collaborative work culture that values ownership and technical excellence.

• Competitive compensation aligned with your skills and experience.
