What they are looking for :

They are looking for a senior integration developer who builds and maintains systems that pass data between applications using IBM App Connect Enterprise (ACE) and IBM Integration Bus (IIB).

They want someone to design and code message flows (ESQL, Java Compute Nodes, mappings), migrate older IIB work to ACE (modernize and containerize), connect to MQ / REST / SOAP / DBs / files / Kafka, and troubleshoot and tune performance. It also expects CI / CD deployments (Jenkins / GitHub Actions), logging / monitoring (Splunk / AppDynamics), security (auth / encryption), and clear technical docs.

In short — build, migrate, secure, and operate enterprise integrations; must know ACE / IIB, Java, ESQL, MQ, CI / CD, and ideally Docker / K8s and cloud.
