You'll step in as a DevOps & Technology Controls Engineer, working closely with payments and engineering teams, L1 support, DBAs, and stakeholders across the globe to own the reliability, change delivery, and operational excellence of complex payment infrastructure spanning IBM WebSphere Application Server, IBM MQ, Oracle, Kubernetes microservices, and SFTP integrations. Your role will be central to platform availability, CI/CD pipelines, incident management, security patching, and service governance – not just execution.
