Job role - We are seeking a Db2 Data Engineer to join our Db2 Reliability Pod, a team focused on engineering resilient, highly available, and recoverable data platforms. This role is responsible for designing and automating reliability capabilities that ensure critical Db2-based services remain available, recoverable, and scalable.

Unlike a traditional Db2 Database Administrator (DBA) role, this position focuses on platform engineering, resilience, automation, observability, and data replication architecture, rather than routine database administration activities. The role aligns with reliability initiatives involving high availability, failover, replication, disaster recovery, and operational readiness.

Key Responsibilities

- Design and engineer high-availability, disaster recovery, and data replication solutions for Db2 environments.
