**Introduction** At IBM, work is more than a job - it's a calling: To build. To design. To code. To consult. To think along with clients and sell. To make markets. To invent. To collaborate. Not just to do something better, but to attempt things you've never thought possible. Are you ready to lead in this new era of technology and solve some of the world's most challenging problems? If so, lets talk. **Your role and responsibilities** The IBM Cloud Databases (ICD) team is responsible for developing, running, and operating the Software as a Service (SaaS) offerings that provide Database as a Services (DBaaS) in IBM Cloud. ICD is seeking an expert in PostgreSQL that is knowledgeable in internal concepts, such as database clustering, replication, and performance. The expert will work within our site reliability engineering organization to debug, troubleshoot, and resolve complex database clustering, performance, and replication issues. The expert will also work with clients to understand application usage patterns and share their expertise in application design and data model/query/connection optimization to get the maximum reliability and performance from their database. The expert will also work with our development team to design and provide ongoing feedback as we build new capabilities for our service. The expert will contribute to runbooks and external documentation. Programming skills are nice to have, but not required for this role. This is a good role for someone who might possess foundational programming skills and would like to hone those skills by contributing to the core service, tooling leveraged by our team to diagnose and respond to operational alerts, monitoring, metrics, and test cases.
