At General Motors, we are committed to designing, building and selling the world's best vehicles with Zero Crashes, Zero Emissions, and Zero Congestion.

Globally, we have a significant presence in mainframe database infrastructure. As an IMS Mainframe Database Systems Programmer at GM, you will play a key role in deploying, managing, and supporting our global mainframe database systems. This includes working with various teams such as database vendors, infrastructure groups, DBAs, and application developers to ensure reliability, performance, and scalability of our mainframe database systems, including Db2 and IMS.

This position involves implementing best practices, optimizing performance, and maintaining consistency across GM's enterprise-wide mainframe database landscape. It also requires ensuring project learnings are documented and shared, solving assorted and involved DBMS issues, and providing technical support and input on the application of technology to a defined business segment.

We are seeking candidates who possess professional experience in this specific role and a Bachelor of Engineering/Arts/Science or equivalent degree in computer science or related area of study. The ideal candidate should provide global support for Db2 and/or IMS (Transaction and Database) products and Level 3/4 support for software delivery teams.

In addition, the successful candidate will be responsible for implementing part or all of the technical solution in accordance with an agreed technical design. They will also own and produce documentation, translate technical details into concise and easy-to-understand written form, and support systems in a 24x7 on-call rotation.

Key Responsibilities:
  • Implementing best practices, optimizing performance, and maintaining consistency across GM's enterprise-wide mainframe database landscape
  • Providing global support for Db2 and/or IMS (Transaction and Database) products and Level 3/4 support for software delivery teams
  • Implementing part or all of the technical solution in accordance with an agreed technical design
  • Owning and producing documentation
  • Supporting systems in a 24x7 on-call rotation

Furthermore, we require the candidate to possess knowledge of using Db2 and/or IMS commands to start and stop Db2 and/or IMS, and manipulate Db2 and/or IMS connections with other subsystems (including CICS, Db2, other IMS systems). They should also have past experience demonstrated zOS and associated product system installs, upgrades, de-installs, and application of maintenance.

The candidate should have a strong understanding of Db2 and/or IMS system internals and configuration, as well as vendor interaction experience (including experienced in searching their knowledge databases). Additionally, they should have familiarity with IT best practices (e.g., CMMI, ISO9000, ITIL, COBIT).
