- Troubleshoot complex production issues, ensuring reliability and performance of mission-critical systems.
- Collaborate with cross-functional teams on analysis, design, testing, and implementation of solutions.
- Leverage IBM's new zDIH technology to improve data integration, analytics accessibility, and modernization initiatives.
- Receive mentoring from our most senior engineers-experts with decades of mainframe experience-and progressively mentor junior team members.
- Participate in code reviews, architecture discussions, and continuous improvement of engineering practices.
