This is an exciting opportunity for a Senior Software Engineer who enjoys working at the intersection of critical mainframe systems and modern engineering practices. In this role, you’ll support highly visible platforms across Commercial Bank, Wealth, Private Banking, and Treasury while playing a key role in modernizing the mainframe ecosystem.
Beyond strong COBOL and Easytrieve skills, this position offers opportunity to lead the migration from legacy code management to devops pipeline transformation, automation, API enablement, cloud integration, and real‑time data streaming off the mainframe—work that has rarely been done in traditional mainframe environments.
You’ll collaborate closely with senior technical leaders and industry experts, contribute to new development and enhancements, and help shape the future of the platform by leveraging industry‑leading technologies such as IBM’s zDIH (z/OS Data Integration Hub). For an engineer passionate about mainframe technology who also wants to build future‑ready skills and have meaningful impact, this role offers both stability and innovation in equal measure.
