A master’s degree in History isn’t the usual launchpad into mainframe computing. My academic life at the University of Edinburgh revolved around dusty archives and long hours with centuries-old texts. It often felt like I’d stepped out of the 21st century entirely. I loved it. The analytical skills I honed there still serve me every day. But technology wasn’t exactly part of the syllabus.
Still, mainframe computing was never completely foreign. Family members in the field had given me glimpses of this quiet giant of the tech world. When I started digging in on my own, I ran into the same myths everyone hears: mainframes are relics of a bygone era. But the more I researched, the clearer it became that these systems are anything but obsolete. They’re the invisible backbone of industries that keep the world running.
That realization sparked action. I dove into IBM’s Z Xplore program, brushing up on coding basics and exploring z/OS. When I spotted a LinkedIn post about Broadcom’s Mainframe Vitality Program, I felt ready to take the leap—and it turned out to be one of the best decisions I’ve ever made.
Intensive Training, Real Skills
The program kicked off with a three-month foundation in mainframe essentials: Z architecture, TSO, ISPF, and JCL. We moved on to REXX and COBOL, capping the phase with a final project that tied everything together. It was challenging, practical, and incredibly rewarding, with instructors who answered every question and pushed us to think critically.
Next came focused product training on OPS/MVS and CA7—tools I now use daily. That deep dive meant I could hit the ground running when the residency began.
Inside the Bank, and Into the Future
For the final stage, I joined one of Britain’s largest banks. Walking in on day one was nerve-racking, but my new colleagues welcomed me instantly. Their generosity with their time and knowledge has been invaluable, and it confirmed how collaborative and supportive this field can be.
Looking Back, Moving Forward
As my residency at the bank wraps up, I’m struck by how my background in history prepared me for this path. Critical thinking, attention to detail, and the ability to analyze complex information translate seamlessly to mainframe work. Combined with the rigorous training from the Vitality Program, I feel confident and excited for what comes next. Every day brings something new to learn and that’s exactly how I like it.
