Job description

Who We Are

At Kyndryl, we design, build, manage and modernize the mission-critical technology systems that the world depends on every day. So why work at Kyndryl? We are always moving forward – always pushing ourselves to go further in our efforts to build a more equitable, inclusive world for our employees, our customers and our communities.


The Role

As a System Administrator at Kyndryl, you’ll solve complex problems and identify potential future issues across the spectrum of platforms and services. You’ll be at the forefront of new technology and modernization, working with some of our biggest clients – which means some of the biggest in the world.

Operational Support & Administration

  • Monitor and support day‑to‑day mainframe storage operations across z/OS environments.

  • Install, configure, maintain, and support z/OS storage software products (DFSMS, FDR, DFDSS, etc.).

  • Manage catalog structures, storage definitions, and hardware configuration definitions (HCD).

  • Provide on-call support and collaborate with cross-functional teams to resolve incidents, service requests, and change activities.

Engineering & Technical Delivery

  • Implement and support mainframe disaster recovery solutions, including GDPS, XRC, PPRC, and replication-based technologies.

  • Troubleshoot performance issues using z/OS tooling (SMF, RMF, GTF) and storage monitoring tools.

  • Administer enterprise-class storage platforms (IBM, HDS) and virtual tape systems (IBM TS7700, Oracle VSM7).

  • Perform data migrations using tools such as TDMF.

Quality, Documentation & Continuous Improvement

  • Develop and maintain operational procedures, installation guides, and platform standards.

  • Recommend improvements to enhance storage security, performance, and reliability.

  • Contribute to training, knowledge sharing, and cross-skilling within the team.

Your future at Kyndryl
Every position at Kyndryl offers a way forward to grow your career, from Junior System Administrator to Architect. We have opportunities for Cloud Hyperscalers that you won’t find anywhere else, including hands-on experience, learning opportunities, and the chance to certify in all four major platforms. One of the benefits of Kyndryl is that we work with clients in a variety of industries, from banking to retail. Whether you want to broaden your knowledge base or narrow your scope and specialize in a specific sector, you can find your opportunity here.


Who You Are

You’re good at what you do and possess the required experience to prove it. However, equally as important – you have a growth mindset; keen to drive your own personal and professional development. You are customer-focused – someone who prioritizes customer success in their work. And finally, you’re open and borderless – naturally inclusive in how you work with others.

Required Skills & Experience

  • 10+ years experience working with z/OS technologies as a Systems Administrator or Systems Programmer.

  • 10+ years experience with CICS and CTG in enterprise z/OS environments.

  • 10+ years experience with:

    CICS configuration, installation, maintenance, and performance tuning

    WebSphere (WAS) and MQ Series in z/OS environments

    TSO/E, ISPF, SDSF, JCL, and IBM mainframe utilities

    Debugging and monitoring tools such as IPCS, RMF, SMF, and ITCAM

  • Extensive experience performing CICS version upgrades, fix pack deployments, and lifecycle maintenance.

  • Strong experience supporting and administering MQ subsystems.

  • Proven ability to troubleshoot complex CICS/MQ performance and availability issues.

  • Excellent communication skills with the ability to collaborate effectively across technical and non-technical teams.

  • Demonstrated ability to manage priorities independently and meet deadlines in large, multi-stakeholder environments.

Preferred Qualifications

  • Experience with CICSPLEX System Manager.

  • Background in CICS dynamic routing and workload management.

  • Experience customizing CICS and developing IBM Assembler programs.

  • Experience developing and packaging SMP/E USERMODS, PTFs, and Functions.

  • Participation in Disaster Recovery or Business Continuity exercises involving CICS, WAS, and MQ on z/OS.

  • Experience supporting large-scale federal government or enterprise mainframe operations.

  • Experience delivering knowledge transfer and mentoring technical teams.


Being You

Diversity is a whole lot more than what we look like or where we come from, it’s how we think and who we are. We welcome people of all cultures, backgrounds, and experiences. But we’re not doing it single-handily: Our Kyndryl Inclusion Networks are only one of many ways we create a workplace where all Kyndryls can find and provide support and advice. This dedication to welcoming everyone into our company means that Kyndryl gives you – and everyone next to you – the ability to bring your whole self to work, individually and collectively, and support the activation of our equitable culture. That’s the Kyndryl Way.


What You Can Expect

Kyndryl cares about your well-being and prides itself on offering benefits that give you choice, reflect the diversity of our employees and support you and your family through the moments that matter – wherever you are in your life journey.
