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.

• Collaborate with cross-functional teams to assess current infrastructure and define future-state architecture.
• Evaluate and recommend tools and vendors for mainframe modernization initiatives.
• Ensure robust security and governance across hybrid environments, including encrypted data exchange and secure API design.
