At Jefferies, the IT team is increasingly a source of revenue and competitive advantage for one of the fastest growing investment banking firms in the world. Our team of business technologists enable Jefferies’ sales, trading, research and banking colleagues to solve problems and seize opportunities with more speed and precision than ever before.  We deploy and manage the technology that keeps Jefferies running and our colleagues connected. We develop applications and tools to seamlessly serve Jefferies’ clients. We enhance business outcomes with AI and machine learning tools that uncover actionable insights from millions of data points from around the world.  We believe the strength of Jefferies always has been and always will be its people.

We want curious and creative people eager to push the boundaries of what they can do and passionate about using technology to solve problems and deliver better outcomes for our business. There are no silos, no lanes to stay in, and we don’ want people managing and executing the same narrow set of tasks each day.
  • A No Corner Office Culture: At Jefferies, you’ll find our business technologists working right alongside traders, researchers investment bankers, and sales teams. That’s how our technologists develop expertise about how trades work, how transactions are cleared, how clients are served, which data really matters, and how and why equity, fixed income and private markets move. When you join Jefferies, you will develop the financial market savvy necessary to build the platforms and the cutting edge applications that keep Jefferies one step ahead of our competitors.
  • A Chance to Unlock the Power of Big Data: Now, and in the years ahead, our businesses technologists will be leading Jefferies’ wholesale move into cloud computing. We will increasingly be building native applications in the cloud and using AI and machine learning tools to translate data into actionable insights, to automate more functions, to make Jefferies operations more secure and client service more seamless.
  • A Team of Builders and Problem Solvers: At some larger companies, the IT team’s primary role is maintaining legacy technology systems that are so sprawling and ingrained in the business that it’s difficult to transition to something new. But Jefferies is different. We’re growing fast, breaking into new markets and regions and we’re often building new technology platforms from the ground up. We have people from all across the business coming to us to answer their most mission-critical questions.  Technology is inevitably key to answer these questions. And as a business technologist, it’s up to you to deliver the right solution at exactly the right moment.
