Electronic trading specialist

Background

The E-Fixed income Development Team is responsible for implementing low latency, high performance and real-time electronic trading systems. The team has recently completed the replacement of a legacy Java Swing UI with a suite of apps based on the OpenFin/Here platform and React/JS. A React specialist is required to help grow and maintain the shared app framework and component library, ensure a consistent and intuitive UX across the suite of apps and work on new business-facing deliverables.

Summary

The developer will join the eFI team as a React/JS expert, working to extend and improve the key capabilities of our apps, and assisting colleagues with less front-end experience in delivering new features.

The business is ever changing and demands an agile development culture. The candidate must have a proven track record of being able to work in a highly dynamic environment with demanding clients and aggressive schedules. The successful candidate will gain excellent exposure to these business areas as well as the opportunity to work in a technically challenging, delivery-focused environment.

While maintenance of the existing platform and interaction with the various eFI teams is a key part of the role, there is also the opportunity to shape the future of the platform through projects and ongoing business requirements.
