Role Overview
Liquidnet is looking for a senior level FIX specialist to manage client connectivity to our fixed income trading systems. The team requires a motivated self-starter with strong project management and technical skills to support existing FIX and proprietary API connections and help drive the direction of client connectivity to all Liquidnet Fixed Income trading platforms. This is a hands-on role where the client will utilize their deep understanding of Fixed Income FIX workflows, strong database, Linux and Windows Server knowledge to manage all aspects of client connectivity.

The successful candidate should possess a positive ‘can-do’ attitude and an intuitively high level of customer service in their approach. This will complement strong FIX, database (MYSQL), as well as Windows Administration and Networking troubleshooting skills (which may also involve firewall/routing issues).
