Benefits

Additional Information

Our client, a Tier 1 global bank, is planning for the establishment of a Prime Brokerage business to serve institutional hedge fund clients. The initial focus covers equities, ETFs, and US Treasuries, with a client base of long/short equity, equity market neutral, and macro funds. The business will have to be built from the ground up within an existing bank infrastructure, which means the technology program involves both the deployment of new platforms and the extension of systems already in place. The Solutions Architect hired into this role will work for the client head of the prime brokerage program as one of the senior technical authorities for the program. This person will help to set the architecture for new platforms, determine how existing systems need to be modified or extended, participate in the vendor selection and integration, and ensure that the overall technology design is operationally sound from day one. The role carries real accountability and requires someone who has done this kind of work before in a comparable environment.
