To thrive in this role, you’ll need prior experience developing financing solutions at a bank or buy-side firm and strong relationships with prime brokers and counterparties across the spectrum of equity, ETF and corporate credit financing products.

This role is entrepreneurial—it offers the opportunity to shape and execute financing decisions and help develop the firm's long-term financing strategy.

  • Managing and negotiating our financing transactions on a day-to-day basis across various products
  • Maintaining and developing relationships with prime brokers and other external financing counterparties

  • Helping to form our long-term financing strategy by improving and expanding our current activity
  • Understanding our firmwide financing constraints and comparing financing opportunities using in-depth cost-benefit analysis
  • Helping to build and improve the infrastructure that supports our financing initiatives

About You

  • Have 3-5 years of relevant financing experience at a buy-side firm or bank
  • Have a strong understanding of EMEA financing and stock loan markets; having experience across multiple asset classes (e.g., equities, corporate bonds, ETFs) and financing structures (e.g., PB, swap, repo) is a plus
  • Excited and able to cultivate and manage relationships with prime brokers and other external financing counterparties
  • Have strong analytical skills and experience with performing technical data analysis to solve problems (e.g., through previous work experience, STEM coursework)
  • Intellectually curious and motivated to learn about new financing trade types and strategies
  • An effective communicator who works well in a team environment
