Key responsibilities include:

• Developing and maintaining systems supporting trade capture, reconciliation, settlement, risk, treasury, P&L, and regulatory reporting
• Partnering with Operations and Finance to automate workflows and reduce errors
• Building integrations with external systems such as prime brokers, fund administrators, custodians, and regulatory platforms
• Making architectural decisions that will support the fund’s rapid growth and long-term reliability
