• Define and maintain best practices, standards, and governance for Murex configuration and functional development.
• Architect and enhance simulation views used for P&L, Risk, Stress Testing, and valuation reporting.
• Design and oversee market data configuration including instruments, indices, curves, volatility surfaces, swap generators, and historical data structures.
• Lead the development, enhancement, and optimization of pre-trade and post-trade MSL formulas and workflows.
• Drive resolution of complex production issues impacting Front Office, Risk, Accounting, and Operations functions.
• Provide expert-level troubleshooting and configuration support for VaR, Stress Testing, and risk management frameworks.
• Partner with senior business stakeholders to understand strategic requirements, identify opportunities for improvement, and translate business needs into scalable Murex solutions.
• Lead impact assessments, solution design reviews, and functional architecture discussions for major initiatives.
• Mentor and guide engineers and analysts, fostering functional knowledge sharing and technical excellence across the team.
