We're supporting a global financial services organisation on a major derivatives OMS migration programme, driving the transition to a new trading platform within a highly regulated environment.

This is a business critical transformation, focused on delivering a clear roadmap, ensuring strong governance, and enabling a smooth migration from legacy systems into a modern OMS landscape.

• Managing governance, reporting and stakeholder engagement across business and technology teams
• Identifying and mitigating risks, ensuring smooth delivery within a regulated trading environment

• Experience working across Front Office, Risk, Operations and Technology stakeholders
• Strong governance, risk management and reporting capabilities
• Comfortable operating within structured and regulated environments

This is a high impact opportunity to lead a core trading systems transformation, working with senior stakeholders and shaping the future operating landscape of a major financial institution.
