About the job

G-mass is collaborating with a distinguished global financial institution to find a seasoned Transaction Reporting Change & Release Lead. This individual will be responsible for managing the complete lifecycle of UK/EU transaction reporting changes, from regulatory interpretation to controlled production deployment.

This is a hybrid role that combines the responsibilities of a Technical Business Analyst with hands-on SQL and development tasks. You will serve as a vital link between Compliance, Operations, Risk, and Technology, converting regulatory requirements into actionable change specifications, overseeing release delivery, and enhancing production controls. A key goal is to minimize reliance on key personnel by standardizing documentation, runbooks, knowledge transfer, and repeatable release processes.

Please note that this role requires presence in the client’s London office (specific days to be confirmed).

  • Enhance documentation and knowledge sharing to reduce key person dependency and improve cross-functional understanding of reporting systems and logic.
  • Assist in designing and implementing more robust, scalable, and repeatable release processes for reporting changes.
