G MASS are supporting a large-scale contract reconciliation initiative driven by a recent acquisition and a transition to a new billing and pricing model. The programme aims to simplify long-standing, complex contract arrangements with major banking clients and move from hundreds of invoices per bank per year to a single consolidated monthly or quarterly invoice.
This is a hands-on, detail-oriented role embedded within a client experience team, sponsored by Finance, and working closely with Sales and Commercial stakeholders. It is well suited to someone early-to-mid career who enjoys investigative work, navigating systems, and bringing structure to complex information.
You will be supported by a broader delivery team providing validation, guidance, and escalation support, while being trusted to operate independently day to day. This role offers strong visibility across the organisation and the opportunity to grow with a complex, business-critical programme.
