This role provides senior leadership, strategic oversight and full commercial accountability for a portfolio of key FNZ clients, combining direct client ownership with leadership of Client Directors and matrixed delivery teams to drive sustainable revenue growth, margin performance, disciplined P&L management and exceptional client outcomes.

The Head of Client Relationships is accountable for the overall performance, growth, profitability and strategic development of a portfolio of FNZ clients. Operating as a player/coach, the role combines executive ownership of FNZ’s most strategic client relationships with leadership of Client Directors responsible for day‑to‑day account delivery, commercial performance and client advocacy.
The role provides strategic oversight across multiple clients, ensuring consistent, high‑quality delivery of the FNZ platform services, alignment to FNZ’s go‑to‑market strategy, and achievement of financial, operational, regulatory and customer satisfaction outcomes. This includes ownership of portfolio P&L performance, revenue retention, growth pipeline, margin protection, cost‑to‑serve discipline and resolution of commercial risks.
The role holder acts as the senior client sponsor for priority accounts, executive escalations and commercial outcomes, while coaching and developing Client Directors to deliver predictable, scalable performance across the client portfolio, build trusted relationships with client executive teams, Boards and senior stakeholders, and create a high‑engagement culture that improves both client and colleague advocacy.
The Head of Client Relationships works in close partnership with Service Delivery, Portfolio, Product and Commercial leadership to create a single, joined‑up client view across relationship, commercial and delivery performance. The role is expected to operate hand‑in‑glove with the Delivery organisation, ensuring that client commitments, delivery capacity, change priorities, service performance and operational risk are reviewed collectively and acted on with clear ownership, pace and discipline.
