Purpose of the role

As a Director within either our Personal or Corporate team, you will be responsible for continuing to grow our overall Tax offering within the firm both internally within the existing client portfolio but also externally through your own professional contacts and connections.

This role goes beyond technical tax oversight — it is a leadership position responsible for building high‑performing teams, developing future leaders, ensuring operational excellence, and helping shape the firm’s long‑term strategic direction. You will act as a key advisor to clients, supporting business development efforts and identifying opportunities to add value. Internally, you will oversee and mentor Managers and Senior Managers, role model the firm’s values, and contribute to service line strategy, operational projects, and change initiatives. You will take ownership of process improvements, risk management, and cross‑location collaboration, while supporting the Head of Tax in achieving team and firm‑wide objectives.

Accountabilities

You will be required to manage a comprehensive and complex client list, provide line and performance management and make a significant contribution to ongoing growth of a successful Tax practice. You will have a direct contribution to the development and achievement of building the practice and will be required to build and maintain relationships with third parties. You will be expected to advise clients in connection with their tax affairs and onboard them to the team to offer bespoke advice.

You should already be working as an experienced senior manager or Director and looking to develop your role considerably through technical advice, client management and business development.
