Affinia is the UK's fastest growing purpose-led, purpose-built Accountancy firm, focused on building stronger, more valuable relationships. With over 1000 colleagues across the East, South East, London and the Midlands, we are dedicated to supporting our clients, colleagues and communities.

We advise businesses, public sector organisations, charities and individuals throughout the UK and internationally across six Service Lines – Accounts Solution, Taxation, Audit & Assurance, Corporate Finance, Payroll and Corporate Recovery, supported by centralised enabling functions spanning People, Finance, Marketing, Business Support, IT, Risk and Corporate Development. Our team also offer in-depth sector expertise across a number of sectors, ensuring our clientsreceive the best short to medium and long-term advice, tailored to them.

We are committed to delivering excellence in every aspect of our work, adapting to the evolving technology and regulatory landscape while consistently exceeding client expectations.

Our people are our most valuable asset. We are therefore committed to supporting our colleagues throughout their professional development, providing guidance and training at whatever stage of their career they join us.

As a Director within both 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.

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.
