What you'll do:

As a Senior Manager International Tax, you will play a pivotal role in advising major UK-based and international clients on their most critical cross-border tax issues.

Your ability to balance technical excellence with commercial awareness will ensure you are well-positioned to thrive in this highly respected team.

Provide expert international tax advisory services to a varied portfolio of clients, supporting their commercial objectives through tailored solutions. Manage the delivery of technically robust advice on corporate tax structuring, refinancing strategies, business reorganisations, pre- and post-transaction planning, and legal structure optimisation. Oversee multi-jurisdictional projects involving international expansion, operating model redesigns, and responses to global tax policy changes such as BEPS 2.0. Support clients during tax authority enquiries by offering clear technical guidance and collaborating with specialists from other departments or overseas offices as needed. Coach and develop junior team members by sharing knowledge, offering feedback, and fostering an environment of continuous learning. Build strong relationships with clients by understanding their business needs and identifying opportunities for additional value-added services. Lead proposals for new engagements by preparing tender documents, presenting at client pitches, and crafting innovative solutions for client challenges. Actively participate in business development initiatives alongside Directors and Partners to identify new targets and grow the practice’s reach. Serve as a role model for organisational values by demonstrating integrity, collaboration, and commitment in all interactions.

To excel as a Senior Manager International Tax, you will bring proven experience advising multinational organisations or large corporates on intricate cross-border tax matters. Your background may include both advisory work and compliance; however, what sets you apart is your technical proficiency combined with an empathetic approach towards coaching others.
