What if your tax expertise could do more than manage compliance — what if it could help change patients' lives? It might not be the first thing that comes to mind when you think about a tax role but at Bristol Myers Squibb, everything connects back to our purpose: transforming patients’ lives through science. And the team that keeps our tax operations running with precision and integrity?

They're part of that story too. We're looking for a Senior Tax Manager to join our European Tax Centre of Excellence (COE) in Chester - a role where your technical skills meet real business influence and where the work you do every day genuinely matters. This is a tax role with real breadth. And real accountability for the outcomes across your markets.

Here’s what makes this different from a standard in‑house tax position: you won't be a cog in a machine, processing the same returns year after year. You'll lead a portfolio of European markets and direct a team of tax professionals - working closely with local finance teams and external advisers to high‑quality processes. You'll be the expert your finance colleagues come to when they need clarity, the professional who challenges external advisers on both direct tax and VAT matters, the senior lead who manages tax audits through to resolution, and the person who translates complex legislation into practical action to guide our stakeholders.

You’ll run the full direct tax cycle for your own markets - leading corporate income tax return preparation with local external advisers, applying genuine technical challenge to their work, managing tax authority audits and enquiries through to resolution, drawing on your working knowledge of VAT where indirect tax questions arise, and making sure nothing falls through the cracks.

You’ll gain hands‑on US GAAP experience - preparing and submitting US tax reporting including quarterly current and deferred tax provisions using Tax Stream technology. This isn't something most in‑house European tax roles offer, and it's a genuine differentiator for your CV.

You’ll work across the full breadth of tax governance - staying on top of evolving regulatory requirements across your markets, including the evolving world of Pillar Two. You’ll be a genuine internal consultant - advising finance and business stakeholders on tax matters, explaining complex technical requirements in language they can act on, and building the kind of trusted relationships that make you indispensable.

You’ll coach and assist in developing a team of tax professionals - setting objectives, coaching technical development, and building a team that delivers to a consistently high standard across your markets.

You’ll shape how tax is done, not…
