Introduction

Optimizely Tax is seeking a technically strong and forward-thinking US Tax Manager - Federal & SALT to own our US income tax function. Reporting to the Global Head of Tax, you will lead US federal and state & local tax compliance and provision – both of which are delivered through external advisors – with full responsibility for quality, timeliness, and strategic oversight. You will act as Optimizely's primary internal US tax authority, partnering closely with Finance, Legal, and business leaders. 

This is also an AI-enabled process transformation role. Optimizely equips its Tax team with a market-leading suite of AI tools and trusted tax knowledge platforms, including: Opal (Optimizely's own internal AI platform), Claude Cowork Enterprise, Bloomberg Tax AI, and Loctax (connected to IBFD, providing deep cross-border and international tax intelligence). We will invest in developing your capability across these tools and expect you to become an increasingly confident user and advocate, using them to drive research quality, reduce manual effort, and unlock capacity for higher-value, more rewarding work. 

Why you will enjoy this role:

You'll have unusual autonomy for a `-level tax role. Rather than preparing returns yourself, you'll direct external advisors, shape tax strategy, modernise processes using AI, and work closely with senior Finance leadership and the business on high-impact projects.  

You'll be joining a tax function that actively invests in technology, equipping you with the tools and the support to simplify and automate routine work, modernise the way tax is delivered, and ensure your expertise can be focused where it adds the greatest value. 

As Optimizely continues to grow, you'll have the opportunity to broaden your technical expertise, increase your strategic influence, and help shape the future direction of the global tax function.
