Senior Tax Product Specialist

The Senior Tax Product Specialist is an individual contributor role at the heart of the ONESOURCE Tax Provision product team.

This role also carries a specific mandate to advance AI initiatives within ONESOURCE Tax Provision. You will develop, test, and validate the application of generative AI and intelligent automation to corporate tax workflows - providing strategic feedback to engineering and data science teams and helping define what responsible, high-quality AI looks like in a regulated tax environment.
