Senior Tax Product Specialist

Job Description:

Corporate tax teams are being asked to do more, faster, and under greater scrutiny than ever—and AI is about to change how the work gets done. Are you a tax professional who wants to decide what that change looks like? As Senior Tax Product Specialist on the ONESOURCE Direct Tax team, you will be the practitioner at the table where our products are designed, built, and tested—making sure what we ship works the way corporate tax departments actually work. (Note: The equivalent industry role is typically a Tax Manager or Tax Director)
You will partner with product, engineering, and data science teams, and with enterprise customers and partners, to shape product content, functionality, and AI-powered capabilities across the corporate income tax lifecycle—from provision and compliance to planning and controversy. Your tax and accounting background is not incidental to this role; it is the foundation. You will bring the judgment of someone who has closed the books, filed the returns, and answered the auditor's questions, and you will use it to make our products accurate, intuitive, and trusted.
This role also carries a mandate to advance AI across ONESOURCE Direct Tax solutions. You will develop, test, and validate how agentic AI and intelligent automation apply to corporate tax workflows, give engineering and data science teams candid, practitioner-grounded feedback, and help define what responsible, high-quality AI looks like in a regulated tax environment.
Key Responsibilities:

Product Roadmap Delivery & AI

Shape and validate product content and functionality across ONESOURCE Direct Tax solutions, drawing on firsthand experience with how corporate tax departments handle provision, compliance, planning, and reporting.
Apply deep knowledge of corporate income tax—including ASC 740 and federal and state compliance—to assess product capabilities and surface high-impact improvement opportunities.
Develop, test, and validate agentic AI and intelligent automation across the direct tax lifecycle, including document understanding, data mapping and reconciliation, anomaly detection, and AI-assisted review.
Give engineers and data scientists direct, practitioner-grounded feedback on AI feature accuracy, performance, and real-world fit, using independent judgment built on tax experience.
Lead the development of advanced use cases for tax professionals using ONESOURCE and the broader Thomson Reuters AI portfolio, and build thought leadership in how AI applies to corporate tax practice.
Partner with product managers to bring domain expertise to roadmap prioritization, requirement definition, and feature validation, so what gets built reflects how corporate tax work is actually done.
Create guidance, use case documentation, and adoption resources that help tax
