Thomson Reuters US | Senior Tax Product Specialist

Responsibilities

• 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.
• This role also carries a mandate to advance AI across ONESOURCE Direct Tax solutions.
• Our benefit package includes market competitive health, dental, vision, disability, and life insurance programs, as well as a competitive 401k plan with company match.
• 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.
• 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.
• 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 professionals get value from new capabilities quickly.
• Engage directly with enterprise customers—including corporate tax directors, controllers, tax managers, and Big Four advisors—as a credible peer who understands their workflows, pressures, and standards.
• Partner with Customer Success, Sales, and Support to drive adoption, resolve complex tax questions, and strengthen customer satisfaction and retention.
• Collaborate with UX/design, engineering, compliance, and go-to-market teams as the authoritative internal voice of the corporate tax professional throughout the product lifecycle.
• Coordinate with other Thomson Reuters divisions and teams on initiatives where direct tax expertise and cross-product alignment are needed.
• Translate what you hear from practitioners into clear, actionable input for the product team, serving as the ongoing bridge between real-world tax practice and product development.
• Making a Real-World Impact: We are one of the few companies globally that helps its customers pursue justice, truth, and transparency.

Requirements

• Minimum 5–7 years of professional experience in corporate tax or public accounting environment, with hands-on responsibility for corporate income tax provision, compliance, or planning.
• Deep, working knowledge of corporate direct tax processes is required, with demonstrated depth in at least one core area: income tax provision, compliance, or planning.
• Demonstrated ability to apply tax best practices to assess software functionality, identify gaps, and articulate what a high-quality direct tax solution should do.
• Prior use of enterprise corporate tax software—such as ONESOURCE, Checkpoint, Corptax, Longview, etc.—is strongly preferred; direct ONESOURCE experience is a significant plus.
• Proven experience working with or evaluating AI tools in a professional context, with the ability to assess accuracy, reliability, and fitness for use in high-stakes tax workflows.
• Comfortable collaborating with engineering and data science teams to test AI-powered features and provide practitioner-grounded feedback.
• Strong written and verbal communication skills, with the ability to translate complex tax concepts into clear product guidance, customer-facing materials, and cross-functional requirements.
• Experience drafting guidance documents, use case materials, or training content for professional audiences.
• Proven ability to work effectively across internal teams — product, engineering, sales, and customer success — in a fast-paced, collaborative environment.
• Prior experience in a product specialist, solutions consultant, or subject matter expert role within a tax or financial technology company.
• Experience at a Big Four or large regional accounting firm, or within the tax function of a large multinational corporation.
• Hands-on experience testing, validating, or providing feedback on AI-powered features in enterprise software.
• Familiarity with ERP platforms relevant to tax data (SAP, Oracle, Workday, NetSuite).
• Experience presenting to or engaging with executive stakeholders in an advisory, SME, or thought leadership capacity.
• This role is a rare opportunity for an experienced tax professional to move from using the tools to shaping them—and to help ensure that software elevates tax professionals to do their highest-value work.
