Global Mobility Tax Manager

About the Role

OpenAI is building a scalable global mobility tax program that enables employees and the business to move quickly while managing tax compliance, risk, and employee experience. As Global Mobility Tax Manager, you will own the strategy and operating model for mobility tax across international and domestic business travel, assignment planning, cross-border moves, and other priority mobility scenarios.

This is a high-impact role for a builder who can translate complex tax requirements into clear policies, durable controls, and practical employee and business guidance. You will lead through expertise and influence across Payroll, Corporate Tax, Finance, Legal, People, business teams, and external advisors.

In this role, you will:

Set the global mobility tax framework, principles, governance, and service model in partnership with Corporate Tax teams.

Build clear policies and decision frameworks for international and domestic business travel, assignment planning, cross-border transfers, and other mobility scenarios.

Design the end-to-end operating model, including ownership, handoffs, controls, escalations, employee communications, and vendor responsibilities.

Partner with Payroll, Corporate Tax, Finance, Legal, People, and business leaders to identify tax implications early and support sound workforce decisions.

Establish reporting, dashboards, program health metrics, and issue-management routines that surface risk and drive timely remediation.

Automate high-volume workflows and use AI-enabled tools to improve case handling, documentation, data quality, and employee support.

Manage external tax advisors and vendor partners, service quality, and delivery against agreed standards, timelines, and outcomes.

Monitor regulatory and business changes, assess program impact, and continuously strengthen policies and controls.

You might thrive in this role if you:

Bring 8+ years of experience in global mobility tax, expatriate tax, business-traveler compliance, or a closely related field.

Have experience in both a leading tax advisory firm and an in-house global mobility tax function.

Have built or scaled mobility tax programs in a complex, fast-growing, multinational environment.

Bring knowledge of individual income tax, payroll withholding and reporting, social security, tax equalization or protection, and business-traveler compliance.

Can turn technical requirements into practical policies, controls, workflows, and clear guidance for employees and business partners.

Have a track record of leading complex cross-functional programs, influencing senior stakeholders, and driving decisions through ambiguity.

Use data, systems, and automation to improve compliance, visibility, efficiency, and service quality.

Have experience managing global vendors and implementing mobility tax technology.

Communicate with precision, exercise sound judgment, and balance employee experience with business and compliance needs.
