- Design and oversee the end-to-end compliance ecosystem for business travelers, ensuring all international movements trigger appropriate visa, tax, and social security assessments.
- Act as the high-touch primary point of contact for senior leadership and complex assignees, managing their requests and minimizing risk.
- Drive the performance of external vendors (RMCs, Big 4 tax firms, immigration counsel), holding partners accountable to rigorous SLAs and KPIs.
- Oversee the mobility budget and global billing processes via Coupa, ensuring accurate cost allocation and identifying opportunities for cost-containment.
- Leverage mobility data to provide leadership with actionable insights on population trends, program ROI, and compliance heat maps.
- Identify and implement digital solutions to streamline the "travel-to-visa" workflow and improve the employee experience.

Your story

- Experience: 5+ years of dedicated experience in Global Mobility, International HR, or Tax/Immigration Consulting.
- Technical Knowledge: Deep understanding of social security treaties, double tax treaties and general knowledge on visa categories.
- Empathy: Exceptional communication skills; you can translate "legalese" into human language.
- Vendor Savvy: Experience managing external partners and holding them accountable to SLAs.

Meet the team

We are a hands-on Global Mobility team who believe that a strong foundation is built on knowledge, success is built on teamwork, and scale is achieved through automation and tech stack optimization. As a Global Mobility professional you should be as intuitive and forward-thinking as the people you support, finding ways to communicate complex topics effectively to guide business decisions and minimize risk for the individual team member and the organization. While we support the business as a function of our HR organization,, we don’t just "administer" programs and activate vendors, we build, customize, and innovate entirely in-house. Our mission is to deliver an excellent team member experience with knowledge, action, and a high degree of focus on the team member experience.

What we offer

On is a place that is centered around growth and progress. We offer an environment designed to give people the tools to develop holistically – to stay active, to learn, explore and innovate. Our distinctive approach combines a supportive, team-oriented atmosphere, with access to personal self-care for both physical and mental well-being, so each person is led by purpose.

On is an Equal Opportunity Employer. We are committed to creating a work environment that is fair and inclusive, where all decisions related to recruitment, advancement, and retention are free of discrimination
