Description
About MARI Group
MARI is a global events and experiences company powering world-defining live experiences. Our portfolio of premium live properties spans sports, art, and entertainment — including the Madrid and Miami Open tennis tournaments, Frieze (a leading voice in contemporary art), and Barrett-Jackson (the premium U.S. collector car auction company). MARI also includes TodayTix Group, the global e-commerce leader for cultural experiences, connecting millions of customers with the best in live entertainment.
MARI is reshaping the live events landscape — building a growing portfolio of category-defining events and brands that set the standard for what's next, across sports, entertainment, art, and lifestyle.
At MARI, you'll work alongside people who are passionate, curious, and driven — people who believe that live experiences have the power to shape culture, and who care about the work, the mission, and each other. We welcome outstanding applicants of all backgrounds and encourage everyone to apply.
About the Role
The global HR Operations team plays a critical role in delivering an exceptional and consistent employment experience at MARI. As an HR Operations Coordinator, you’ll be part of a small but growing global HR team, reporting directly to the VP, HR Operations, and working closely with HR Business Partners, Payroll, Finance, IT, and Facilities.
MARI is a highly acquisitive company in an exciting phase of growth, and this role offers a unique opportunity to join a developing team and grow alongside the business. Sitting at the heart of the HR function, this is a broad and varied role that provides hands-on ownership of core HR operations while offering meaningful exposure to HR business partnering and M&A integration work.
You’ll provide dedicated HR transactional support across the employee lifecycle for our diverse employee populations, ensuring accuracy, timeliness, and a positive employee experience at every stage. We’re looking for someone who is highly detail-oriented, able to prioritize and manage deadlines, and who thrives in a lean, fast-moving, build‑it‑as‑you‑go environment where processes are evolving and impact is tangible.
This is a full-time role and qualified candidates must be based in the greater London area. You'll be part of a hybrid team that values both connection and flexibility. We'll cover the details of our hybrid schedule during the interview process.
