HR & Payroll - Associate

This is a newly created hybrid role sitting across Pantheon’s HR and Payroll functions in New York. It brings together two priorities for the North America platform: reliable, accurate delivery of US payroll and Benefits/401(k) administration, and day-to-day HR support for the region with dedicated, Spanish-language support for the Colombia office.

The Associate will spend the majority of their time on Americas payroll processing and benefits and retirement plan administration, and the remainder supporting the North America employee lifecycle and HR operations and provide support to the UK based payroll team. It suits someone who is numerate, detail-focused, discreet with confidential data, and comfortable working across two functions and multiple jurisdictions. Fluency in Spanish is essential.
