The Role

AspenTech is the world's leading supplier of software that optimizes process manufacturing.

We have an exciting career opportunity for an experienced Senior Payroll Analyst to support accurate, timely, and compliant payroll operations across Latin America, with responsibility for Mexico, Brazil, Colombia, and Argentina. This role applies strong Mexico payroll expertise and broader LATAM payroll knowledge to independently manage assigned payroll activities, analyze and resolve moderately complex issues, and coordinate effectively with employees, HR, Finance, Treasury, payroll providers, and other partners.

The role works within established policies and broad guidelines, exercises judgment in day‑to‑day decisions, and escalates matters involving significant risk, policy interpretation, or exceptional complexity.

As a P3 / IC3 senior professional, this individual is expected to work with limited day‑to‑day instruction, solve moderately complex problems, contribute analytical insight, lead defined payroll projects or workstreams with limited risk and resource requirements, and serve as a knowledgeable resource to team members without formal people‑management accountability.
