This 12-month fixed-term assignment offers a unique opportunity to contribute to both the day-to-day intricacies of payroll processing and the strategic advancement of global payroll transformation initiatives.
  • • You will be entrusted with the end-to-end management of payroll for assigned European countries, working in close collaboration with our trusted external payroll vendors, such as ADP and Safeguard. This involves overseeing all stages of the payroll cycle, from data input and validation to final processing and distribution.

This includes scrutinizing gross-to-net reports to identify any discrepancies, conducting variance checks to ensure financial accuracy, and verifying payment files and statutory submissions to guarantee compliance with all local regulations.

  • • To foster operational efficiency and knowledge sharing, you will be responsible for maintaining up-to-date payroll documentation, detailed workflows, and clear process guidelines. This ensures consistency and facilitates smooth operations, especially during periods of change.
  • • You will serve as a key point of contact, providing essential support and guidance to employees, HR teams, managers, and external stakeholders on a wide range of payroll-related queries and issues.
  • • Proactive risk management is essential. You will be expected to identify, escalate, and support the resolution of any risks, issues, or data inconsistencies that may arise during the payroll process, ensuring minimal disruption and maintaining compliance.
  • • As Avantor continues to evolve its payroll processes and systems, you will contribute significantly to training and communication efforts. This involves educating stakeholders and ensuring a smooth transition during any process or system enhancements.
  • • This role is fully remote, offering flexibility and the opportunity to work from Ireland. You will be an integral part of our Global Payroll team, contributing to our mission of delivering exceptional payroll services worldwide.
  • • By joining Avantor, you become part of a global team of 14,000+ associates dedicated to advancing life-changing science.
