International Payroll Specialist

Competitive + Bonus

Glasgow, UK

12 month FTC

At IRIS FMP International, part of the IRIS Software Group, we help businesses pay their people across the world - accurately, on time, and in full compliance with local laws.

Our International Operations team manages payroll delivery in multiple countries, working closely with clients and in-country payroll partners to make sure everything runs exactly as it should. We’re organised, precise, and great at building strong, long-term relationships.

We’re now looking for a Senior International Client Payroll Executive to join us on a fixed-term contract until January 2027, covering maternity leave.

What the Team Does

Our team sits at the heart of international payroll delivery for IRIS.

We connect clients with our network of in-country partners - coordinating data, managing timelines, and ensuring every step of the process happens on schedule.

Each Advisor looks after a small group of key clients (typically 5-10) covering 10–15 country payrolls across the UK and continental Europe. It’s a role that blends structure, service, and partnership - giving you the chance to build trusted professional relationships (and often genuine friendships) with the clients who rely on you.

What Will You Be Doing?

• Manage the end-to-end payroll process for your portfolio of international clients


• Coordinate the flow of data between clients and payroll partners, ensuring accuracy and timeliness


• Act as the main client contact - answering questions, resolving issues, and keeping everyone informed


• Track key deadlines and make sure every payroll cycle stays on schedule


• Support audits and maintain accurate documentation for compliance


• Monitor KPIs / SLAs and report performance clearly


• Review and improve internal processes to make life easier for clients and colleagues


• Check in regularly with clients to plan ahead and strengthen relationships

This is a well-structured, stable role - typically busier towards month-end, with quieter periods at the start of each month for client check-ins and forward planning.

What Are We Looking For?

• Excellent customer service and relationship-building skills - you’ll be the trusted point of contact for some of our largest global clients


• Confident managing multiple deadlines and stakeholders across different time zones


• Highly organised with strong attention to detail


• Proactive, calm under pressure, and able to prioritise effectively


• Fluent in English; an additional European language such as French, Spanish, or Italian would be a real plus


• Confident using Microsoft Excel and Office 365


• Previous experience in a client-facing payroll, operations, or service environment


• Experience working with international or multi-country payrolls would be advantageous, especially if you’ve coordinated between clients and in-country partners to deliver accurate, compliant results

What Can IRIS Offer You?

• The opportunity to manage global client relationships and oversee payrolls across multiple countries


• A supportive, friendly, and collaborative team culture


• Clear structure and stability - predictable monthly cycles and long-term client partnerships


• Remote working anywhere in the UK


• Professional development within a respected global payroll brand


• The satisfaction of helping businesses pay their people correctly, every time
