Payroll Officer (junior) – Regio Diegem/Zaventem | Pro-Pay

Do employment law, social legislation and payroll genuinely interest you?

At Pro-Pay, we help international employers manage Belgian payroll and employment obligations. As a Junior Payroll Officer, you'll develop expertise in payroll calculations, social security legislation and employment law while supporting employers with employees in Belgium.

This is not a purely administrative role. It is a specialist profession where accuracy, analytical thinking and a passion for legislation are essential.

Your role as Payroll Officer (junior)

You manage your own client portfolio of international employers with employees working in Belgium. Every payroll file is different and requires a good understanding of Belgian social security legislation, employment law and payroll regulations.

If you enjoy solving complex questions and strive to become an expert in your field, you'll fit right in.

Your responsibilities include:

• Supporting the monthly payroll run and assisting with calculating, analysing and reviewing payslips, ensuring employees are paid correctly and on time.
• Processing administrative employee data for our clients and assisting with Dimona declarations, DmfA filings and payroll reporting.
• Learning how to apply Belgian social legislation in payroll cases and developing your socio‑legal knowledge further.
• Handling first‑line payroll questions from clients and building strong, professional client relationships.
• Working closely with colleagues in a multicultural team and taking initiative when you see opportunities to improve processes.

Who are we looking for?

You’re a perfect match for this role if you:

• have a first experience in payroll administration (e.g. internship, student job or an initial role within a social secretariat);
• have deep affinity for social legislation, and want to understand payroll calculations from A to Z;
• are trilingual (ENG – NL – FR) or motivated to grow towards it (English C1 is required);
• have strong analytical skills and enjoy working with numbers, client contact and flawless administration;
• enjoy collaborating in a warm team where learning and knowledge‑sharing are part of daily life;
• get energy from delivering high‑quality service and take a proactive approach with clients;
• are a true team player who works hard but also enjoys having fun;
• feel an extra boost of focus and motivation during peak periods and deadlines.

What we offer you

• A permanent contract with a competitive salary tailored to your growth potential.
• A company car with charging card or a mobility budget.
• A comprehensive benefits package: meal vouchers, eco vouchers, hospitalisation insurance, group insurance, net expense allowance and access to our discounts platform.
• Healthy work‑life balance through hybrid working, flexible hours and a flexible schedule including 12 ADV extra leave days.
• Clear growth opportunities towards deeper expertise, with increasing responsibilities, larger client portfolios and more complex payroll cases.
• A multicultural, warm and people‑focused work environment where teamwork is central and personal growth is truly supported.
• Regular team events and teambuilding activities, helping you feel connected, valued and at home within the team.
