Katarzyna Sacharuk

I’m an HR & Payroll Specialist with 12+ years of experience supporting end-to-end employee lifecycle, payroll operations, and HR compliance in local and international environments. I act as an in-country HR partner for Poland within global organizations, supporting international clients operating in Poland without local entities (EOR-like model).

I advise stakeholders on Polish labor law, manage complex HR case/ticketing workflows, and coordinate with external payroll providers to ensure compliant and accurate payroll delivery. In Shared Services settings, I prepared and validated monthly payroll inputs (Hire-to-Retire), handled onboarding/offboarding and contract changes, and ensured GDPR and broader compliance across HR documentation.

I’m recognized for accuracy, ownership, and process optimization—especially improving employee experience and operational excellence. I’ve independently built and managed a fully operational Polish HR desk in a global Shared Services model, reduced HR documentation turnaround time by 25%, and maintained high payroll data accuracy across multi-country environments while partnering closely with vendors, finance, and auditors.
