Payroll Specialist / Admin
Full-Time | Direct Hire | On-Site | Miami Lakes, FL 33014
Client is a professional services firm providing payroll processing, fractional HR, business consulting, and retirement administration for growing businesses. We serve as a trusted back-office partner to our clients — helping them stay compliant, operate efficiently, and scale with confidence. Our team is hands-on, relationship-driven, and deeply committed to delivering reliable support to the businesses we serve.
Role Overview
Client is looking for a sharp, experienced Payroll Specialist / Admin to serve as a key right-hand resource to our team. In this role, you will be the primary point of contact for a portfolio of trusted clients, handling payroll review, compliance questions, and day-to-day support. You will not be processing payroll directly — our clients submit their own payroll runs — but you will be reviewing submissions for accuracy, flagging issues, and providing expert-level guidance on payroll rules, taxes, and compliance. This is a role for someone who knows payroll inside and out.

Log into client 401k and benefits reporting systems to enter and submit deduction amounts each payroll cycle
Ensure accurate calculation and handling of pre-tax vs. Roth (post-tax) contributions and deductions
Provide application and navigation support on ADP RUN — guiding clients on how to locate reports, make configuration changes, and resolve system questions
Handle client inquiries via phone and email on payroll processing, payroll taxes, deductions, garnishments, and compliance
Support bookkeeping and reconciliations in QuickBooks Online
Assist with HR administration, benefits administration, and client onboarding as needed
Maintain accurate, organized client records and documentation
