Job description

You’ll provide day-to-day operational support to the Human Resources Manager and Accounting Manager. A significant portion of your time will be dedicated to reviewing weekly and biweekly timesheets, identifying missing or inaccurate entries, monitoring overtime and baseline-hour discrepancies, and preparing accurate payroll information across weekly, biweekly, and semimonthly payroll schedules.

You’ll support payroll processing in ADP by maintaining new-hire and employee data; reviewing local tax jurisdictions, first-pay timing, home departments, direct deposits, compensation and profile changes, bonuses, terminations, deductions, arrears, allowances, expense reimbursements, and other payroll-impacting items. You’ll also prepare payroll change files, HSA and FSA uploads and funding, general-ledger files, quarterly balancing and tax documentation, benefit invoices, year-end W-2, 1095-C, and 1099 preparation, and organized payroll records in OneDrive.

Within Human Resources, you’ll coordinate onboarding administration, request IT and systems access, build complete and accurate employment profiles, monitor Form I-9 completion and reverification, and provide benefits administrative support by processing enrollment and coverage changes with medical and other benefit carriers. You’ll maintain confidential employee records, follow up on missing information, respond to routine employee questions, and assist with additional HR administrative and compliance projects.

You’ll be successful if you are able to:

• Review weekly and biweekly timesheets and resolve missing or inaccurate entries, overtime, PTO, coding, and baseline-hour issues before payroll.
• Prepare weekly, biweekly, and semimonthly payroll files, reports, uploads, funding requests, and reconciliations accurately and on time.
• Maintain complete ADP data for new hires, employee changes, tax jurisdictions, direct deposit, deductions, bonuses, allowances, and terminations.
• Complete onboarding access requests and employment-profile setup in time for each employee’s start date and first payroll.
• Maintain complete Form I-9 records and monitor required reverification dates.
• Process benefit enrollment and coverage changes and confirm carrier records align with payroll deductions.
• Track payroll follow-up items, arrears, quarter-end and year-end tasks through completion while protecting confidential information and escalating material concerns.

Collaborating With

You will work closely with employees, department leaders, managers, IT, ADP, benefit carriers, and members of the Accounting and Human Resources functions. Strong coordination across these groups is essential to keeping employee information, benefits, timekeeping, and payroll activity accurate and timely.

Who You Are

• Detail Guardian: You catch discrepancies others may miss and understand that small errors in employee data, timekeeping, taxes, or deductions can have a meaningful impact.
• Payroll Problem Solver: You research exceptions, compare information across systems, and follow an issue through until the underlying cause is understood and corrected.
• Deadline Driver: You manage recurring weekly, biweekly, monthly, quarterly, and annual requirements without losing sight of changing priorities.
• Trusted Steward: You handle employee, payroll, benefit, and financial information with discretion, sound judgment, and consistent confidentiality.
• Process Coordinator: You keep checklists, records, files, approvals, and follow-up items organized so every step is completed and documented.
• Collaborative Partner: You communicate professionally with employees, managers, vendors, and leaders and know when to resolve an issue independently or elevate it.

What You Need

• Two or more years of experience in payroll, Human Resources administration, benefits administration, accounting support, or a closely related role.
• Hands-on ADP experience is strongly preferred; ADP Workforce Now experience is especially valuable.
• Experience reviewing timesheets and working with payroll deductions, tax setup, direct deposit, PTO, overtime, reimbursements, and employee changes.
• Working knowledge of onboarding administration, Form I-9 requirements, employee records, and benefit enrollment or carrier changes.
• Intermediate proficiency with Microsoft Excel and comfort working in Word, Outlook, OneDrive, and web-based business systems.
• An associate degree in Human Resources, Accounting, Business Administration, Finance, or a related field is preferred; equivalent relevant experience will be considered.
• Multi-state or multi-jurisdiction payroll experience and familiarity with payroll or benefit reconciliations are preferred.
• Strong accuracy, organization, follow-through, communication, and the ability to manage confidential information and recurring deadlines.
