Payroll & Benefits Administrator

Job Description: We're looking for a Payroll & Benefits Administrator to keep semi-monthly payroll accurate and on time across Canada and the U.S. You'll own the day-to-day mechanics of the job - entering and verifying employee data in the HRIS and payroll systems, processing benefits and pension transactions, and staying compliant across multiple jurisdictions — plus the reporting, reconciliations, and year-end filings that keep the business audit-ready. You'll report to the Payroll & Benefits Manager, North America, and work closely with the Talent (HR) Manager, Talent Engagement Specialist, IT, and Finance.

• Coordinate and administer semi-monthly payroll for salaried and hourly employees across Canada and the U.S., ensuring accuracy and compliance with local laws
• Run pre-payroll reports for regular and off-cycle payrolls, and prepare termination documentation, for review by the Payroll & Benefits Lead
• Validate timesheets and hours worked, and run routine payroll reconciliations to catch missing hours or duplicate entries
• Prepare annual tax documents (T4s, W-2s, ROEs) and support year-end reporting, journal entries, and payroll tax reconciliation across both countries
• Process benefits and pension transactions — new enrollments, life event updates, terminations — and support pension contribution file uploads to providers
• Balance and reconcile benefit invoices for Canada and U.S. group plans, and maintain time-off accrual accuracy through routine audits and system syncs
• Maintain accurate, synced employee and compensation data across HRIS, payroll, and benefits systems, and generate regular headcount, cost, and leave reporting
• Respond to employee payroll and benefits inquiries promptly and professionally, escalating complex issues to the Payroll & Benefits Lead when needed
• Liaise with benefits providers on day-to-day requests — ID cards, coverage confirmations — and support wellness program communications and participation tracking
• Support new hire and open enrollment logistics, and partner with HR and Payroll/Benefits leadership on leave management, including maternity and medical leave
• Prepare responses to Unemployment Insurance requests and support workers' compensation reporting, filings, and audits in both Canada and the U.S.
• Flag process inefficiencies and gaps as you find them, and work with HR and Payroll/Benefits leadership to fix them
• Maintain strict confidentiality and data-privacy discipline as the person closest to sensitive payroll and benefits data
• Support audits and internal reviews by pulling accurate, well-organized data on request

Job Requirements:

• 3–5 years of hands-on payroll and benefits administration experience, ideally spanning both Canada and the U.S. (120 people, they want to double it in a year). lots of manual payroll
• Working knowledge of payroll legislation, tax compliance, and employment standards in Canadian and U.S. jurisdictions
• Experience with payroll/HRIS systems such as ADP or BambooHR, and full-cycle payroll processing (active thinker of how information flows)
• Experience administering benefits, wellness programs, and pension plans
• High attention to detail and strong reconciliation instincts — you catch the missing hour and the duplicate entry before anyone else does
• Discretion and professionalism handling sensitive payroll and employee data
• Strong Excel skills and comfort working across HR and payroll systems
• Ability to manage competing deadlines and stay composed under pressure
