Senior Payroll Analyst

Skills

About the Role

You will own multi-jurisdiction payroll execution across 34 US states and Canada, drive continuous process improvements, and serve as a key partner to HR, Finance, and Legal as we scale. This role collaborates closely with People Operations and Accounting. If you’re based within a pre-determined commuting distance of one of our offices (SF, NY, London, or Berlin), the role includes in-office anchor days on Monday, Tuesday, and Friday. If you're located beyond that distance, the role is fully remote. For location-specific details, please connect with our recruiting team.

Requirements

• 4 - 7 years of payroll experience, with at least 3 years handling multi-state US payroll at scale (1,000+ employees).
• Hands-on proficiency with ADP Workforce Now (WFN); you know it deeply, not just surface-level.
• Experience with Workday as an HRIS, including integration data flows between Workday and a payroll processor.
• Demonstrated experience processing Canadian payroll, including provincial compliance and year-end requirements.
• A track record of owning and shipping process automations and improvements. Strong grasp of US payroll tax concepts: federal withholding, FICA, SUI/SIT, imputed income, supplemental wages, and equity-related taxation (RSUs, NSOs, ISOs).
• Meticulous attention to detail paired with the ability to prioritize in a fast-moving environment.
• Excellent cross-functional communication skills; comfortable explaining payroll nuance to non-payroll audiences.
• Exposure to pre-IPO or high-growth tech environments.

Responsibilities

• Process full-cycle, multi-state US payroll end-to-end across bi-weekly and semi-monthly pay cycles using ADP Workforce Now and Workday.
• Work with third party providers to process Canada and LATAM payrolls.
• Reconcile payroll data between Workday HRIS and ADP WFN, ensuring accuracy of earnings, deductions, taxes, and benefits contributions before each pay run.
• Manage multi-state tax compliance across all 34 active states including new-hire reporting, SUI/SIT registration, local tax setup, and year-end W-2/T4 processing.
• Administer Canadian payroll in compliance with federal and provincial requirements (source deductions, ROEs, T4s, and year-end remittances).
• Partner with HR, Total Rewards, and Finance to process payroll changes including new hires, terminations, LOAs, equity compensation events, and off-cycle payments.
• Identify, document, and lead process improvement initiatives that increase accuracy, reduce manual effort, and scale with company growth - you’ll be expected to leave each process better than you found it.
• Support payroll audits, internal controls reviews, and SOX-adjacent compliance activities as the company moves toward an IPO-ready finance posture.
• Serve as a tier-2 escalation point for employee payroll inquiries, resolving issues with speed and professionalism.
• Monitor regulatory changes in federal, state/provincial, and local tax law and proactively flag impacts to the team.
• Contribute to the buildout of payroll infrastructure to support international expansion beyond the US and Canada.

Benefits

• Competitive compensation package, including equity.
• Inclusive Healthcare Package.
• Learn and Grow - we provide mentorship and send you to events that help you build your network and skills.
• Flexible Time Off.
• We will provide you the gear you need to do your role, and a WFH budget for you to outfit your space as needed.
