📐 About the role
We're looking for a hands-on, detail-obsessed global payroll manager to join our team. This is a high-ownership individual contributor role that sits at the intersection of finance and human resources.
You will own end-to-end payroll for a multi-entity, multi-currency, multi-regulatory environment spanning the US, UK, Canada, Singapore, the UAE, and a growing set of Employer of Record (EOR) countries across Europe. You'll also manage contractor payroll and oversee 401(k) and pension administration.
This is a role for someone who is energized by complexity — who sees a fragmented global payroll landscape and wants to bring order, accuracy, and scale to it.
🦸🏻♀️ What you’ll do
End-to-end payroll execution across all of WRITER’s active entities and pay schedules, including multi-state US payroll with varying pay frequencies, and commission cycles; UK PAYE with HMRC filings, National Insurance contributions, pension auto-enrolment, and statutory pay calculations; Canadian federal and provincial remittances, Record of Employment filings, and CPP/EI; Singapore CPF contributions, MOM compliance, and IR8A filings; UAE WPS compliance and gratuity calculations; and contractor payroll with IC agreements, payment schedules, and 1099-equivalent filings.
You will coordinate with each EOR provider, validate invoices against actuals, and resolve discrepancies — turning a high-volume, distributed model into an auditable workflow.
You own the processing of the payments, and support the finance team’s general ledger journals, month-end reconciliations, and variance analysis.
You will work closely with the finance team to ensure payroll liabilities, accruals, and actual disbursements are reflected accurately across entities.
You will manage cycle-by-cycle processing for variable compensation, working directly with Finance and Revenue Operations to ensure timing, accuracy, and correct tax withholding
You will stay ahead of — not just keep up with — evolving payroll tax requirements across every jurisdiction WRITER operates in.
You will manage W-2s, P60s, P45s, T4s, and other international equivalents, and ensure our regulatory filings are complete, accurate, and on time across monthly, quarterly and annual cycles.
You will reconcile benefits deductions against carrier invoices and manage international statutory leave top-up calculations across jurisdictions with varying leave frameworks.
As Writer expands, you will lead new country setup for Payroll operations: systems configuration, testing, and end to end cycle execution.
You will be a trusted resource for employees navigating payroll questions, tax situations, payslip discrepancies, and equity withholding — especially during peak seasons like tax filing and open enrollment.
You will identify manual inefficiencies and build scalable workflows that integrate cleanly with Finance and HR systems.
⭐️ What you need
6–10+ years of payroll experience, ideally in a high-growth, global technology company
Experience with Rippling Payroll
Strong command of US multi-state payroll — multi-frequency schedules, state-specific compliance
International payroll experience across at least two of: UK, Canada, Singapore, or UAE
Experience managing EOR and third-party payroll vendors — coordinating across providers, reviewing outputs for accuracy, and holding vendors to a high standard
Regulatory expertise and compliance instincts — you research evolving requirements proactively, not reactively
Systems proficiency, and aptitude for learning new tools quickly
Analytical rigor and documentation habits — high accuracy, strong attention to detail, and a paper trail you'd be comfortable showing an auditor
Clear, effective communication — able to partner with Finance, Legal, and People teams, and equally able to explain a payroll discrepancy to an employee who just wants to understand their payslip
Proactive, systems-minded approach — you spot inefficiencies before they become problems, and you're energized by building better processes
Even better if…
Familiarity with equity compensation tax and withholding (RSUs, options)
Experience supporting global entity setup and new-country payroll launches
CPP (Certified Payroll Professional) or equivalent certification
Experience designing or managing scalable payroll audits and internal controls
Background working with shadow payrolls or complex expatriate payroll arrangements
Payroll accounting fundamentals — you are comfortable with GL journals, month-end reconciliations, and can speak the language of Accounting
🍩 Benefits & perks (US Full-time employees)
Generous PTO, plus company holidays
Medical, dental, and vision coverage for you and your family
Paid parental leave for all parents (16 weeks)
Fertility and family planning support
Early-detection cancer testing through Galleri
Flexible spending account and dependent FSA options
Health savings account for eligible plans with company contribution
Annual work-life stipends for:
Wellness stipend for gym, massage/chiropractor, personal training, etc.
Learning and development stipend
Company-wide off-sites and team off-sites
Competitive compensation, company stock options and 401k
