What You’ll Do

As we continue to expand our international operations and reach, we are seeking a highly experienced and detail-oriented Senior Payroll Specialist to join our payroll team, with a primary focus on our international payroll footprint across EMEA and APAC and an initial APAC focus on Singapore. The role reports to the Global Payroll Manager and owns day-to-day international payroll delivery, controls, issue resolution, and continuous improvement. This senior-level role requires deep expertise in end-to-end multi-country payroll processing, cross-border compliance, and systems management across ADP Celergo and other payroll platforms. The Senior Payroll Specialist will serve as a subject matter expert, support and mentor junior team members, and partner with HR, Finance, Legal, Stock Administration, and other stakeholders. Strategic direction, final payroll approval, material provider or compliance decisions, and significant risk acceptance remain with the Global Payroll Manager. This position is critical to ensuring accurate, compliant, timely, and well-controlled compensation for our workforce across Poland, Singapore, the United Kingdom, Norway, Spain, and Sweden, in line with each country's statutory pay cycle.

About the role

Payroll Processing & Systems Management

• Own the day-to-day end-to-end payroll process for employees across Poland, Singapore, the United Kingdom, Norway, Spain, and Sweden, partnering with in-country payroll providers and ADP Celergo and operating within the agreed governance and approval framework. Payroll scope includes base pay, commissions, bonuses, allowances, deductions, and other approved pay elements.
• Manage day-to-day relationships with ADP Celergo, assigned in-country payroll providers, and Employer of Record (EOR) providers; monitor delivery against agreed service levels; resolve operational issues; and elevate material service, compliance, contractual, or commercial concerns to the Global Payroll Manager.
• Maintain and monitor the international payroll calendar, including input deadlines, review dates, approval deadlines, funding dates, statutory payment dates, and year-end requirements.
• Prepare each payroll for approval, including a clear summary of material changes, exceptions, funding requirements, reconciliations, and identified risks, and obtain final approval from the Global Payroll Manager and other designated approvers before payroll or payment release.
• Operate in accordance with segregation-of-duties requirements so that no individual can independently prepare, approve, and release the same payroll or payment.
• Review and audit timesheets, attendance records, annual leave/PTO balances, and other country-specific inputs (e.g., UK statutory sick/maternity pay, Nordic parental leave, Spanish IRPF adjustments) to ensure accurate and compliant payment calculations prior to each payroll run.
• Coordinate and execute approved off-cycle payroll runs, retroactive pay adjustments, and manual payments across multiple countries and currencies, ensuring appropriate justification, review, approval, funding, and audit evidence.
• Oversee country-specific statutory deductions and employer obligations, including UK PAYE/National Insurance, Polish ZUS and PIT, Norwegian tax and folketrygd contributions, Spanish Seguridad Social and IRPF, Swedish tax and arbetsgivaravgifter, and Singapore CPF, in full compliance with applicable local laws.
• Coordinate payroll processing and reporting for RSU vesting, stock option exercises, and employee share purchase plan transactions for local and internationally mobile employees. Partner with Stock Administration, Legal, Global Mobility, and external tax advisers where cross-border tax treatment or specialist advice is required, and ensure timely payroll reporting and reconciliation.
• Support and monitor integrations and data flows between ADP Celergo, in-country payroll vendors, the general ledger, Workday HR, and benefits platforms, ensuring data integrity across multiple currencies, languages, and statutory calendars and escalating interface failures promptly.
• Manage payroll queries and escalations through the agreed case-management process, ensuring responses are accurate, appropriately documented, and delivered within established service-level expectations. Draft clear employee communications regarding payroll corrections, overpayments, underpayments, tax adjustments, and country-specific payroll matters, obtaining appropriate review for sensitive or material communications.

Compliance, Tax & Risk Management

• Maintain strong international payroll knowledge, with direct operational expertise in several of the covered countries and the ability to develop knowledge of additional jurisdictions through collaboration with in-country providers and specialist advisers. Proactively identify legislative or regulatory updates and coordinate required operational changes.
• Manage day-to-day multi-country payroll tax compliance activities across EMEA and APAC, including registrations, statutory filings, payment requirements, and routine correspondence with tax and social security authorities such as HMRC, ZUS and the Polish Tax Office, Skatteetaten, the Agencia Tributaria and Seguridad Social, Skatteverket, and Singapore's IRAS/CPF Board. Escalate material assessments, disputes, penalties, or compliance risks to the Global Payroll Manager.
• Support the Global Payroll Manager, Legal, Finance, Tax, and HR with new-country payroll assessments, registrations, implementation activities, documentation, testing, and operational readiness. Legal, tax, permanent-establishment, and employment-law determinations must be validated by the appropriate internal or external specialists.
• Review and reconcile statutory in-year and year-end payroll filings for each covered country (e.g., UK P60/P11D, Polish PIT-11, Swedish arbetsgivardeklaration, Norwegian a-melding, Spanish Modelo 111/190, and Singapore IR8A/IR21), prepare them for authorised approval, and partner with local tax representatives to resolve routine agency notices.
• Support the design, implementation, and ongoing operation of robust payroll controls to safeguard payroll data, comply with GDPR and local data-privacy requirements, and mitigate the risk of errors, fraud, or unauthorised access.
• Maintain complete payroll control evidence, approval records, reconciliations, issue logs, and audit trails for every payroll cycle in accordance with company record-retention requirements.
• Complete periodic payroll system and provider access reviews, bank-detail change controls, variance analysis, and post-payroll reconciliations, escalating control failures, suspected fraud, or unauthorised activity immediately.
• Coordinate day-to-day statutory and external audit activities related to international payroll, including preparation and management of payroll PBC (Prepared by Client) lists across jurisdictions, and elevate material findings or commitments to the Global Payroll Manager.
• Address and resolve payroll discrepancies, tax issues, and employee escalations across multiple time zones with urgency, accuracy, and professionalism.
• Partner closely with the Payroll Accountant and Finance team on payroll journal entries, multi-currency general ledger reconciliations, flux analysis, and accruals on a monthly, quarterly, and annual basis.

Process Improvement, Training & Leadership

• Champion continuous improvement by identifying, designing, and implementing process enhancements, automation opportunities, and best practices to increase efficiency, accuracy, and scalability across a growing international payroll footprint.
• Support the implementation and continued optimisation of ADP Celergo, including requirements gathering, data validation, configuration review, interface testing, user acceptance testing, parallel payroll testing, defect management, go-live readiness, change management, and post-go-live stabilisation. Overall programme ownership and material design decisions remain with the Global Payroll Manager and designated project governance.
• Create, document, and maintain comprehensive country-specific payroll process manuals, SOPs, control documentation, key-contact lists, access instructions, contingency procedures, and training materials to ensure business continuity and knowledge transfer.
• Provide effective payroll cover across assigned countries and participate in cross-training to reduce dependency on individual team members or external providers during planned or unexpected absences.
• Provide functional guidance, coaching, and training to junior payroll team members on multi-country payroll practices, fostering a culture of accuracy, compliance, accountability, and professional development. This responsibility does not include formal people management unless separately assigned.
• Manage assigned operational relationships with in-country payroll and benefits vendors, monitor performance against SLAs and agreed controls, and provide evidence-based recommendations to the Global Payroll Manager regarding service improvements or escalation.
• Collaborate with HR, Legal, Benefits, and works councils or employee representative bodies where applicable to effectively communicate and resolve payroll-related matters across regions in a professional and timely manner.
