Zilliant is a SaaS company on a mission to eliminate Pricing Anxiety and turn pricing into a strategic advantage for our customers. Guided by our values—People First, Trust, Accountability, Impact, and Innovation—we deliver intelligent solutions that align teams, build confidence, and drive sustainable growth. We know our business is about more than just software—it’s about the people who power it, from our dedicated team to the customers we serve.

Zilliant is looking for a detail-oriented People Operations Specialist with a strong focus on payroll to join our HR team. In this role, you will serve as a key owner of global payroll operations while also supporting core People processes across the employee lifecycle. You’ll ensure accurate and compliant payroll delivery across multiple countries, while contributing to a seamless and high-quality employee experience. You’ll work closely with HR, Finance, and external payroll providers.

What You’ll Do:

Own end-to-end payroll processing across the U.S. and international regions (ADP Workforce Now, ADP Celergo, OysterHR), including salary changes, bonuses, commissions, and terminations on a monthly and semi-monthly cadence
Review and audit payroll data for accuracy and compliance, including severance, sign-on bonuses, retention bonuses, referral bonuses, and merit increases
Manage ongoing payroll-related audits and processes including 401(k) contributions (weekly), UK pension updates and submissions (monthly), termination reporting, SOC, and benefits-related payroll changes
Support global payroll cycles including variable/bonus payouts, year-end processing, ACA reporting, EEO-1 reporting, and distribution of tax documents across all countries
Maintain and update employee records in HR systems, ensuring accuracy across payroll, benefits, and personnel data
Support the employee and contractor lifecycle from onboarding through offboarding, including new hire paperwork, E-i9, system updates, and employee communications
Partner cross-functionally with HR, Finance, and external vendors to resolve payroll issues, improve processes, and ensure compliance with local regulations

What You Won’t Do:

Perform transactional payroll processing without ownership - you’ll be accountable for accuracy, compliance, and continuous improvement
Work in isolation - you’ll collaborate regularly with HR, Finance, and external partners

Who You Are:

Highly detail-oriented with a strong commitment to accuracy, compliance, and data integrity
Organized and able to manage multiple payroll cycles, deadlines, and global requirements simultaneously
A proactive problem-solver who identifies discrepancies and drives resolution
A strong communicator who can partner effectively with cross-functional stakeholders and external vendors
Process-minded and always looking for ways to improve efficiency and scalability

What You’ll Need:

3+ years of People Operations or payroll experience, with strong hands-on payroll ownership
Experience with ADP Workforce Now required; experience with ADP Celergo, OysterHR, or similar global payroll platforms strongly preferred
Knowledge of U.S. payroll regulations and familiarity with international payroll practices
Experience auditing payroll data, benefits, and tax-related documentation
Experience supporting broader HR processes such as onboarding, employee data management, and benefits administration
Strong Excel skills and analytical mindset

What You’ll Enjoy:

Full benefits package including medical, dental, and 401k plans with a company match
Generous Paid Time Off (PTO) policy to ensure a solid work/life balance
Monthly Zilliant Zen Days to rest and recharge
Comprehensive parental leave to provide time to bond with new family members
Volunteer Time Off (VTO) policy to give back and contribute to your local community
Remote or Hybrid work schedule, depending on team and personal preferences
