👋 About Us

sunday is building the fastest, simplest way to pay in restaurants. With a quick scan of a QR code, diners can pay, tip, and leave in about 10 seconds. We believe great products should feel obvious, not complicated, and we focus relentlessly on keeping things simple while earning trust from restaurants and guests at every interaction. Today, sunday powers payments in thousands of restaurants across the US, UK, and France, helping operators turn tables faster, increase tips, and unlock valuable insights. We push ourselves to go beyond what’s expected, building with ownership, moving fast, and scaling with ambition as we tackle our biggest growth opportunity in the US.

About the Role

As sunday's first People Partner fully dedicated to the US, your ultimate goal will be to build and run a world-class HR function that empowers employees, gives US managers a trusted partner on the ground, and protects the company. With 50+ employees across 7 US states, sunday is at an inflection point: managing payroll, multi-state compliance, and benefits enrollment from Europe is no longer sustainable. You'll own the full US HR scope, from operational excellence in payroll and compliance to strategic business partnering. Join early, grow fast, and shape the journey!

Key Responsibilities

1. Own and operate end-to-end US payroll across 7+ states: ensure every pay cycle runs on time with zero errors, manage deductions, tax filings, and reconciliations with full accuracy

2. Administer US benefits programs (medical, dental, vision, 401(k)): manage open enrollment, onboarding, and day-to-day employee queries with a seamless experience

3. Ensure multi-state HR compliance: audit current practices, identify gaps, and build scalable, documented processes in line with federal and state employment laws (FMLA, ADA, wage & hour, state leave laws)

4. Serve as the trusted HR Business Partner for US managers and employees: provide expert guidance on performance management, employee relations, and HR policy

5. Own HRIS administration and reporting: configure workflows in US HR and payroll platforms (HiBob, ADP or equivalent), track key HR metrics, and surface insights proactively

6. Support performance cycles and engagement initiatives: coordinate review processes, run US-specific people programs, and contribute to building a strong team culture

7. Act as the primary point of contact for external US HR vendors and partners: manage relationships with PEO providers, benefits brokers, legal counsel, and compliance advisors
