Senior GTM Engineer

👋 About Us

sunday is the fastest way to pay in restaurants. We turn the painful 15-minute process of paying at a restaurant into an effortless experience. With just a QR code, customers pay in 10 seconds, and restaurants turn tables faster, get more tips for staff, and collect precious data.
