Senior Product Designer - UK

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

We’re looking for a Senior Product Designer who loves turning complex problems into simple, elegant, and intuitive experiences. You’ll work hand-in-hand with Product Managers and Engineering Managers to shape how thousands of restaurants and guests interact with sunday’s products every day. As the design owner for your squad(s), you’ll drive the full process from discovery to delivery, defining problems, testing ideas, and crafting solutions that make a real difference for users and the business. You’ll be part of a team that believes great design should do one thing above all: save people time, so they can focus on what really matters. Join early, grow fast, and shape the journey!
