About the Team

The Sell Online team builds the products that help small business owners run and grow their businesses online - from appointment bookings and online stores to customer management. We're a cross-functional design team embedded across multiple product squads, working closely with product managers and engineers to shape experiences used by millions of merchants worldwide.

• Work across multiple squads simultaneously, collaborating closely with product managers, engineers and other designers
• Contribute to and evolve our design system, ensuring consistency and scalability as the product portfolio grows
• Use qualitative research and user data to inform design decisions and validate solutions

You'll Be Great for This Role If

• You have experience designing for customer-facing products on both web and mobile, ideally in e-commerce, bookings, or similar consumer contexts
• You have proven ability to work with and contribute to design systems at scale
• You are comfortable managing multiple workstreams and stakeholders across different product areas
• You have a collaborative, curious mindset
