We are looking for a talented and ambitious Product Designer to join an empowered product team and own the user experience across our flagship product suite. You will be the creative force shaping how the world’s largest brands experience System1’s Ad, Brand and Innovation products, working as a first-class member of the product trio alongside your Product Manager and Tech Lead to discover and deliver outcomes that matter to our customers and our business.

This is a rare opportunity to define the design function from the inside out, lean heavily into AI-powered design, and work at the speed our market demands.

• Are you energised by being a true partner in the product trio, helping decide what to build, not just how it looks?
• Are you already using AI-native tools (Claude Design, Figma AI and the next thing that ships next month) to run faster discovery loops and ship more confidently?
• Are you motivated by outcomes over outputs, and by tackling hard product risks rather than shipping features for their own sake?

• Partner as an equal member of the product trio (Product Manager, Product Designer, Tech Lead), sharing accountability for the outcomes your team commits to.
• Lead continuous product discovery alongside your PM. Tackling the four big product risks (value, usability, feasibility, and business viability) before we commit to building.
• Own and elevate the end-to-end user experience across System1’s product suite (Ad, Brand and Innovation) so it becomes the most loved experience in our category.
• Use AI-powered design tools (Claude Design, Figma AI and equivalents) to compress discovery and delivery cycles, turning ideas into testable prototypes in days, not weeks.
• Run frequent prototype-based experiments with real customers to test value and usability before code is written.
• Build, evolve and maintain our design system so every product feels coherent, fast to ship against, and unmistakably System
  1.
• Partner on customer research. You don’t need to be a full‑time researcher, but you do need to know how to talk to customers and turn what you hear into better product.
• Champion the customer inside the business, bringing real customer evidence into every product decision, prioritisation call and stakeholder conversation.
• Set the bar for design craft, speed and rigour across the company and define what “great” looks like as the function grows around you.

• A missionary, not a mercenary. You care deeply about the customer problem and the outcome, not just the deliverable.
• Outcome-driven. You measure your success by the change you create for customers and the business, not by features shipped.
• Speed-obsessed in discovery. You instinctively reach for the fastest path to a testable prototype, and you treat AI tools as an extension of your craft, not a threat to it.
• Comfortable with ambiguity and ownership. You don’t wait for a brief, you frame the problem worth solving with your trio and go.
• Curious and a lifelong learner, with the integrity to back your point of view with evidence in front of colleagues, customers and stakeholders.
• Able to see the bigger picture without losing attention to detail, your pixel craft is as strong as your strategic thinking.
• A natural collaborator, comfortable working with all departments at all seniorities, and equally able to drive work forward independently.
• Passionate about (good!) advertising, how it works and how it can be improved or excited to become so.
