About The Role

We're hiring a Principal Product Designer to join Smarkets. It's a role with real weight and real freedom behind it: you'll help set the Smarkets products direction and build their core experience from the ground up.

Roadmaps don't get handed down here, and specs don't arrive carved in stone. We want someone who's at their best in open, undefined territory — a designer who treats a blank space as an invitation rather than a void to be feared, and who brings structure, insight and a sense of craft to genuinely hard problems.

You'll work hand in hand with the leadership, product, and engineering teams, owning design end to end: getting to know our users, shaping the narratives the product tells, and shipping precise, carefully considered interfaces.

What you will do:

• Design autonomously. You’ll define and drive design work from scratch - identifying what needs to be done while raising the quality bar. You’ll be working closely with execs, product, engineering.

• Simple interfaces. Designing products that solve problems in a simple and elegant way while taking care of every small detail, from wire-framing to designing end-to-end flows and prototypes

• Design for clarity and depth. Our product touches prediction and betting markets across many categories e.g. sports, politics, current events, technology etc. Your job is to make these powerful tools feel accessible, intuitive, and engaging.

• Prototype quickly and test ideas. You’ll use tools like Figma, Cursor, and light code to explore concepts, validate assumptions, and refine interfaces based on real feedback.

• Develop insights through research. You’ll talk to users, analyse behaviour, and extract meaningful patterns that inform product direction.Running guerrilla and customer testing workshops

• Enhance our design system for both of our products. You’ll redefine the standards and systems that keep our products cohesive as they grow.

• Act as a force-multiplier. You’ll raise the bar - not just through your own work, but by modeling great thinking, process, and collaboration across the company.
