The Role: Senior Product Designer (Part-Time)

We’re looking for an experienced Senior Product Designer to help shape the future of Countingup – on a part-time basis.

You’ll work across the full product design lifecycle, from discovery to delivery, in close collaboration with product managers, engineers, and our Head of Design. You’ll lead design on a product team, using insight and creativity to solve real problems for real people.

This is an ideal role for a designer who wants meaningful part-time work with high impact – and the autonomy to get on with it.

We work hybrid, with at least one day a week in our Central London office and flexibility the rest of the time.

• Plan and run usability testing and help shape iterative release plans
  
• Collaborate post-launch to monitor, measure and evolve your designs
  
• Document design logic and apply a systematic approach to your work
