Conversion is hiringUI/UX Designer

Full TimeUI/UX Design
Posted 4mo ago



Conversion is the largest dedicated conversion rate optimisation (CRO) and testing agency in the UK. We help our clients better understand their customers - and translate this insight into action. As a business, our focus is on helping clients create an unfair competitive advantage through testing.

We believe that testing is not about changing button colours, but about creating a testing framework that allows our clients to take calculated risks. This approach allows us to test not only our clients’ websites and apps, but also their pricing, product, and strategy. The nature of testing means that we can definitively demonstrate and deliver ROI for our clients.

Our team is made up of a number of specialists and generalists with skills spanning: copywriting, behavioural psychology, user research, analytics, UX design, frontend development, and project management.

We’ve delivered results for clients ranging from one-person lead generation sites to the likes of Canon, Dominos, and UNICEF.

We have grown significantly over the last few years and are investing in the next stage of our growth to help us achieve our goal to help our clients start testing everywhere.


You will be a key player in one of our 8 pods consisting of a Consultant, an Associate Consultant, a Developer, a Project Manager, a QA engineer, and you, the Designer.

You will work closely with the consultants to understand the user insights they have gathered and the conversion optimisation strategy they have created for each client. You’ll use these findings to form A/B test executions that you feel will best answer the experiment hypotheses. You will be responsible for creating wireframes and designs and pitching those ideas to both the consultant and the client.

Along the way, you will learn all about CRO and develop an experimentation mindset that will help set you apart from other designers.


Client delivery: working across up to six client accounts leading the delivery of wireframes and designs;

  • Lead the design of individual experiments
  • Build strong relationships with your clients’ designers
  • Work with the consultant and wider team to find the best execution in order to test a given hypothesis.
  • Understand and apply brand guidelines to client projects
  • Apply high design standards to all projects i.e. visually express hierarchy, construct consistent layouts, display a good knowledge of web typography, and demonstrate a good understanding of responsive design.
  • Work closely with the Developer to enure design are handed off 
  • Actively discuss and challenge experiment ideas.

Support and thought leadership: Act as the support designer for Junior Designers where needed. You are also expected to identify opportunities for pod and departmental improvement and work with the wider team to execute on those ideas.

Collaboration: Work collaboratively with the rest of the design team and your pod to deliver quality work in a time-effective manner. Look for opportunities to support your team and help things run as smoothly as possible. You should be ready to provide feedback on test designs & ideas and be an active member of the team. This could involve things such as contributing your ideas in meetings - whether test ideas and design executions for clients or trying to optimise our internal processes. 

Internal projects: Lead and deliver internal projects with an understanding of the company’s brand. This may include marketing material such as blog images, event banners, whitepapers, etc. but also our own tools, dashboards, and product branding.

Learning: Absorb as much knowledge about CRO, UI, and UX design as possible. As part of this journey, you should expect feedback from the team & seek it out actively. You should be vigilant in filling in any knowledge gaps and staying on top of industry trends.
