UI Designer in London

About Cinnamon

Cinnamon is the most ambitious independent Roblox studio in the world. Our games have generated billions of visits. LifeTogether with more than 3.5 billion visits. Block Spin with more than 1 billion visits. Bayview with more than 600 million visits. Built from scratch. Owned outright. Growing every single day. No investors. No shortcuts. Just great games. We're continuing to grow our team throughout 2026 and are looking for exceptional UK based UI Designers to help build the next generation of Roblox games.

The Role

You’ll design interfaces experienced by millions of players. From inventories and shops to progression systems, HUDs and menus, you’ll create interfaces that feel like a natural part of the game world while making every interaction intuitive, satisfying and memorable. You’ll work directly with programmers, designers, artists and founders. On a small team, your work doesn't disappear into a pipeline. It ships. Players use it. It matters.

Freelance Roblox UI Designer

Are you an experienced Roblox UI Designer working as a freelancer or contractor globally? We’d still love to hear from you, even if you are not UK based. When applying, please include your hourly rate or day rate along with your portfolio. If your experience matches what we're looking for, we may get in touch as soon as a suitable opportunity becomes available.

What You’ll Do

• Design high quality user interfaces for Roblox games
• Create polished menus, HUDs, inventories, shops and gameplay interfaces
• Produce layered production ready UI assets
• Help establish the visual identity of our games
• Work closely with programmers, designers and artists throughout development
• Iterate on interfaces through testing and player feedback
• Take ownership from concept through implementation
• Contribute ideas that improve the player experience

What We’re Looking For

• Strong experience designing user interfaces for games
• Exceptional artistic judgement and visual design skills
• Excellent understanding of composition, typography, colour, hierarchy and readability
• Experience creating layered production ready UI assets using Photoshop or equivalent software
• Strong understanding of player experience and usability
• Ability to work independently and take ownership
• Strong communication skills
• Excellent attention to detail
• A portfolio demonstrating high quality game UI
• Based in the United Kingdom with the right to work in the UK

You do not need professional Roblox experience. You do need to be familiar with Roblox Studio before applying. We expect every candidate to download the software, spend time learning the fundamentals and understand the basics of the engine before entering our recruitment process. Roblox Studio is free and straightforward to learn. We do not provide training on the fundamentals.

Artistic Judgement Matters

Technical ability is important. Artistic judgement is what separates good UI from unforgettable UI. Many designers can create a functional inventory. Far fewer can create an interface that immediately feels right for the game. One that communicates information effortlessly and strengthens every interaction the player has. We're looking for designers who understand that memorable interfaces come from strong creative decisions. Not simply more effects, more layers or more decoration. Hierarchy, readability, composition, colour, animation and personality all matter. In many cases, creating the right interface requires less clicking and more thinking.

Why Join Cinnamon?

Most developers spend years working on a game before players ever see the results. At Cinnamon, you'll see the impact of your work in months. We move significantly faster than traditional AAA development, but that doesn't mean we compromise on quality. We believe Roblox deserves the same ambition, creativity and craftsmanship as any major gaming platform. We hold ourselves to that standard every day. We've never relied on investors to build Cinnamon. The studio is funded by the success of the games we've already created. Our products have generated billions of visits and reached millions of players worldwide. That allows us to grow through the success of our own games rather than external funding. Our goal is simple. Build some of the best games on Roblox. We've already generated billions of visits across our portfolio. Now we're building the next generation of games designed to reach billions more. We're highly selective about who joins the studio because every individual directly influences the quality of what we create. If you're excited by the idea of designing products at an elite standard, reaching millions of players and seeing the results of your work far sooner than traditional game development allows, we'd love to hear from you.
