About Cinnamon

Cinnamon is the most ambitious independent Roblox studio in the world.

Our games have generated billions of visits, reached millions of players worldwide and continue to grow every day. Our portfolio includes LifeTogether (3.5+ billion visits), Block Spin (990+ million visits) and Bayview (600+ million visits), alongside an ambitious project currently in development.

We build original games. We own our products. We invest in them for the long term.

While many games experience a brief spike in popularity before disappearing, our focus is on building products that continue to grow every single day, retain players and attract large audiences long after launch. We're building games designed to become long-term destinations for millions of players and become legendary.

The Role

We're looking for a talented Gameplay Programmer to build the next generation of Cinnamon games.

This role is specifically aimed at senior gameplay programmers from outside the Roblox ecosystem.

You'll create systems, mechanics and features experienced by millions of players worldwide while working closely with artists, designers and founders.

This is primarily a programming role focused on gameplay systems, multiplayer features, progression systems, optimisation and technical problem-solving.

No Roblox experience is required.

We're particularly interested in developers from Unreal Engine, Unity and proprietary engine backgrounds who are looking for a new challenge.

If you've spent years building gameplay systems, multiplayer features, AI, networking, tools or large-scale game systems, we'd love to hear from you.

What matters most is strong engineering ability, problem-solving skills and a willingness to learn. Roblox is different from traditional game development and some parts of the platform can feel unconventional at first, but we've found great developers adapt quickly.

As a small team, every programmer has a direct impact on the quality and success of our games.

What You'll Do

Design and develop gameplay systems, mechanics and core game features
Build scalable systems supporting large live multiplayer games
Develop progression, economy and player engagement systems
Bring proven game development practices from Unreal, Unity or proprietary engines into a fast-moving Roblox environment
Collaborate closely with artists, designers and founders
Optimise performance across client and server environments
Debug, profile and improve existing systems
Contribute to long-term technical architecture and engineering standards
Take ownership of systems from concept through release

What We're Looking For

Strong software engineering fundamentals
Strong programming skills in Luau or languages that transfer well to Luau
Experience developing gameplay systems, mechanics or major game features
Strong debugging and problem-solving skills
Understanding of multiplayer systems and networking concepts
Experience working on shipped games
Ability to learn new technologies and workflows quickly
Excellent communication skills
Passion for building great games and player experiences
Full-time availability or contract with intent to transition to full-time
UK-based and able to work remotely

Experience with Unreal Engine, Unity, proprietary engines, Roblox, multiplayer games, live service games, networking, optimisation or large-scale online experiences is highly valued.

Why Join Cinnamon?

If you're tired of spending years building games that get cancelled, rebooted or delayed before players ever get to experience them, welcome to Cinnamon.

We're a successful independent studio. We don't rely on investors to decide whether our games get made. We've already built games that have generated billions of visits and continue to grow every day.

We've built some of Roblox's biggest games.

Now we're building the next hits.

At Cinnamon, you'll work on games played by millions of people around the world and see the impact of your work far sooner than traditional game development often allows.

Yes, Roblox runs on Luau rather than C++ or C#, but great programmers adapt. What matters most is strong engineering ability, problem-solving skills and a desire to build great games.

If you're excited by the challenge of learning a new platform, reaching a massive audience and helping create the next generation of Roblox hits, we'd love to hear from you.

What You Get

UK Remote
Flexible working
Company pension
Opportunity to work on games played by millions of players worldwide
Significant ownership and autonomy
Direct influence on products, features and technical direction
Opportunity to apply your AAA, Unreal, Unity or proprietary engine experience to one of the most successful studios operating on Roblox
The opportunity to help build the next generation of Roblox hits

Recruitment Process

1️⃣ All applications are reviewed manually by both our recruiter and internal studio team members.

2️⃣ Selected candidates will be invited to an initial screening call.

3️⃣ Shortlisted candidates will complete a practical Roblox development task. Create mini game on Roblox studio

4️⃣ Final candidates will meet with the founders.

If both sides feel there is a strong fit, we'll move forward with a formal offer and agreed start date.
