We’re Red Tiger, a dynamic and self-contained team within the vast Evolution ecosystem, thriving with 200 talented professionals based in Sofia. Our expertise spans from product inception to final development, covering product, art, development, and more. Proudly 100% made in Bulgaria, we take immense pride in our achievements, adaptability, and the high quality of our games.

Job Description

We’re looking for an R&D Game Developer to join a team that handles the weird, new, and not-yet-fully-defined technical challenges that come up across the company.

This is not a narrow role where you only work on one part of the product. The work can touch pretty much anything: frontend, backend, DevOps, tooling, prototypes, internal game components, performance, rendering, automation, and whatever else the next unusual problem requires.

That said, there is a stronger emphasis on the frontend side, since that’s where much of the complexity usually lives in our games.

We’re looking for someone who enjoys figuring things out from first principles, jumping between different technical areas, and working on problems where the path is not always obvious from day one.

You’ll help research, prototype, and build solutions for new technical challenges across our game development work.

That can include:

Building and improving game-related frontend components
Working on backend parts when needed
Creating tools, prototypes, and internal utilities
Investigating technical unknowns and proposing practical solutions
Improving performance, game architecture, and developer workflows
Touching DevOps, build pipelines, deployment, and infrastructure when the task requires it
Working closely with other engineers to solve problems that do not fit neatly into one category

Qualifications

You should be comfortable with the basics of how computers, browsers, programming languages, networks, memory, performance, and software architecture work. You don’t need to know everything, but you should be curious enough to learn quickly and technical enough to reason through unfamiliar problems.

Good candidates usually have:

Strong programming fundamentals
Solid JavaScript or TypeScript experience
Good understanding of browser behavior and frontend performance
Ability to work across different technical areas when needed
Comfort with debugging complex or unfamiliar code
Practical backend knowledge
Basic DevOps awareness
Interest in games, rendering, tooling, or engine-like game components
A mindset focused on understanding, not just copying patterns

Bonus points:

It would be a big plus if you have experience or interest in:

Graphics programming
WebGL or OpenGL
Pixi.js
Browser rendering internals
Game architecture
Performance optimization
Animation
Build tools and developer tooling
Low-level programming concepts
