Description du poste

Homa is a global mobile game developer and publisher creating games people love. We partner with studios and internally develop games, having launched over 80 titles, reached over 2 billion downloads, and seen our game All in Hole break into the global top-50 grossing charts. These are milestones, not the finish line.

With deep expertise in product and technology, we built Homa Lab, our proprietary platform that gives developers the market intelligence, data tools, and game tech, with AI built-in, to find product–market fit fast and scale mass-market games into lasting experiences players enjoy for years.

This is our flywheel: Homa Lab helps studios spot the right ideas early, turn them into games quickly, and reach millions of players. Every launch brings back data and insights that fuel the next hit, making each turn of the loop faster, smarter, and more likely to win. AI supercharges this process, running through everything we do, from everyday tasks to our guiding principles.

What powers the loop is talent density. 220+ people from 30+ nationalities, bringing expertise from the world’s best studios and companies. We uphold ambition, curiosity, humility, and focus, and deliver with speed, excellence, and candor.

Since the start, we’ve raised $165M from Headline, Northzone, Eurazeo, Bpifrance, and the founders of King, Sorare, and Spotify, people who’ve built and backed the games and platforms we admire, now supporting our drive to create the next ones.

At Homa, we are building the next billion-player experiences from the ground up and shaping the future of entertainment.

As a Creative Developer, you will sit at the intersection of game development, creative production, and performance marketing. Your mission is to use Unity and C# to rapidly modify existing games, prototype new gameplay ideas, and build tools that help the Creative team produce and test high-performing ads faster.

Your main responsibilities will include:

• Modify and prototype gameplay in Unity: new mechanics, visuals, features, UI, cameras, and gameplay variations

Contract setup: This is a full-time freelance opportunity, structured around project needs, with flexible duration depending on the scope and evolution of the projects.

We are looking for someone with years of experience as a Creative Developer or Unity Developer in mobile games.

You're a great fit if you have:

• Strong Unity + C# expertise, confidently modifying existing games, gameplay, mechanics, visuals, and features while debugging and optimizing your work

• Creative + technical mindset, able to turn creative ideas into engaging gameplay variations, prototypes, and high-performing ad concepts quickly
• Strong mobile gaming and creative understanding, with a player-centric approach and knowledge of performance creatives, playable ads, and social/mobile ad trends
• Fast prototyping and iteration skills, balancing speed and quality in a high-volume, test-and-learn creative environment
• Autonomous and collaborative approach, working closely with Creative, Game Dev, and UA teams and using performance data to iterate on concepts
• Bonus: experience with AI-assisted creative/development workflows, Blender, Photoshop, shaders, VFX, or building Unity tools for Creative teams

At Homa, we prioritize talent, energy, and determination over traditional credentials. We’re building a global community of brilliant, driven people who think boldly, act with pragmatism, move fast, and push boundaries. We believe true innovation comes from diverse perspectives, deep collaboration, and curiosity without limits. Our culture is grounded in four core values:

• Humility: We recognise that we are always learning, we can always improve and grow - we stay grounded in a clear view of ourselves.
• Curiosity: We continuously seek the “why” behind the “what” - we explore with purpose and practicality.
• Focus: Our curiosity takes us deeper, not wider - we obsess over the details and let pragmatism guide our attention.
• Ambition: We strive for the best - we don’t settle for “good enough,” - we use common sense to reach higher.

Where We Hire

Our HQ in Paris is a vibrant hub of creativity, collaboration, and connection. From rooftop lunches and coffee chats to after-work apéros and community events, we’ve designed a space people genuinely enjoy - all within a cozy WeWork filled with good energy (and snacks).

We have incredible team members across Europe - from Spain and Turkey to Germany, North Macedonia, Poland, the UK, and more. Whether you’re working from a sunny WeWork in Barcelona or your home setup in Warsaw, you’re fully part of our culture. To keep collaboration smooth, we primarily hire within European time zones (UTC to UTC+3). If you're based there - or planning to be - we’d love to hear from you!
