Description du poste

Overview

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. 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.

Team

The Java team provides core components to our gaming infrastructure. We work closely with LiveOps managers, game developers, SDK and data teams to align technical solutions with business needs while providing services to millions of players.

Mission

As a Staff Engineer, you will be a key technical leader in our LiveOps squad, driving architectural decisions, optimising systems, and mentoring engineers. You will be responsible for designing, developing, and scaling critical back-end services that support millions of players daily. If you are looking for a position where you will have the freedom to rewrite core components, participate in the design and implement new features, and significantly impact the team, then this might be the job for you!

We are looking for someone with proven expertise in software engineering and a drive to have impact and learn fast. You’re not just ticking boxes—you’re curious, ambitious, and excited by the challenge of making games that millions will love.

What you’ll thrive here

• 10+ years experience in Java or another JVM language.
• Proven ability to design and optimize high-performance, scalable systems handling millions of daily requests.
• Hands-on experience with mobile gaming, multiplayer services, and/or LiveOps.
• Ability to own high-level technical decisions and align architecture with business goals.
• Strategic Mindset – proactive in diagnosing and resolving complex issues
• Fluent in English with excellent communication skills.

Good to have

• Deep knowledge of the Spring Framework.
• Expertise in resilient software design and fault-tolerant architectures.
• Understanding of stream processing (Kafka, Spark, etc.).
• Experience with key-value stores (Redis, DynamoDB, Aerospike, etc.).
• Strong background in microservice architecture patterns.
• Proficiency in test-driven development (TDD) and automated testing.
• Hands-on experience with Kubernetes or other container orchestrators.

We welcome applicants who may not check every box. We value diverse perspectives and backgrounds, and we’re more interested in your potential and passion than a perfect match to a checklist.

Our Culture

At Homa, talent density is at the heart of everything we do — we’re building a global community of brilliant, driven people who think boldly, act fast, and push boundaries. We believe true innovation comes from diverse perspectives, deep collaboration, and curiosity without limits. That’s why we prioritize talent, energy, and determination over traditional credentials. Together, we harness the power of extraordinary minds to build games players love — and to shape the future of mobile gaming. We live by four core values:

• Ambition: We strive for the best — we don’t settle for “good enough.”
• Humility: We recognize that we are always learning, we can always improve and grow
• Curiosity: We continuously seek the “why” behind the “what”
• Focus: Our curiosity takes us deeper, not wider – we obsess over the details
