Job description

Avanti operates at the intersection of advanced real-time technology and interactive entertainment. Our mission is to redefine digital engagement by blurring the lines between the virtual and the physical, creating next-generation live experiences driven by hyper-realistic characters and AI-powered interaction. We exist to challenge established truths in the industry, injecting technical brilliance into old infrastructure.

We are here to transform the landscape of live digital experiences by combining the high-fidelity aesthetics of AAA gaming with the complex logic of regulated interactive systems. To drive the core logic of our expanding product portfolio, we are now looking for a Game Server Developer.

The Opportunity

• Collaborate with the frontend and tech teams to ensure seamless communication between the game server and the Unreal Engine client.

Who we are looking for

We're looking for a backend developer who has a mind for the logic of code, math, statistics and tries to build the code as optimized as possible. Your mindset is proactive and detail-oriented, where you validate code through simulations and might be nit-picking CPU usage. You're a problemsolver who likes to work with modular systems where you take initiate and own your area. More than that, you're communicative across teams and enjoy sharing technical insights with the rest of the teams.

• Real-time experience: You know your way around WebSockets and live protocols.
• Experience with DDoS and validation.
• Experience in building simulation tools and performing large-scale data validation.
• Experience with server security, data integrity, and validation-heavy environments.
• Professional fluency in English.

It is a plus if you have

• Experience from the iGaming industry or live casino development.
• Experience of multiplayer-systems
• Understanding of game mathematics, betting mechanics, and RTP calculations.
• Knowledge of certification processes for regulated gaming markets.
• Experience with cloud infrastructure and scalable server deployments.
• Experience or a background in statistics.

Who we are

Avanti is an innovative technology company dedicated to creating the next generation of live interactive experiences within igaming. By combining technical excellence with creative height, we have established ourselves as a respected partner for global clients who demand world-class stability and immersion. We are currently in a strong growth phase, driven by an entrepreneurial spirit and a commitment to quality in every detail.

What we offer

• The chance to work with new tech using a lot of R&D to solve problems.
• A highly collaborative and prestige-less work environment.
• Competitive compensation and benefits package.
