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 systems that demand absolute stability and global scalability.
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. Our goal is to build a future where passive viewing is replaced by active, seamless participation. To drive the core logic of our expanding product portfolio, we are now looking for a Game Design Developer.
The Opportunity
As a Game Design Developer at Avanti, you will have the unique opportunity to design and build the very heart of our interactive products. You will be responsible for developing the game servers that power our live experiences, ensuring that every round, interaction, and outcome is governed by robust, high-performance logic. This is a role where your technical decisions directly shape the mechanics and the fairness of the user experience.
You will join a high-growth scale-up where you are not just executing tasks but architecting systems. This role offers the chance to work with complex simulations and validation-heavy environments, where you will run millions of rounds to certify that our systems meet the highest standards of integrity. You will be a key player in a team that values innovation and technical depth, giving you the platform to influence game mechanics and betting logic for products that have never been seen before.
This is an opportunity to take full ownership of the server-side life cycle. You will move from conceptual design to technical implementation, ensuring our servers are secure, efficient, and capable of handling the demands of a global audience in real-time.
Main Responsibilities
Develop and maintain dedicated game servers for various live titles, ensuring unique logic for each game type.
Build and execute large-scale simulations to validate game outcomes and ensure Return to Player (RTP) percentages are accurate.
Design and implement core betting mechanics and game-round logic from the ground up.
Secure the server architecture against external threats and ensure high levels of data validation and penetration resistance.
Collaborate with the frontend and tech teams to ensure seamless communication between the game server and the Unreal Engine client.
Create and manage tools for versioning and running simulations of millions of game rounds to meet certification requirements.
Who we are looking for
We are looking for a developer who finds beauty in logic and thrives on technical precision. You are someone who understands that in a live environment, stability is just as important as creativity. You likely have a "nerdy" passion for complex systems and enjoy the challenge of building servers that are both highly secure and capable of processing massive amounts of data with zero margin for error.
Your mindset is proactive and detail-oriented; you don't just write code, you validate it through rigorous testing and simulation. You are a natural problem-solver who enjoys working in a fast-paced, iterative environment where you are expected to take initiative and own your domain. You are communicative, humble, and enjoy sharing technical insights with a team of like-minded specialists.
Qualifications
Proven experience in backend or server-side development, preferably within igaming or regulated industries.
Strong proficiency in typescript.
Experience of WebSockets and Real-time protocols and implementation.
Experience with DDoS and validation.
Experience in building simulation tools and performing large-scale data validation.
Understanding of game mathematics, betting mechanics, and RTP calculations.
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.
