Job description

At Avanti, we are redefining the live casino experience by merging high-end technology with seamless interactivity. Our vision is to transform how people engage with digital entertainment, moving away from static platforms toward dynamic, real-time environments that feel alive and responsive. We exist to solve the complexity of live digital interaction, ensuring that every bet, every move, and every game round is delivered with absolute precision and technical excellence.

Our purpose is to build the architecture that allows for hyper-realistic and reliable gameplay at scale. To achieve this ambitious goal and connect our users directly to the action, we are now looking for a Game Client Developer to join our team.

The Opportunity

As a Game Client Developer at Avanti, you will hold a key role at the heart of our product development. you will be the "middle-man" for all communication—the link that connects our Live Experience, Game Tech, and the Platform. This is a unique chance to work in a role with the broadest overview of the organization, where your code directly enables users worldwide to interact with our games in real-time.

You will be part of building the game development frameworks of the future. Instead of just maintaining existing systems, you will drive constant R&D to create leaner libraries and boilerplates that make our development journey smoother and more scalable. Your work will have a direct impact on how sustainably and efficiently we can roll out new game titles in our portfolio.

In this environment, you will have the space to grow as technology is constantly adapted and evolved. You won’t just write logic for game starts and bet management; you will also influence the graphical interface and the rules that govern the experience. This is a role for someone who thrives with high ownership and wants to see the results of their work in a live, high-performance product.

Main Responsibilities

• Develop and implement user interfaces (UI) and graphical elements for all game titles.

• Build and refine a lean framework and boilerplates to streamline future game development.

• Take responsibility for client-side logic regarding game starts, bet management, and compliance.

• Manage real-time communication and data streams via WebSockets and WebRTC.

• Integrate third-party solutions and handle post-messaging for seamless platform communication.

• Collaborate with the product team to translate design ideas into technical game statistics and rules.

• Create sustainable systems that allow non-technical staff to administrate parts of the game environment.

Who we are looking for

We are looking for a social and outgoing team player who thrives in the role of a technical communicator. As you act as the bridge between several different teams, you must be comfortable explaining complex technical concepts to colleagues with different expertise without losing the technical nuances of the dialogue. You have a natural drive and the ability to take full responsibility for your domains in a fast-paced environment.

To succeed in this role, you need to be organized and capable of managing multiple parallel deadlines as our game portfolio grows. We value "self-drive," where you identify the next steps yourself and proactively seek feedback from relevant teams. You are someone who sees challenges as R&D opportunities and is attracted by the need to constantly adapt your methodology to the latest technology.

Qualifications

• Excellent knowledge of HTML and TypeScript.

• Documented experience with real-time data and handling WebRTC.

• Strong understanding of REST APIs and communication via WebSockets.

• Experience in responsive design to ensure a seamless experience across all devices.

• Ability to write and implement complex game logic and rules.

It is a plus if you have

• Experience with modern frameworks such as Angular or React.

• Previous experience within iGaming or Live Casino.

• Experience in developing multiplayer systems.

• A central role in the organization with contact points to the majority of teams.

• Competitive salary with a target around 60,000 SEK.

• A culture characterized by collaboration, openness, and technical curiosity.
