Vision and Mission For decades, the line between technology and entertainment has blurred, but in the world of live gaming, true innovation has often remained on the surface. Avanti exists to change that by merging advanced game development with real-time live streaming. We aren't just building games; we are creating a new category of interactive experiences where technical complexity meets human presence. Our goal is to challenge the industry's status quo by using the power of Unreal Engine 5 and MetaHuman technology to deliver a level of quality previously thought impossible in web-based environments. We believe in a future where digital environments are as responsive and believable as the physical world, and where every technical decision is aimed at deepening user engagement. To ensure our future growth and maintain the highest level of delivery as our portfolio expands, we are now looking for a Product Designer who wants to bridge the gap between product logic and market communication.

You will have the unique opportunity to work across the entire spectrum of the product—from deep UI/UX logic within our games to the visual narrative we present to the market. This is a position designed for growth; you will start by working closely with our Head of Product Design to understand our DNA, eventually taking ownership of modularizing our workflows to future-proof our production. You will be part of a team that values technical fearlessness and creative disruption. Your work will directly impact how users interact with complex game elements, ensuring that every interaction—from a chat emoji to a high-stakes betting interface—is as intuitive for the player as it is for the system. We offer a space where you can see the direct results of your creativity through data-driven A/B testing and rapid product iterations. This is more than a design role; it is an invitation to help build the creative engine of a company at the absolute technical frontier.

Act as a "Brand Guardian" to ensure visual consistency across all product and marketing touchpoints. Maintain rigorous digital asset management and documentation to ensure organizational efficiency and easy access for all departments. Who We Are Looking For We are looking for a proactive and someone who finds joy in creating order out of chaos, whether that means establishing strict naming conventions in Figma or organizing complex asset structures in the cloud. You don't wait to be asked for the next step; you are already identifying trends and suggesting improvements as they become a necessity. Your mindset is rooted in self-organization and a deep care for the craft. You collaborate tightly across teams and understand their needs, and see how their work and yours effect eachother. As Avanti evolves quickly, you are motivated by the fact that your input directly shapes the outcome of the product and the efficiency of the entire creative department. Qualifications.
