XBorg powers fan engagement for the world's biggest esports teams - Team Liquid, Ninjas in Pyjamas, JD Gaming, and more. We're building the infrastructure that lets these organizations create personalized, gamified experiences for millions of fans. Incubated by SwissBorg with $10M+ raised, we're now expanding beyond gaming and entering the AI race with a new product that will change how the world's largest brands engage with their audiences. The Technical Context While most of our infrastructure is traditional web2 ( Nest.js , PostgreSQL, AWS), some of our fan applications live on-chain: Team Liquid's fan app runs on Sui, Ninjas in Pyjamas on Chiliz. This means our backend needs to bridge both worlds seamlessly. We're not looking for a blockchain maximalist or someone who wants to rebuild everything on-chain. We're looking for a strong backend engineer who can navigate the blockchain layer when needed - whether that's integrating with smart contracts, managing on-chain/off-chain data sync, or optimizing how we leverage developer tools native to the various blockchains we integrate. So while you will spend most of your time building and shipping exciting new features, some of them will sit at the intersection of traditional backends and blockchain tech.
