About us

At Curio, we’re building the next-generation of games, starting with our first on-chain 4x strategy game. Imagine a virtual world where large-scale battles take place, where players compose smart contracts and invent unseen policy systems over the virtual world's political landscape, and where you may launch economies of your own backed by real currencies, for the empires you lead.

We’re all-in on composability — the ability to let players contribute in-game content in an open manner, through code as well as low-code tools. We are scaffolding the foundation of these future games to come, such as our in-house fully on-chain game engine on the EVM. Thousands of players have already experienced our demo built on top of it. These advancements radically shift the way players interact with the virtual worlds that they hold dear.

We’re backed by the best in the space, including Bain Crypto, TCG Crypto, Robot Ventures, and a team of amazing angels who hail from Niantic, Coinbase, and more. We work in-person in an office in San Francisco. We prefer candidates located in or willing to relocate to the Bay Area, but we also welcome remote candidates with strong fit to what we're building. Join us!

About the role

We are looking for a full-stack engineer to build and improve our client and API stack which interacts with our fully on-chain games. Potential tasks include game UI and animations, interactive panels for creating in-game social plugins, and efficient caching for intermediate game states. This role will be a good opportunity to gain experience in client-server interactions of a new paradigm of gaming and blockchain applications focused on composability.
