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

With player actions sent as on-chain transactions, our games demand a level of throughput yet to be found common in the entire crypto space. As a result, we are looking for a blockchain infra engineer to build and scale our core on-chain game engine and rollup architecture. This includes creative ways to balance on-chain and off-chain computation and storage with composability and player asset security in mind, as well as load testing for corresponding architectural decisions.
