· Remote, Greater London
Employment Type Full-Time
Minimum Experience Mid-level

This is a fully-remote role from around the world (please disregard the United Kingdom location). Please know that this vacancy is open all year round and will be checked on a rolling-basis.


Want to help welcome the next million developers to blockchain?


Cartesi is looking for Blockchain Engineers, both juniors and experienced!


Who we are

Cartesi is a multi-chain layer-2 infrastructure that enables any software developer to create smart contracts using standard software tools and languages while attaining huge scalability and massive cost savings. Cartesi combines a revolutionary virtual machine, optimistic rollups, and side-chains to transform the way developers build blockchain applications.


Why we are here

Blockchain adoption is a niche. Only 0.1% of developers have explored blockchain because of its inconveniences. Developers worldwide deal with very restrictive environments and cannot code smart contracts with mainstream software. With an operating system like Linux, they could use existing software and tools to create blockchain applications. Cartesi is a layer-2 solution that integrates Linux and standard programming environments to the blockchain, allowing developers to code scalable smart contracts with rich software tools and components they are used to.


“Cartesi bridges the gap between mainstream software and blockchain, welcoming millions of developers to the blockchain.”
