Entry Level React Developer



Casper Labs is ushering in the next era of blockchain technology. In just over three years, we’ve already built an entirely new blockchain and attracted some of the world’s largest organizations to start building with us. On March 31, 2022 we celebrated the one year anniversary of the Casper blockchain mainnet launch, marking several milestones. Now, it’s time to scale — and we’re looking to add world-class engineers, marketers, and operators to our team.


Blockchain technology is estimated by Gartner to be a $1.5 trillion (not billion) market by 2025 and $3 trillion by 2030. Business applications of blockchain solutions across multiple industries will make up the bulk of new adoption, giving Casper blockchain and CasperLabs a first mover advantage.

Why Casper? The co-founders and team of engineers built the most technologically advanced blockchain for business and underpinning this enterprise-grade technology is CasperLabs, a professional services and support team made up of experienced technology leaders. It is their mission to help steward business adoption of blockchain solutions built on Casper while maintaining and evolving the technology.
