Smart Contracts Engineer

At cLabs, the team working on the open source platform Celo, our mission is to build a financial system that creates the conditions for prosperity for all.

Celo aims to remove the barriers for large-scale adoption of cryptocurrencies as means-of-payment. Using a novel address-based encryption algorithm, the Celo protocol makes sending money as easy as sending a text. Additionally, Celo uses stable-value tokens pegged to fiat currencies, like the US Dollar, to minimize volatility. Celo is an open protocol enabling many to participate in the system, even with a budget Android smartphone. The first application incubated by the internal team at cLabs and successfully spun-out on the Celo platform, Valora, is a social payments and money transfer app, aimed at developing markets.

cLabs is seeking a Smart Contracts Engineer to join our Contracts Team.
