Ethereum L1 Blockchain Engineer

$29k - $60k · Senior Full-time Posted about 4 years ago 3 min read

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 launching on the Celo platform, Valora, is a social payments and money transfer app, aimed at developing markets.

cLabs is seeking an Ethereum L1 Blockchain Engineer. Our team is responsible for maintaining Celo's blockchain client gocelo. This is the core software that validators on the Celo network run to peer with each other on a p2p network, reach consensus on new blocks, and create the fundamental platform upon which the Celo community builds user-facing applications.

Our client is based on go-ethereum (or geth), the Go implementation of the Ethereum client, with several key improvements such as the switch from Proof-of-Work to Proof-of-Stake. Our main challenges are scaling the network, improving its security and resiliency, and adding new features to the Celo ecosystem that can only be done at the client level (like paying gas fees with an ERC-20 token).

We work alongside other engineering teams within cLabs. This includes other platform teams such as the Contracts and Primitives team, as we constantly access smart contracts as part of our operations, and the Economics team, to design and implement the right incentives for our validators and full nodes. We also partner with user-facing teams such as the Wallet and Developer Experience teams, as a big part of our job is to make end users' and contributors' lives easier. This is a role with wide exposure to many areas of the stack, and you'll quickly get acquainted with all the moving parts in a modern blockchain project.

cLabs ("Celo Labs") started Celo in 2017 and is one of many contributors to the open source project Celo. cLabs builds financial technology to enable prosperity of all beings.

cLabs is a Teal organization, a method of decentralized management and organizational governance. Roles are defined around the work, not people, and there is a high degree of autonomy. As such, we're all proud to hold the job title of "Partner." For more information on our culture, we encourage you to check out our blog at https://medium.com/celohq/the-future-is-teal-cc264a5d51d3.

To build technology and products that are used and loved by people and solve real-world problems, we need to build a team with many different perspectives and experiences. We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status. We encourage candidates from all backgrounds to apply and always consider qualified applicants with arrest and conviction records, in accordance with the San Francisco Fair Chance Ordinance.

Applicants in need of special assistance or accommodation during the interview process or in accessing our website may contact us by sending an email to assistance(at)celo.org. We will treat your request as confidentially as possible. In your email, please include your name and preferred method of contact, and we will respond as soon as possible.
