Senior Distributed Systems Engineer
Posted on Wednesday, May 5, 2021
cLabs is seeking a Senior Distributed Systems Engineer to join our Blockchain Team. Our team is responsible of the Celo's blockchain node; that is the software that maintains a p2p network; where the validators reach consensus new blocks, that then every other nodes syncs & validates. Our node is based on go-ethereum software with several transformations (like the consensus engine) that makes the Celo blockchain unique. 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 node's level (like paying gas with an ERC20 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.
- Design, architect & implement solutions within the celo blockchain (layer 1 & 2), solutions examples include but are not limited to network protocols, decentralized protocols, systems throughput optimisations, scalability.
- Collaborate with Product Team to hit key product milestones by writing high quality, well tested code
