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.

Please mention the word **FEASIBLE** and tag RNDEuMTE1LjEyNy4xODY= when applying to show you read the job post completely (#RNDEuMTE1LjEyNy4xODY=). This is a beta feature to avoid spam applicants. Companies can search these words to find applicants that read this and see they're human.

How to apply
When applying for jobs, you should NEVER have to pay to apply. You should also NEVER have to pay to buy equipment which they then pay you back for later. Also never pay for trainings you have to do. Those are scams! NEVER PAY FOR ANYTHING! Posts that link to pages with "how to work online" are also scams. Don't use them or pay for them. Also always verify you're actually talking to the company in the job post and not an imposter. A good idea is to check the domain name for the site/email and see if it's the actual company's main domain name. Scams in remote work are rampant, be careful!
