Lead Blockchain Security Engineer Full Time (Remote)

Massa Labs develops the first blockchain that is both truly decentralized and scaled. After launching a testnet attracting 3,000 nodes and raising €5m in a private sale round this summer, the team is now growing to prepare for the mainnet launch expected in 2022, as well as future challenges.

Massa uses a novel parallel blockchain protocol designed over 3 years of research, that was shown to scale to thousands of operations per second while supporting thousands of nodes. The core blockchain software is written in Rust, and the smart contract engine features several innovations such as autonomous smart contracts, on-chain website hosting, and a Wasm bytecode allowing to write smart contracts in many languages.

We are doing stuff no one else is doing, and are looking for people who are not afraid to challenge common ideas and practices in this space.

At Massa Labs you will lead the security team in charge of the analysis and improvement of the security of the core protocol and its implementation. Your team will identify security weaknesses in Massa and other blockchains, suggest improvements, help in their implementation, and more generally keep up-to-date with the latest blockchain security practices, tools and vulnerabilities. Your work will mostly focus on p2p networking, the bootstrapping process, the consensus algorithm and the smart-contract engine.
