Apply

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 and asynchronous 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 analysis and improvement of the performance of the core protocol. Your team will analyze the theoretical performance of the architecture and its implementation, monitor the performance of the software running in a real p2p production network with thousands of nodes, identify bottlenecks, suggest improvements and help implement them. The main targets are the p2p network, the bootstrapping process, the consensus algorithm and the smart-contract engine.
