Software Engineer (Parachains Core) - Full-time

About Us

Parity is one of the world's most experienced core blockchain infrastructure companies, having built and pioneered some of the most advanced technologies in the blockchain sector. Parity was founded by Dr. Gavin Wood, co-founder and former CTO of Ethereum, the primary engineer behind the Ethereum Virtual Machine (EVM), inventor of the Solidity programming language, and primary author of the Ethereum Yellowpaper.

Based in Berlin, London, and Lisbon, Parity has built clients for Ethereum, Bitcoin, and Zcash and has pioneered a completely new, next-generation blockchain protocol with Polkadot and the framework it’s built with, Substrate. Parity builds the open-source technologies needed to power an unstoppable, decentralised web—known as Web3—and helps developers and organisations implement and build upon the Web3 tech stack.
