About Us
Parity is one of the world’s most experienced companies building the core infrastructure behind blockchain — the system that allows information and value to be shared securely without needing an intermediary. We’re laying the foundation for a better web which respects the freedom and data of individuals, and empowers developers to build better, more trustworthy online services.
Our remote-first, global team develop open-source software that anyone can use or improve. This includes Polkadot, Substrate, and Kusama — key parts of the Web3 tech stack, the next generation of the internet. Our mission is to make Polkadot the most active and innovative community in blockchain, powering a new era of connected and decentralised applications.
About the Team
The Security team is pivotal in helping infrastructure and release management teams to secure our networks, operating systems, containers, pipelines and code. We are part of the Security team with a mission of reducing the impact of threats to Parity and its products, bolstering their resilience against potential cyber threats.
About the Role
This is a crucial role where your understanding of people, systems, and security will allow you to advocate for and influence best practices in a diverse free thinking organisation while facilitating smooth development and implementation processes. It is a unique opportunity to help secure an innovative organisation where feedback is direct and honest and understands that a check box approach doesn’t get results.
