About Us
Parity is one of the world's most experienced core blockchain infrastructure companies, laying the foundation for the new decentralised internet. 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.
We believe in a decentralised web that respects the freedom and data of individuals and empowers developers to create better services. Our vision is to create a world based on truthful, rather than trustful, interactions.
With a remote-first, global team, Parity is building open-source technologies for developers and organisations to implement and build upon. Our Web3 tech stack includes Polkadot, Substrate, and Kusama.
People in Our Collective Are
- Highly motivated to contribute to Parity’s mission and be part of something bigger
- Excited to work on projects that are groundbreaking and complex
- Autonomous workers who self-initiate but also collaborate well
- Accountable and low-ego team players
- Comfortable adapting to the ever-changing Web3 space
- Continuously learning about Parity and the wider ecosystem
About the Team
Parity’s Security Engineering team is at the forefront of protecting the Polkadot ecosystem by designing and implementing secure software, auditing code for vulnerabilities, and building cutting-edge ML tools to automate security analysis. We work closely with development teams to embed security best practices across our open-source stack, ensuring that our blockchain infrastructure is robust, resilient, and secure by design.
About the Role
As a security-focused software engineer, you will go beyond traditional application security - you’ll audit and ideally write secure Rust or C++ code where needed, conduct deep manual and automated code audits, and leverage machine learning to enhance security across our ecosystem. This is an opportunity to shape the security landscape of the next generation of decentralized applications and protocols.
- Assist in developing Secure Software – Write and optimise Rust or C++ code to build security-critical components and tools.
- Code Auditing & Vulnerability Analysis – Perform deep manual and automated code reviews to identify and mitigate security vulnerabilities.
- ML-Powered Security – Design and implement machine learning models for automated security analysis, anomaly detection, and threat mitigation.
- Bug Bounty & Vulnerability Management – Manage bug bounty submissions, triage security reports, and collaborate with ethical hackers to resolve issues.
- Secure Development Best Practices – Work with engineering teams to integrate security best practices into the software development lifecycle.
- Threat Modeling & Risk Assessment – Identify and assess security risks in our blockchain infrastructure, smart contracts, and core software.
- Stay Cutting-Edge – Research and implement the latest advancements in secure coding, ML-driven security, and blockchain security.
What We're Looking For
- Software engineering skills.
- Experience with secure coding practices and memory safety concepts.
- Background in code auditing, vulnerability analysis, or exploit development.
- Experience triaging and resolving bug bounty reports.
- Knowledge of machine learning techniques applied to security (e.g., anomaly detection, fuzzing, automated threat detection).
- Familiarity with cryptographic principles, blockchain security, or decentralized systems.
- Strong problem-solving skills and an offensive security mindset.
If you're excited about writing secure software, auditing code, and pioneering ML-driven security solutions for Web3, we’d love to hear from you!
Those joining our collective as an employee in Germany, Portugal, Switzerland and the U.K. also enjoy benefits such as health care, parental leave, PTO (28 days per year), local team events, yearly L&D budget, and language classes.
Parity is an Equal Opportunity Employer. We welcome diversity in our global team and care about everyone in our collective feeling included and welcome.
