Parity · Remote
Parity is a global company focused on building core infrastructure for the blockchain ecosystem, specifically contributing to projects like Polkadot and Kusama. As a Senior Security Engineer, you will play a critical role in maintaining the integrity of this open-source stack. Your day-to-day responsibilities will involve conducting deep manual and automated code audits to identify vulnerabilities, writing and optimizing secure Rust code, and developing machine learning models for automated threat detection and anomaly analysis. You will also manage bug bounty programs, triage incoming security reports, and collaborate with development teams to integrate security best practices throughout the software development lifecycle. This role is well-suited for an experienced security professional with a strong background in memory safety, exploit development, and cryptographic principles. Candidates should possess an offensive security mindset and a genuine interest in the decentralized web. This is a remote, contract-based position that requires the ability to work independently while contributing to a global, collaborative engineering environment.
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 , Polkadot SDK , 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 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 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 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 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! About Working With Us Joining Parity means joining team mates who are genuinely excited about the impact their projects are having, and the opportunity to grow alongside some of the brightest minds in the Web3 space! You’ll work remotely and flexibly, while still getting to meet your team mates throughout the year at team and company-wide retreats.
