Senior Security Engineer - Remote

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!
