Senior Security Engineer - Remote

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 thre…

About the Team This role sits in our Acceleration department, home to the people who drive ecosystem growth by building tools, integrations, and partnerships across the Polkadot network. Reporting into our Polkadot Research Lead, you’ll be joining the Polkadot Research Engineering team. We shape the Polkadot research vision and roadmap, translating ecosystem needs into tools and experiences that accelerate platform adoption. About the Role As a Senior Experience Engineer , you will lead the end-to-end delivery of features, from initial problem discovery to production deployment. This role is designed for a self-directed builder who prioritizes "what" to build as much as "how" to build it. You will leverage an AI-native workflow to iterate rapidly and deliver high-impact solutions to complex user problems. What you’ll do Full-Lifecycle Ownership: Lead feature development through scoping, architecture, deployment, and iteration based on live user data. AI-Augmented Development: Integrate AI tools (e.g., Cursor, Copilot, Claude) into your daily workflow to accelerate velocity and maximize output. Autonomous Decision-Making: Navigate ambiguity by exercising sound judgment, filling requirement gaps without waiting for exhausti…
