Senior Offensive Security Engineer, Rust, Peer to Peer

Job Description: - Live within the engineering team; design and build secure features throughout the software development lifecycle.

• Participate in architecture and design reviews, identifying security risks early and collaborating with engineers on practical, scalable solutions.
• Contribute production-quality code in Rust and other languages as needed to implement security-critical functionality.
• Design and implement secure communication patterns, authentication mechanisms, and cryptographic services for decentralized systems.
• Evaluate new product features for security implications and recommend design improvements before implementation begins.
• Perform security-focused code reviews with an emphasis on exploitability, resiliency, and secure implementation patterns.
• Lead implementation efforts to remediate vulnerabilities discovered through internal testing, penetration testing, or external assessments.
• Work with engineering teams to prioritize security improvements while balancing performance, usability, and product requirements.
• Design, implement, and improve security controls for peer-to-peer networking, distributed protocols, edge AI workloads, and device-to-device communications.
• Serve as the dedicated security engineering partner for the IDN team, influencing architecture, implementation, and vulnerability remediation activities across the platform.
• Conduct threat modeling exercises for new platform capabilities, distributed protocols, network services, and architectural changes.
• Assess security implications of peer discovery, node identity, trust establishment, relay services, NAT traversal, encrypted communications, and distributed trust models.
• Evaluate platform resilience against malicious nodes, protocol abuse, unauthorized access, data manipulation, and other adversarial behaviors common to decentralized systems.
• Partner with architects and engineering leadership to identify and address security risks during architecture and design phases before implementation begins.

Requirements: - 8+ years of experience in software engineering, application security, product security, or secure systems engineering.

• Software engineering experience with Rust, including developing production systems.
• Hands-on experience performing security-focused code reviews and vulnerability analysis.
• Experience embedding with engineering teams and contributing directly to software design and implementation.
• Deep understanding of secure software development practices and secure-by-design principles.
• Experience performing architecture reviews and translating security requirements into engineering solutions.
• Strong knowledge of distributed systems architecture, peer-to-peer networking concepts, trust models, identity systems, secure communications, and modern application architectures.
• Experience implementing or integrating authentication / authorization systems, cryptographic libraries & protocols, secure communications, key management, identity & trust services.
• Demonstrated ability to work collaboratively with software engineers to deliver secure, maintainable solutions.
