Senior Embedded Security Engineer

About the role

We're building the next generation of decentralized, on-edge AI infrastructure—software that runs securely where data is created, not where it's collected. Our platform enables private, sovereign AI through peer-to-peer networking, edge computing, and modern distributed systems. We're looking for a highly technical Embedded Security Engineer who thrives at the intersection of software engineering and cybersecurity.

Responsibilities

• 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.
• Work with engineering teams to prioritize security improvements while balancing performance, usability, and product requirements.
• 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.
• Partner with architects and engineering leadership to identify and address security risks during architecture and design phases before implementation begins.

Qualifications

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