Senior Software Engineer (Platform Security)

About this role

• The Platform Security Engineering (PSE) team builds security into Anduril’s products from architecture through production
• We work directly with business lines to design and implement security solutions tailored to their systems — then promote proven patterns into shared, composable platform services that the entire organization can use
• Our mission is threefold: build security solutions for business lines, promote those solutions into the platform, and enable teams to build and operate securely on their own
• The work spans cryptographic protocols, operating system hardening, secure boot, hardware security integration, authentication systems, and distributed protocol security across embedded, edge, and cloud environments
• We’re looking for senior and staff-level software engineers to design and build security solutions across Anduril’s product ecosystem
• You’ll partner directly with business line engineering teams to understand their systems, threat models, and security requirements — then design and implement solutions that range from custom, business-line-specific implementations to shared platform services
• The problems you’ll work on span the full stack — secure hardware, operating systems, container orchestration, distributed services, and cloud infrastructure — and you’ll move between them as the mission demands
• We value engineers who are strong generalists: comfortable learning new domains quickly and working across security boundaries rather than specializing in just one
• Design and implement security features and services for business line products — including custom solutions when platform capabilities don’t yet exist
• Identify patterns across business line implementations and promote them into shared, composable platform security services
• Build tooling, libraries, and reference implementations that enable engineering teams to adopt secure patterns independently
• Lead security architecture reviews and threat modeling for business line and pl...
