Senior Software Engineer, Cryptography

8+ years of experience in software engineering, with significant depth in systems security and cryptography

Expert-level knowledge of cryptographic protocol design, including key management architectures, certificate systems, and cryptographic agility

Deep experience with hardware security: TPM, TEE, HSM, secure boot, and hardware root-of-trust design across multiple platform types

Experience designing security architectures for embedded, real-time, or robotic systems with constrained environments

Track record of leading cross-organizational technical initiatives and driving architectural decisions that span multiple teams

Experience performing and leading threat modeling, security architecture reviews, and cryptographic design reviews

We're looking for a principal-level engineer to serve as a technical leader for platform security across Anduril.

This role combines deep expertise in cryptography, systems security, and secure architecture with the ability to drive security strategy across business lines and the platform.

You'll own the design of Anduril's most critical security systems — cryptographic infrastructure for autonomous platforms, hardware root-of-trust architectures for robotic systems, secure communication protocols for contested environments — and you'll set the technical direction that shapes how security is built into every product.

This is a role for someone who has designed and shipped security systems at the intersection of hardware, firmware, and software, and can lead others through complex technical decisions with lasting consequences.

Own the technical vision and architecture for platform security across Anduril's product ecosystem

Design cryptographic systems, protocols, and key management architectures for autonomous and robotic platforms operating in contested and disconnected environments

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 scope includes cryptographic protocol design, hardware root-of-trust architectures, secure communication for autonomous and robotic systems, operating system hardening, and distributed security infrastructure across embedded, edge, and cloud environments.
