Staff Software Engineer, Cryptography

Anduril Industries•Seattle, MA

About The Position

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.

Requirements

10+ 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
Proficient in two or more of: C++, Rust, Go
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
Strong ability to communicate complex security concepts to engineering leadership, product teams, and external stakeholders
Experience performing and leading threat modeling, security architecture reviews, and cryptographic design reviews
Eligible to obtain and maintain active U.S. Secret security clearance

Nice To Haves

Experience with post-quantum cryptography, distributed key generation (DKG), or threshold cryptographic schemes
Background in defense, aerospace, or autonomous systems with exposure to FIPS 140, Common Criteria, or NSA CSfC requirements
Experience designing secure communication protocols for autonomous platforms or mesh networks
Deep knowledge of Linux kernel security, mandatory access controls (SELinux/AppArmor), and OS hardening at scale
Experience building and evolving platform security services consumed by dozens of teams
Familiarity with compliance frameworks (STIGs, NIST 800-53, CMMC) and translating them into engineering controls that don't compromise developer velocity
Publications, patents, or recognized contributions in cryptography or systems security
Experience with Nix build systems and reproducible build pipelines for security-critical software

Responsibilities

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
Lead the design of hardware root-of-trust architectures integrating TPMs, TEEs, HSMs, and secure boot across diverse embedded platforms
Drive the strategy for promoting business-line security implementations into shared, composable platform services
Serve as the senior technical authority for security architecture reviews across the organization, providing definitive guidance on cryptographic design, protocol security, and system hardening
Define security patterns, reference architectures, and engineering standards that enable teams across Anduril to build securely and independently
Mentor and develop senior engineers on the team, raising the bar for security engineering across the organization
Represent Anduril's security engineering capabilities to customers, partners, and auditors when deep technical credibility is required
Evaluate emerging threats, cryptographic standards, and security technologies, driving adoption where they strengthen the platform
