About The Position

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years. Team Overview 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. Job Description 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. We're also open to hiring talented software engineers with less security-specific experience, provided they have a strong track record building production software at scale, learn fast, and are motivated to go deep on security.

Requirements

6+ years of experience designing and developing production software in large-scale environments (8+ for Staff level)
Proficient in at least one of: C++, Rust, or Go
Strong software engineering fundamentals: you can design, build, and operate complex systems and pick up new domains quickly
Experience working on security for distributed systems, or demonstrated ability and motivation to develop deep security expertise
Ability to work directly with product and engineering teams to translate requirements into working implementations
Comfortable working across multiple problem domains rather than specializing in a single area
Strong communication skills with proven ability to negotiate and reach consensus across teams
Eligible to obtain and maintain active U.S. Secret security clearance

Nice To Haves

Experience or willingness to learn in a subset of the following:
Designing and implementing secure protocols, APIs, or cryptographic systems
Integrating secure hardware (TPM, TEE, HSM)
Operating system security and hardening (Linux)
Securing Kubernetes deployments and container runtimes
Embedded systems or robotics security
Secure cloud architectures (AWS or Azure)
Performing security architecture reviews and threat modeling
Additionally valuable:
Proficient in: TypeScript, React, Python
Experience building shared libraries, SDKs, or platform services consumed by other engineering teams
Knowledge of cryptographic primitives and best practices (key management, certificate lifecycles, secure key storage)
Familiarity with compliance frameworks (STIGs, NIST) and translating requirements into engineering controls
Experience with Nix build systems

Responsibilities

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 platform systems
Implement cryptographic protocols, key management systems, and certificate infrastructure
Work across the technology stack: secure hardware (TPM, TEE), operating systems, container orchestration, and application-layer security
Provide hands-on engineering support to business line teams adopting platform security services
Collaborate with the Security Applications & Tools team on cross-cutting security infrastructure
