Senior Software Engineer, Platform Security

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 OverviewThe 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 DescriptionWe'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.Key ResponsibilitiesDesign and implement security features and services for business line products — including custom solutions when platform capabilities don't yet existIdentify patterns across business line implementations and promote them into shared, composable platform security servicesBuild tooling, libraries, and reference implementations that enable engineering teams to adopt secure patterns independentlyLead security architecture reviews and threat modeling for business line and platform systemsImplement cryptographic protocols, key management systems, and certificate infrastructureWork across the technology stack: secure hardware (TPM, TEE), operating systems, container orchestration, and application-layer securityProvide hands-on engineering support to business line teams adopting platform security servicesCollaborate with the Security Applications & Tools team on cross-cutting security infrastructureRequired Qualifications6+ 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 GoStrong software engineering fundamentals: you can design, build, and operate complex systems and pick up new domains quicklyExperience working on security for distributed systems, or demonstrated ability and motivation to develop deep security expertiseAbility to work directly with product and engineering teams to translate requirements into working implementationsComfortable working across multiple problem domains rather than specializing in a single areaStrong communication skills with proven ability to negotiate and reach consensus across teamsEligible to obtain and maintain active U.S. Secret security clearancePreferred QualificationsExperience or willingness to learn in a subset of the following:Designing and implementing secure protocols, APIs, or cryptographic systemsIntegrating secure hardware (TPM, TEE, HSM)Operating system security and hardening (Linux)Securing Kubernetes deployments and container runtimesEmbedded systems or robotics securitySecure cloud architectures (AWS or Azure)Performing security architecture reviews and threat modelingAdditionally valuable:Proficient in: TypeScript, React, PythonExperience building shared libraries, SDKs, or platform services consumed by other engineering teamsKnowledge of cryptographic primitives and best practices (key management, certificate lifecycles, secure key storage)Familiarity with compliance frameworks (STIGs, NIST) and translating requirements into engineering controlsExperience with Nix build systemsUS Salary Range$191,000—$253,000 USDThe salary range for this role is an estimate based on a wide range of compensation factors, inclusive of base salary only.
