Job description

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.

About the Team

Anduril Cyber is focused on positioning Anduril as a lead provider of capabilities to enable offensive cyber missions. Cyber is a new business line at Anduril, and relies upon our fleet of autonomous vehicles, the Lattice operating system, mesh networks, and other hardware products to engage in cyber operations at the edge. We design and build novel solutions to deploy cyber capabilities in unconventional or difficult to reach environments. The new Lattice for Cyber team will build the core capabilities, experiences, and primitives that allow our Cyber products to operate reliably at scale. This is a founding team working from an unusually blank sheet of paper.

About the Job

As a Software Engineer in Lattice for Cyber, you will build the core capabilities, experiences, and primitives that our offensive Cyber programs rely on. You will solve a wide variety of problems involving networking, autonomy, systems integration, robotics, and more, while making pragmatic engineering tradeoffs along the way. Your efforts will ensure that Anduril products seamlessly work together to achieve a variety of critical outcomes. Clean interfaces, real documentation, and working examples are the product, not chores that come after it. Above all, Anduril engineers on this team are driven by a "Whatever It Takes" mindset — executing in an expedient, scalable, and pragmatic way while keeping the mission top-of-mind and making sound engineering decisions to deliver successful outcomes on-time and with high quality. Not only will you build the software, you’ll have the opportunity to work with the customer’s to deploy it.

What You’ll Do

• Build highly-available and scalable services, data models, and APIs that power our offensive cyber products such as command and control frameworks, autonomous cyber behavior trees, SIGINT analysis tools, and data exfiltration pipelines.
• Integrate best-of-breed Cyber tools and products into Lattice via custom SDKs or white-glove integrations.
• Work directly with program teams and customers as they build real missions on your products.
• Contribute to technical leadership, design clarity, and long-term maintainability across a growing software stack.
• Design distributed software systems that work reliably between the far edge and the enterprise across degraded, intermittent, and contested networks.
• Incorporate AI/LLM-enabled workflow features where they improve analyst or operator effectiveness without compromising system reliability.
• Build SDKs and integrations to allow best-of-breed vendors to incorporate their software and tools into our Lattice Cyber platform.
• Contribute back to the Lattice software platform core, allowing your products to provide value across the entire company.

Required Qualifications

• 8+ years of experience designing, building, and operating production software.
• Strong software engineering experience in one or more of C, C++, Python, Go, Rust, or modern TypeScript/React application development.
• Ability to debug across the full stack, including logs, networking, interfaces, configuration, and hardware/software boundaries.
• Practical experience with Linux and containerized deployment.
• Comfort collaborating with cross-functional engineering teams and translating ambiguous requirements into clean software interfaces.
• Strong written and verbal communication skills for technical reviews and architecture discussions.
• Based in, or willing to relocate to, the Washington, DC or the Orange County, CA metro areas.
• Willingness to travel up to 20% of the time support program teams and customer events.
• US security clearance eligible

Preferred Qualifications

• Hands-on offensive or defensive cyber background.
• Exposure to AI/LLM integration patterns, inference workflows, tool orchestration, or model-assisted application features.
• Front end experience in TypeScript and React. This is a backend leaning role, but we generally work across the stack.
• Track record of technical leadership, productization work, or direct customer interface in complex engineering environments.
• Prior work delivering into air-gapped or otherwise constrained deployment environments.
• An active U.S. Security clearance.
