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 our Cyber products to operate reliably at scale.

About the Job ABOUT THE JOB

• 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.
