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.

• Experience with one or more of the following languages: Rust, C++, Go, Python, Haskell
• Eligible to obtain and maintain an active U.S. Secret security clearance

Preferred Qualifications

• Experience with managing cloud computing resources (eg: AWS)
• Experience with modern build and deployment tooling, and continuous integration (e.g. NixOS, Terraform)
• Experience designing complex software systems, and iterating upon designs via a technical design review process
• Familiarity with industry standard monitoring, logging, and data management tools and best practices
• A bias towards rapid delivery and iteration
