THE TEAM The Air Defense DevInfra team builds and operates the software infrastructure the Air Defense program runs on. Our engineers are talented and hard-working, motivated to see their work rapidly deployed on the front lines - we support the systems that ship to the Southern border, Iraq, Ukraine, and more.
We own developer productivity, build and release tooling, and the cloud infrastructure beneath it - the systems that let other engineers ship faster, with fewer surprises, and with the evidence their programs require. Work ranges from backend services and data pipelines to CI/CD, reproducible builds, container security tooling, and AWS (GovCloud and commercial) infrastructure. Our customers are other Anduril engineers, release engineering, and defense program stakeholders. YOU SHOULD APPLY IF YOU: * Have experience building backend software or developer tooling that real users depend on, and want to grow that experience on a DevInfra team supporting a high-stakes defense program. * Want to own meaningful pieces of shipped work - backend services, pipelines, tooling, and infrastructure - alongside senior engineers who will give you feedback and context. * Love building platform and infrastructure tooling that enables other software engineers to scale their output. * Enjoy working end-to-end on a problem: writing the Go/Python service, standing up the AWS infrastructure via Terraform, wiring it into CI, and debugging it when it misbehaves in production. * Are curious about the layers you haven't touched yet and ready to learn them on the job. * Are a U.S. Person because of required access to U.S. export controlled information, and are eligible to obtain and maintain an active U.S. Top Secret security clearance. NICE TO HAVE * At least 3+ years working with a variety of programming languages such as Rust, Go, C++, Java, Python, JavaScript/TypeScript, etc. * Professional software development lifecycle experience using tools such as version control, CI/CD systems, etc. * Experience building backend software systems with various data storage and processing requirements. * Experience with industry-standard cloud platforms (AWS, Azure), CI/CD tools, and software infrastructure fundamentals (networking, security, distributed systems). * Experience with modern build and deployment tooling (e.g. NixOS, Terraform). * Ability to quickly understand and navigate complex systems and established code bases. * Familiarity with industry-standard monitoring and logging tools. * A bias toward rapid delivery and iteration. * You've built or invented something: an app, a website, a game, a startup. * Previous experience working in an engineering setting: a startup (or startup-like environment), engineering school, etc. If you've succeeded in a low-structure, high-autonomy environment you'll succeed here. * Exposure to containers, SBOM tooling, or vulnerability scanning (Syft, Grype, Trivy). * Prior work on a platform, devinfra, SRE, or developer-productivity team.
