Staff Software Engineer

About The Team

ArsenalOS is the digital backbone of Anduril’s hardware enterprise. It connects the full lifecycle, from concept to build to field feedback, into one operating environment built for speed, traceability, autonomy, and continuous improvement. This environment includes not just the software used to design, plan, and execute work, but also the factory-facing infrastructure that connects operators, machines, test systems, and OT networks into the same adaptive Build Chain. It is not a support function, but rather a strategic investment by Anduril that the operating system of the hardware lifecycle is how we win. It will be one of the mechanisms by which Anduril out-builds, out-adapts, and out-scales the traditional defense industrial base.

About The Job

We are looking for a Staff Software Engineer to join ArsenalOS, the digital backbone of Anduril's hardware enterprise from design to sustainment. You'll architect the distributed systems within our Manufacturing (Production Solutions) team in Forge MES (Manufacturing Execution System) that orchestrate Anduril's production operations—work order management, scheduling, material flow, and capacity planning—turning factories into adaptive, software-defined production networks. This isn't about digitizing existing processes. It's about building the technical foundation that makes Anduril's hardware enterprise more adaptive as it scales, not less. Your impact will span beyond the immediate team. You'll serve as a technical bridge between Manufacturing and our Platform/Foundations organization, shaping infrastructure that meets production-scale demands while driving adoption of platform capabilities. You'll represent manufacturing in broader architectural decisions, ensuring production requirements influence the systems that connect design changes to shop floor execution. Your decisions will determine whether Anduril can absorb more manufacturing complexity without slowing down—and whether we out-build the traditional defense industrial base.

Required Qualifications

• 12+ years of experience in a software engineering role building products in fast-paced environments
• Proven ability to influence technical direction across teams - drive architectural consensus, build alignment, and lead technical initiatives beyond a single team
• Experience working with large enterprise applications and platforms with high availability requirements
• Strong full-stack capabilities with expertise in modern web technologies - JavaScript/TypeScript, React, and web frameworks (Next.js, Remix, etc.)
• Systems thinking and domain translation - ability to understand manufacturing operations requirements and design scalable technical architectures that enable production workflows at enterprise scale
• Excellent communication skills, able to influence stakeholders, translate ambiguous manufacturing requirements and build cross-team alignment
• U.S. Person status is required as this position needs to access export controlled data

Preferred Qualifications

• Experience in hyper growth startup-like environments. Demonstrated successes in scaling and maturing software development processes, team culture and methods, and ability to balance short-term and long-term trade offs
• Experience with manufacturing execution systems (MES), enterprise resource planning (ERP), production scheduling systems, work order management, or supply chain management platforms
• Experience in defense, autonomy, robotics, or mission-critical systems (helpful but not required)
• Experience with AI/LLM integration - leveraging state-of-the-art models and agentic tooling in production software development
