Senior Backend Software Engineer (Arsenal 2)

Anduril Industries · Santa Ana, California · $191,000-$254,000 USD Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. Maritime Digital Production (MDP) is the software and digital systems function within Anduril's Heavy Metal division. We build and deploy the full technology stack that powers Anduril's shipbuilding factories. As a Senior Backend Software Engineer on the Systems Integrity Group (SIG) initiative, you will build simulation and digital twin validation frameworks that verify manufactured output matches engineering intent. Responsibilities Build web applications that orchestrate simulation frameworks, digital twin validation, and V&V automation workflows for manufacturing verification. Develop UE5-based 3D visualization interfaces that ingest real-time data from the Unified Namespace and render data-rich, interactive views of factory operations, manufacturing processes, and production systems. Partner with manufacturing engineers and factory operators to understand production workflows and translate them into software requirements. Write production-quality code with comprehensive tests, participating in code review and architectural discussions. Design and implement tooling that verifies manufactured output matches engineering intent by comparing as-built geometry, assembly sequences, and quality measurements against design specifications. Build frontend and backend systems that integrate with simulation frameworks (OMNeT++, SimPy, Gazebo, CARLA) to enable factory co-simulation and "what-if" scenario testing. Develop automated V&V pipelines that run integration tests, validation checks, and compliance verification across design, manufacturing, and operations domains. Deploy and operate your systems in factory environments, including edge compute clusters and OT networks. Architect data pipelines that connect CAD models, PLM data, real-time factory sensors, and simulation results into unified visualization and validation workflows. Build responsive web interfaces for V&V dashboards, test management, requirements traceability, and system-level validation reporting. Leverage AI tooling (coding assistants, automation) in your development workflow and contribute to team engineering practices. Join an on-call rotation supporting production factory systems. Collaborate cross-functionally with simulation engineers, systems architects, backend engineers, and manufacturing teams to ensure seamless integration with MES, PLM, ERP, and enterprise systems. Required Qualifications 6+ years of experience in a software engineering role building production systems, ideally in a fast-paced environment. Deep expertise in web development, with demonstrated mastery of backend systems. Strong technical fluency in modern software architectures, APIs, distributed systems, CI/CD, and cloud or edge infrastructure. Proficiency with backend web-based technologies including JavaScript/TypeScript, Python, Go, etc... Experience with real-time 3D engines (Unreal Engine, Unity) or advanced 3D visualization frameworks (Three.js, Babylon.js, WebGL). Experience building systems that must operate reliably under real-world operational constraints (high availability, low latency, or constrained environments). Strong understanding of 3D graphics, rendering pipelines, and data visualization for complex geometric or spatial data. Excellent written and verbal communication skills, with the ability to collaborate across engineering, manufacturing, and operations teams. Degree in Computer Science, Information Systems, Engineering, or related technical field, or equivalent practical experience. U.S. Person status is required as this position needs to access export controlled data. Preferred Qualifications Experience in manufacturing, industrial, or OT-adjacent domains (MES, SCADA, PLC integration, factory automation, IoT). Hands-on experience with Unreal Engine 5 (or Unit
