Backend Full Stack Engineer Jobs in Irvine, CA (NOW HIRING)

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: the data infrastructure that makes every machine and sensor visible in real time, the manufacturing execution system (ArsenalOS) that workers and planners use every shift, the scheduling engine that replans production in minutes instead of days, and the AI systems that eliminate manual toil from both the shop floor and business operations.
MDP operates at the boundary between Operational Technology and Information Technology. Our systems live where factory-floor machines, edge compute, and OT networks meet enterprise platforms and cloud infrastructure. We incubate solutions close to the production line, validate them with real operators building real hardware, harden them for reliability and security, and then scale them across multiple sites. The environment is fast, physical, and consequential. When our systems go down, production stops. The output of our work is not a dashboard: it is a ship.
This is not a support function. It is a strategic investment by Anduril in the premise that digitizing the manufacturing lifecycle end-to-end, from engineering definition through scheduling through execution through field feedback, is how Heavy Metal will out-build, out-adapt, and out-scale the traditional defense industrial base. MDP is scaling from a founding team to 70+ engineers across multiple U.S. sites. You will be joining early, working on hard problems with real operational stakes, and shaping how manufacturing software is built at Anduril from the ground up.

As a Staff Full Stack Software Engineer on the ArsenalOS Deployment initiative, you will build the full-stack web applications that power daily planning, work assignment, and team-lead dashboards on the factory floor. You will develop offline-capable, mobile-friendly interfaces that factory operators depend on in network-constrained environments where reliability and usability are non-negotiable.
You will Own Maritime-specific manufacturing software requirements end to end. As well as the build-vs-extend decision for each ask. Today that's centered on shop-floor execution (scheduling capability in our MES); the mandate extends to whatever MES, ERP, and adjacent manufacturing capabilities Maritime needs next. Design, develop, deploy and operate across Maritime's factories.

• Build full-stack web applications for daily production planning, work assignment, and team-lead operational dashboards that drive real-time factory execution.
• Develop offline-capable and mobile-friendly interfaces designed for the factory floor, ensuring operators can work seamlessly in network-constrained or intermittent connectivity environments.
• 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 robust offline-first architectures using service workers, local storage, and background sync to ensure application functionality regardless of network conditions.
• Build responsive, touch-optimized mobile interfaces that work on tablets and mobile devices in harsh manufacturing environments (gloves, low light, vibration).
• Architect and implement data synchronization strategies that handle conflict resolution and maintain data integrity between edge devices and backend systems.
• Deploy and operate your systems in factory environments, including edge compute clusters and OT networks.
• 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 backend engineers, data engineers, factory systems teams, and operations to ensure seamless integration with MES, data pipelines, and enterprise systems.
• Set technical direction and mentor junior engineers on best practices for building resilient, user-centered manufacturing software.

• 8+ years of experience in a software engineering role building production systems, ideally in a fast-paced environment.
• Deep expertise in full-stack web development, with demonstrated mastery of both frontend and backend systems.
• Strong technical fluency in modern software architectures, APIs, distributed systems, CI/CD, and cloud or edge infrastructure.
• Proficiency with web-based technologies including JavaScript/TypeScript, React, Next.js, Node.js, and modern web frameworks.
• Experience building offline-capable web applications using service workers, IndexedDB, local storage, and progressive web app (PWA) patterns.
• Experience building systems that must operate reliably under real-world operational constraints (high availability, low latency, or constrained environments).
• Experience working with large enterprise applications and platforms with high availability requirements.
• 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.

• Experience in manufacturing, industrial, or OT-adjacent domains (MES, SCADA, PLC integration, factory automation, IoT).
• Hands-on experience building mobile-first or offline-capable web applications for network-constrained, industrial, or field environments.
• Experience with data synchronization patterns, conflict resolution strategies, and eventual consistency models in distributed systems.
• Familiarity with frontier AI tooling, AI coding assistants, and AI-enabled software development workflows.
• Experience in hyper-growth startup-like environments, with demonstrated success balancing speed, ambiguity, and long-term system health.
• Familiarity with enterprise systems such as ERP, MES, WMS, or manufacturing planning systems.
• Experience designing UX/UI for non-desk workers, including touch-optimized, rugged device interfaces and accessibility considerations for manufacturing environments.
• Experience in manufacturing industries with hands-on exposure to assembly lines or production environments.
• Understanding of edge computing architectures and deployment patterns for factory floor applications.
• Experience with GraphQL, real-time data subscriptions, or WebSocket-based architectures.
• Eligible to obtain and maintain a U.S. Secret security clearance.
