Senior Software Engineer, Backend - SIG

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. 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. Anduril’s family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center.

As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years.

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 Software Engineer, Backend on the Systems Integrity Group (SIG), you will build backend services and APIs that power simulation, digital twin validation, and V&V automation systems. You will develop systems that integrate simulation frameworks, geometric validation services, and 3D visualization data with enterprise systems to verify manufactured output matches engineering intent.

• Design and implement backend services that orchestrate simulation frameworks, digital twin validation workflows, and V&V automation pipelines.
• Develop APIs that expose validation results, geometric comparison data, and simulation outputs to downstream consumers including UE5 visualization, quality systems, and operational dashboards.
• Partner with manufacturing engineers and factory operators to understand production workflows and translate them into backend service requirements.
• Write production-quality code with comprehensive tests, participating in code review and architectural discussions.
• Build backend integration layers that retrieve 3D CAD geometry, as-built scan data, quality measurements, and engineering specifications from PLM, MES, and quality management systems.
• Design and maintain databases optimized for storing simulation results, validation findings, geometric comparison data, and historical V&V records.
• Implement event-driven architectures that trigger validation workflows when manufacturing milestones occur or design changes are released.
• Deploy and operate your systems in factory environments, including edge compute clusters and OT networks.
• Optimize backend performance to support computationally intensive workloads including geometric validation, simulation orchestration, and 3D data processing.
• Build data pipelines that feed real-time production data from the Unified Namespace to digital twin simulations and 3D visualization systems.
• 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.

• 6+ years of experience in a software engineering role building production systems, ideally in a fast-paced environment.
• Strong expertise in backend software development with foundations in distributed systems and API design.
• Strong technical fluency in modern software architectures, APIs, distributed systems, CI/CD, and cloud or edge infrastructure.
• Proficiency in backend programming languages (e.g., Python, Go, Java, Rust).
• Experience with database management systems…
