Senior Software Engineer; Network Simulation

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.

Anduril Intelligence Systems (AIS) is a lead provider of highly specialized engineering products for Intelligence Community (IC) customers. We work within the IC to understand their requirements and shape concepts of operation. We design, develop, and deliver exquisite capability across their mission set using commercially available and custom hardware and software. We provide critically needed capabilities that address our customers’ most pressing national security requirements.

If you are a Senior Software Engineer with deep expertise in networking, protocols, and system architecture to build and maintain sophisticated simulation environments that enable users to experiment with network operations and security testing in controlled settings. This role focuses on designing, developing, and operating realistic virtual machine environments that accurately emulate systems, networks, and behaviors.

As a specialist in simulation and emulation, you will architect complex network topologies, and build representative system configurations. Your work will require both software engineering excellence and deep technical knowledge of operating systems, network protocols, and the behavioral characteristics of various platforms.

With a "Whatever It Takes" mindset, this position demands strong C/C++ or Python development skills combined with hands‑on experience in network engineering, virtualization technologies, and understanding how systems behave in operational scenarios.

Software Development:

• Write robust code to build simulation frameworks, orchestration tools, and custom system components
• Develop software that controls VM lifecycle management, network configuration, traffic generation, and state management
• Build instrumentation and logging capabilities to capture system and network behavior during exercises
• Create APIs and interfaces that enable users to configure, launch, and interact with simulation environments
• Experience with distributed systems

Simulation Architecture:

• Design and build virtual machine environments that accurately simulate systems for security experimentation, including accurate network stacks, system configurations, and behavioral characteristics
• Create realistic network topologies using virtualization and network emulation technologies to replicate operational environments
• Develop modular, reusable VM templates and network configurations that can be rapidly deployed and customized for different training scenarios
• Implement monitoring and observability solutions to track simulation health and user activity

Networking & Protocol Implementation:

• Implement and configure complex network protocols (TCP/IP, DNS, HTTP/HTTPS, SSH, RDP, SMB, etc.) within simulated environments
• Design network segmentation, routing, and firewall configurations that replicate enterprise networks
• Troubleshoot network connectivity issues and ensure proper packet flow within virtualized network environments
• Build traffic generation and network behavior emulation to create realistic network activity patterns

• Strong engineering background from industry or school, ideally in areas/fields such as Computer Science, Software Engineering, Mathematics, or Physics.
• Experience with C/C++, Go, and other common Object‑Oriented languages – C/C++ strongly preferred.
• Deep networking knowledge including TCP/IP fundamentals, routing, switching, network protocols (DNS,…
