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.
ABOUT THE TEAM
The Simulation Platform team owns the core architecture and infrastructure of Anduril's high-fidelity, multi-domain military mission simulator. It models hundreds of entities--aircraft, ships, submarines, satellites, ground vehicles--moving, sensing, communicating, and engaging across realistic physical environments. The simulator powers training, mission planning, autonomy development, and hardware-in-the-loop testing across Anduril's product portfolio. It connects to live systems, integrates with Anduril's Lattice platform, and runs inside a GUI for interactive scenario authoring. Mission Sim is a large, mature C++20 codebase with an Entity-Component-System architecture, a stable C ABI plugin system, embedded scripting, and a variety of physics-based models. Keeping this system fast, correct, extensible, and pleasant to develop against at scale, with a growing team of model developers is our job.
ABOUT THE ROLE
Platform work is leverage. Every API you design, every millisecond you shave off the frame loop, every rough edge you smooth in the developer experience — it multiplies across every model, every scenario, and every engineer which builds atop Anduril’s mission simulator. You'll work on a genuinely complex system (real-time, multi-domain, deterministic, plugin-extensible) where architectural decisions have concrete, measurable consequences and correctness matters. The simulator is how Anduril tests autonomy before it touches hardware, how operators train on mission scenarios, and how engineers validate that sensors and platforms behave as expected. This platform is what makes that possible at scale.
This role is open to senior engineers and strong mid-career engineers who are ready to own significant pieces of a complex system. If you've spent your career building applications and want to shift toward framework and infrastructure work, this role is for you!
WHAT YOU'LL DO
- Performance and scale — keep the simulation loop fast enough for real-time and faster-than-real-time execution with hundreds of concurrent entities; reasoning about memory layout, cache behavior, and contention as entity counts grow
- Custom Entity-Component-System architecture that underpins the entire simulator: entity lifecycle, component storage, system registration, and the update loop
- Plugin and SDK development: maintain a versioned C ABI, enabling external teams to extend the simulator
- Integration architecture: gRPC services, DIS protocol interoperability, networking messaging, and file recording for playback
- Support domain experts in integrating new and enhancing existing capability models
REQUIRED QUALIFICATIONS
- 3 years of professional experience with C++20 and strong C++ skills; you should be comfortable with templates, move semantics, smart pointers, and the kinds of design decisions that show up in framework code
- Experience designing internal APIs and frameworks that other engineers build on — you care about backwards-compatibility, ergonomics, not just correctness
- Solid understanding of systems programming fundamentals: memory management, shared libraries, ABI stability, linking, and platform-level concerns
- Comfort with linear algebra and applied math
- Familiarity with Linux based C++ development toolchains
- Ability to reason about performance-sensitive code--cache behavior, memory layout, algorithmic complexity
- Clear technical communication and ability to work in a large, shared codebase with architectural decision making that impacts a growing team
- Eligibility to obtain and maintain an active U.S. Government Secret security clearance
PREFERRED QUALIFICATIONS
- 5+ years of professional experience with C++20
- Experience with military simulation, defense modeling & simulation (M&S), or related domains
- Experience with Entity-Component-System architectures or game engine design patterns
- Familiarity with gRPC, DIS (IEEE 1278.1) distributed simulation standard
- Experience with Python/C++ interop (pybind11, embedded interpreters)
- Familiarity with behavior trees or autonomous agent architectures
- Exposure to Nix for reproducible builds
- Experience with numerical simulation, physics modeling, or scientific computing
