Senior Software Engineer, Simulation Platform

Job description

Job responsibilities

• Model authoring tools — an early effort you will help stand up to extend the Sim frontend with UI for authoring and tuning Mission Sim models.
• Custom Entity-Component-System architecture that underpins the entire simulator: entity lifecycle, component storage, and the update loop
• Plugin and SDK development - maintaining a versioned C ABI, which enables external teams to extend the simulator
• Performance and scale — keeping the simulation loop fast enough for real-time and faster-than-real-time execution with hundreds of concurrent entities;
• Integration architecture — gRPC services, DIS protocol interoperability, networking messaging, and file recording for analysis and playback
• Support domain experts in integrating new and enhancing existing capability models

Job requirements

• 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, with focus on backwards-compatibility and ergonomics
• Solid understanding of systems programming fundamentals: memory management, shared libraries, ABI stability, linking, interfacing with the operating system
• 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 and negotiate architectural decisions that affect a growing team
• Eligibility to obtain and maintain an active U.S. Government Secret security clearance
