We deploy the innovative tools, intelligent models, and streamlined processes that make it possible to evaluate complex autonomous flight algorithms at scale. Our tools are utilized in a broad range of simulation-from mission autonomy simulation to Hardware-in-the-loop, and every layer between. In an era of rapid advancement in Artificial Intelligence, our goal is simple: make AI fly-safely, reliably, and fast.\nAs a Staff Modeling & Simulation Engineer, you will be a pivotal force in engineering Shield AI’s foundational simulation platform for our next-generation VTOL aircraft. You’ll develop our emerging simulation engine and deploy advanced aircraft models in C++ across multiple engineering domains-ranging from mathematical physics to the latest in surrogate machine learning methods. You will also utilize your multiphysics and aeronautical systems knowledge to conduct system performance analysis against test and vendor data to ensure simulation results are valid in operational scenarios, and simulation platforms are both stable and fast.\nWhat you'll do:\nDevelop infrastructure and models in C++ for autonomous aircraft simulation.\nServe as a subject matter expert in modern aerospace and software engineering.\nArchitect deterministic, high-performance simulation software.\nLead verification and validation (V&V) analysis studies on models and model tooling.\nCollaborate tightly across autonomy, embedded, GNC, and test engineering teams to ensure our simulation mirrors real aircraft behavior and mission scenarios.\nContribute to platform-agnostic simulation tooling to accelerate future development efforts.\nTrain and guide junior engineers in modeling and simulation best practices.\nRequired qualifications:\nBS in Computer Science, Aerospace, Robotics, or related field.\n7+ years of experience in simulation software development with C++ competency; exceptional candidates with less experience and demonstrated depth will be considered.\nStrong understanding of rigid-body dynamics, kinematics, and the physics of dynamic systems.\nProven experience developing or integrating simulation systems for robotics, aerospace, and/or other complex dynamic systems (e.g., maritime, space, defense ground systems, or gaming).\nAbility to debug complex build and runtime environments.\nExperience with simulation verification and validation.\nStrong communication skills across software, hardware, and systems disciplines.\nMust be eligible to obtain a Secret Clearance; Secret clearance eligibility requires US Citizenship.\nPreferred qualifications:\nMS or PhD in Computer Science, Aerospace, Robotics, or related field.\nFamiliarity with modern C++ standards (C++20 or later).\nGrasp of real-time and deterministic software design, including multi-threading, synchronization, and memory management. \nExperience with DevOps-integrated simulation workflows, including CI/CD and automated testing environments.\nExperience with Hardware- and Software-in-the-Loop simulation environments, including integration of real hardware into simulation environments.\nExperience with CMake, package management tools (e.g. Conan, Nix), and profiling tools.\nExperience with software testing tools (GTest, etc.)\nWorking knowledge of Python for data analysis, test automation, or simulation orchestration.\nExperience working on autonomous aircraft systems.\nActive Secret or Top Secret Clearance is desired.","description_format":"text","description_chars":3494,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
