Modeling Engineer

Senior Modeling & Simulation Engineer | Autonomous Defence SystemsManhattan Beach / Los Angeles Area, California$140,000 – $200,000 + Pre-IPO Equity + Relocation Assistance + Outstanding BenefitsU.S. Citizenship RequiredAre you a Senior Modeling & Simulation Engineer with experience supporting missile systems, autonomous platforms or advanced defence technologies? Do you enjoy building high-fidelity simulations that influence critical engineering decisions long before hardware reaches the field? Do you want to develop the digital environments that shape the next generation of autonomous defence capability? If so, this opportunity may be the right next step for you.This organisation is developing advanced autonomous aerospace and defence technologies that combine intelligent software, sensing and high-performance vehicles to solve some of the most complex challenges in modern defence. Engineers work in highly collaborative, multidisciplinary teams where technical ownership is encouraged, innovation moves quickly and simulation plays a central role in every major engineering decision. From concept development and system architecture through mission analysis and operational evaluation, you'll help shape technologies that transition rapidly from design into deployment.The Senior Modeling & Simulation Engineer will develop advanced simulation environments and mission-level analyses that support autonomous systems, high-performance aerospace platforms and next-generation defence technologies, directly influencing product strategy, engineering development and mission effectiveness.As the Senior Modeling & Simulation Engineer your responsibilities will includeDeveloping high-fidelity mission-level, physics-based and Six Degree of Freedom (6-DOF) simulation modelsPerforming Monte Carlo analysis, mission effectiveness studies and operational trade-off assessmentsBuilding Python-based modelling, analysis, visualisation and simulation toolsSupporting system architecture, algorithm development and engineering decisions through quantitative analysisPresenting technical recommendations to multidisciplinary engineering teams and senior technical leadershipAs the Senior Modeling & Simulation Engineer you will bringDegree in Aerospace Engineering, Physics, Applied Mathematics or a related disciplineExperience supporting modelling and simulation for autonomous systems, missile systems, aerospace platforms or defence technologiesStrong Python programming and scientific computing capabilityExperience with physics-based modelling, Six Degree of Freedom (6-DOF) simulation, Monte Carlo analysis or mission-level operational analysisExcellent analytical, problem-solving and technical communication skills within multidisciplinary engineering environmentsThe Senior Modeling & Simulation Engineer will play a pivotal role in developing the digital environments that define future autonomous defence capability, influencing engineering decisions from concept through operational deployment. Alongside meaningful pre-IPO equity, comprehensive relocation support and outstanding benefits, this role offers genuine technical ownership, exposure to cutting-edge autonomous technologies and a clear pathway towards Principal Engineer, Technical Fellow or Engineering Manager positions as the organisation continues to grow.All successful applicants will be contacted within two working days.
