Using MATLAB/Simulink and related tools, you will bridge control system design, software development, and verification while helping teams establish scalable, model-driven engineering practices.\nYou will play a key role in establishing the tools, processes, and infrastructure needed to develop, generate, integrate, and validate production-quality flight software from system and control models. This includes defining model-based development standards, implementing automated code generation pipelines, and integrating generated software with embedded flight systems and SIL/HIL test environments.\nThe ideal candidate has hands-on experience implementing Model-Based Design workflows in aerospace, defense, automotive, or other safety-critical environments. We are looking for an engineer who can take ownership of building these capabilities, work across engineering disciplines, and help drive adoption of model-based development throughout the organization.\nResponsibilities\nDevelop and maintain high-fidelity, 6-DOF aircraft simulation models using MATLAB/Simulink to support vehicle development, pilot training, Monte Carlo analysis, and system verification.\nDevelop, implement, and maintain Model-Based Design workflows using MATLAB, Simulink, and related tools to support simulation development and integration.\nBuild and expand simulation capabilities that integrate aircraft dynamics, sensors, actuators, and flight software.\nEstablish model-based development processes across flight software, GNC, and flight sciences engineering teams, initially focused on simulation with future expansion into control system development.\nDevelop and support Model-in-the-Loop (MIL), Software-in-the-Loop (SIL), and Hardware-in-the-Loop (HIL) verification workflows.\nImplement automated code generation workflows to translate Simulink models into production-quality C/C++ software for simulation and embedded flight systems.\nDefine best practices for model architecture, configuration management, code generation, testing, and verification.\nIntegrate generated software with existing simulation environments, flight software architectures, embedded targets, and hardware interfaces.\nBuild automated testing and continuous integration processes for model-based development.\nCollaborate closely with GNC, flight software, avionics, systems, and test teams to ensure consistency between models, generated code, and deployed systems.\nDebug and resolve issues involving model behavior, generated code, software integration, and system performance.\nSupport requirements traceability, model verification, and validation activities for flight-critical software.\nHelp drive adoption of Model-Based Design practices through technical guidance, documentation, and cross-functional collaboration.\nRequirements:\nBachelor's degree in Aerospace Engineering, Electrical Engineering, Computer Engineering, Computer Science, Mechanical Engineering, or a related field.\n5+ years of experience in Model-Based Design, embedded software development, controls engineering, or related technical fields.\nStrong hands-on experience with MATLAB/Simulink and model-based development workflows.\nExperience using Simulink Coder, Embedded Coder, or similar tools to generate executable C/C++ software from models.\nDemonstrated experience developing, implementing, or improving Model-Based Design workflows in an engineering environment.\nExperience integrating generated code with embedded software or real-time systems.\nProficiency in C/C++ and familiarity with embedded software development practices.\nUnderstanding of control systems, dynamic systems, and software verification methodologies.\nExperience with MIL, SIL, or HIL testing and validation.\nStrong debugging and problem-solving skills across models, generated code, and software interfaces.\nAbility to work across multidisciplinary engineering teams and take ownership of complex technical initiatives.\nPreferred Skills and Experience:\nExperience establishing Model-Based Design processes or infrastructure across multiple engineering teams.\nAdvanced experience with MATLAB/Simulink, Stateflow, Simulink Test, Simulink Coder, and Embedded Coder.\nExperience implementing model-based code generation pipelines for production or flight-critical embedded software.\nFamiliarity with model-based software architecture, reusable model libraries, and modeling standards.\nExperience integrating model-based development workflows into CI/CD pipelines, automated testing, and software configuration management.\nExperience with real-time embedded targets and platforms such as Speedgoat, dSPACE, NI VeriStand, or OPAL-RT.\nExperience developing or integrating flight controls, GNC, avionics, or autonomous systems.\nFamiliarity with aerospace software development standards such as DO-178C and DO-331.\nKnowledge of model verification, code verification, requirements traceability, and software qualification processes.\nExperience with aircraft, UAVs, spacecraft, automotive control systems, or other complex safety-critical platforms.\nStrong ownership mindset with the ability to introduce new development practices, solve ambiguous technical problems, and help engineering teams iterate quickly.","description_format":"text","description_chars":5712,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Defense
