Senior Model-Based Design Engineer

Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage. About The Role: We are seeking a highly motivated and experienced Senior Model-Based Design Engineer to help establish and advance Model-Based Design (MBD) capabilities across Hermeus' flight software, GNC, and flight sciences teams. In this role, you will develop and implement Model-Based Design (MBD) workflows supporting key applications, including 6-degree-of-freedom (6-DOF) vehicle simulations, pilot training simulators, Monte Carlo analyses, automated code generation, and system verification. 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. You 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. The 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. Responsibilities • Develop and maintain high-fidelity, 6-DOF aircraft simulation models using MATLAB/Simulink to support vehicle development, pilot training, Monte Carlo analysis, and system verification. • Develop, implement, and maintain Model-Based Design workflows using MATLAB, Simulink, and related tools to support simulation development and integration. • Build and expand simulation capabilities that integrate aircraft dynamics, sensors, actuators, and flight software. • Establish model-based development processes across flight software, GNC, and flight sciences engineering teams, initially focused on simulation with future expansion into control system development. • Develop and support Model-in-the-Loop (MIL), Software-in-the-Loop (SIL), and Hardware-in-the-Loop (HIL) verification workflows. • Implement automated code generation workflows to translate Simulink models into production-quality C/C++ software for simulation and embedded flight systems. • Define best practices for model architecture, configuration management, code generation, testing, and verification. • Integrate generated software with existing simulation environments, flight software architectures, embedded targets, and hardware interfaces. • Build automated testing and continuous integration processes for model-based development. • Collaborate closely with GNC, flight software, avionics, systems, and test teams to ensure consistency between models, generated code, and deployed systems. • Debug and resolve issues involving model behavior, generated code, software integration, and system performance. • Support requirements traceability, model verification, and validation activities for flight-critical software. • Help drive adoption of Model-Based Design practices through technical guidance, documentation, and cross-functional collaboration. Requirements: • Bachelor's degree in Aerospace Engineering, Electrical Engineering, Computer Engineering, Computer Science, Mechanical Engineering, or a related field. • 5+ years of experience in Model-Based Design, embedded software development, controls engineering, or related technical fields. • Strong hands-on experience with MATLAB/Simulink and model-based development workflows. • Experience using Simulink Coder, Embedded Coder, or similar tools to generate executable C/C++ software from models. • Demonstrated experience developing, implementing, or improving Model-Based Design workflows in an engineering environment. • Experience integrating generated code with embedded software or real-time systems. • Proficiency in C/C++ and familiarity with embedded software development practices. • Understanding of control systems, dynamic systems, and software verification methodologies. • Experience with MIL, SIL, or HIL testing and validation. • Strong debugging and problem-solving skills across models, generated code, and software interfaces. • Ability to work across multidisciplinary engineering teams and take ownership of complex technical initiatives. Preferred Skills and Experience: • Experience establishing Model-Based Design processes or infrastructure across multiple engineering teams. • Advanced experience with MATLAB/Simulink, Stateflow, Simulink Test, Simulink Coder, and Embedded Coder. • Experience implementing model-based code generation pipelines for production or flight-critical embedded software. • Familiarity with model-based software architecture, reusable model libraries, and modeling standards. • Experience integrating model-based development workflows into CI/CD pipelines, automated testing, and software configuration management. • Experience with real-time embedded targets and platforms such as Speedgoat, dSPACE, NI VeriStand, or OPAL-RT. • Experience developing or integrating flight controls, GNC, avionics, or autonomous systems. • Familiarity with aerospace software development standards such as DO-178C and DO-331. • Knowledge of model verification, code verification, requirements traceability, and software qualification processes. • Experience with aircraft, UAVs, spacecraft, automotive control systems, or other complex safety-critical platforms. • Strong ownership mindset with the ability to introduce new development practices, solve ambiguous technical problems, and help engineering teams iterate quickly. The salary range listed for this role is intended as a general guideline. Final compensation will be determined based on a variety of factors, including role scope and responsibilities, relevant experience, education and training, key skills, market data, and business needs. At Hermeus, compensation is only one part of our total rewards package. We offer competitive pay, equity, and a range of benefits designed to support our team. Benefits: Health & Wellness: 100% employer-paid healthcare and pet insurance Financial: Competitive pay, stock options, 401(k) retirement plan, and potential year-end bonuses Time Off: Paid parental leave, 12 federal holidays, unlimited PTO for exempt employees, and generous accrued PTO for non-exempt employees Office Perks: Weekly paid office lunches and fully stocked breakrooms   U.S. EXPORT CONTROL COMPLIANCE STATUS  The person hired will have access to information and items subject to U.S. export controls, and therefore, must either be a “U.S. person” as defined by 22 C.F.R. § 120.62 or otherwise eligible for deemed export licensing.
