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
