Develop and deploy real-time simulation environments for aerospace systems, integrating models and optimizing performance for flight control systems, using MBD and automation tools.
Hermeus is a high-speed aircraft manufacturer focused on the rapid design, build, and test of high-Mach and hypersonic aircraft for the national interest. Working directly with the Department of Defense, Hermeus delivers capabilities that will ensure that our nation, and our allies, maintain an asymmetric advantage over any and all potential adversaries.
We are seeking a highly motivated and experienced Senior Software Simulation Engineer to join Hermeus, a hypersonic aircraft startup company. As a Senior Software Simulation Engineer, you will be responsible for developing and deploying real-time simulation environments that support the design, verification, and validation of aerospace flight control and avionics systems. Leveraging Model-Based Design (MBD) principles, you will use MATLAB/Simulink and automated code generation tools to translate dynamic system models into executable real-time code for Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) testing.
This role bridges the gap between control system design and embedded software implementation, ensuring accurate representation of aircraft dynamics and system behavior under simulated flight conditions. You will collaborate with multidisciplinary teams to integrate models with real-time targets, optimize simulation performance, and contribute to the certification and reliability of flight-critical systems.
Ideal candidates will have a solid understanding of aerospace systems, control theory, and real-time simulation platforms, along with hands-on experience in model-based code generation, HIL development, and test automation within safety-critical environments.
Key Responsibilities
- Configure simulation models for real-time execution and deterministic performance on aerospace-grade SIL/HIL platforms.
- Conduct model validation and correlation against analytical models, flight data, or hardware test results.
- Generate optimized C/C++ code from Simulink models for real-time targets.
- Integrate generated code into real-time simulation environments.
- Implement real-time execution tuning (fixed-step solvers, scheduling, data exchange) to meet aerospace system timing constraints.
- Design and implement HIL simulation testbeds that interface with flight control computers, sensors, actuators, and communication buses.
- Configure I/O mapping and signal conditioning for aerospace interfaces such as ARINC 429, MIL-STD-1553, CAN bus, Ethernet, etc.
- Develop automation scripts for test execution, parameter sweeps, data acquisition, and result analysis.
- Support SIL, PIL, and HIL verification campaigns for flight software and control system algorithms.
- Participate in failure injections, stress testing, and fault-tolerant system validation.
- Analyze computational load and latency to optimize real-time model execution.
- Enhance simulation infrastructure, build scripts, and toolchains for automated model builds and regression testing.
- Contribute to continuous integration (CI/CD) pipelines for model-based development and HIL testing.
- Work closely with systems engineers, controls engineers, and flight software teams to ensure accurate system representation.
- Produce comprehensive documentation of models, interfaces, simulation configurations, and test results.
Required Qualifications:
- Bachelor’s or Master’s degree in Aerospace Engineering, Electrical Engineering, Computer Engineering, or a related technical discipline.
- Expertise in MATLAB, Simulink, Simulink Coder, and/or Embedded Coder.
- Experience with real-time simulation platforms (dSPACE, Speedgoat, OPAL-RT, NI VeriStand, or equivalent).
- Understanding of flight dynamics, control systems, and aircraft system modeling.
- Familiarity with communication protocols (e.g. ARINC 429, MIL-STD-1553, CAN bus, Ethernet).
- Competence in C/C++, Python, or automation scripting for simulation and test automation.
Preferred Experience:
- Knowledge of DO-178C/DO-331 processes for model-based software development and verification.
- Experience with flight control system development or verification.
- Knowledge of sensor/actuator hardware, avionics integration, and real-time operating systems (RTOS).
- Familiarity with model-in-the-loop (MIL), software-in-the-loop (SIL), and processor-in-the-loop (PIL) test environments.
- Exposure to simulation and test automation frameworks in an aerospace certification context.
Soft Skills:
- Strong analytical and problem-solving skills.
- Excellent communication and technical documentation ability.
- Attention to detail and commitment to safety-critical standards.
- Ability to collaborate effectively across multidisciplinary aerospace engineering teams.
- Proactive mindset for continuous improvement in modeling, simulation, and verification workflows.
