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.
