Description

Hermeus is a venture capital-backed aerospace and defense technology company. The business is focused on building high-speed products that sustainably deliver asymmetric advantage to the Department of Defense and allied partners. Utilizing an iterative development approach to aircraft, Hermeus’ high-Mach and hypersonic aircraft aim to deliver capabilities at a pace not seen in the U.S. since the 1950s. As a Modeling & Simulation Software Engineering Intern you will work with the software team to develop performant modeling and simulation code for our 6DOF SITL simulation using Julia. You'll Interface with the Flight Software, HMI, and Flight Sciences teams to meet stakeholder needs and ensure accurate results. Your work will involve creating hardware/physics informed software models and validate results with real data. Spring: around 12-16 weeks (January - April) Summer: around 10 weeks (May - August) \n Responsibilities: Develop performant simulation code for 6 Degrees of Freedom (6DOF) Software-in-the-Loop (SITL) systems using Julia. Collaborate with cross-functional teams including Flight Software, Human-Machine Interface (HMI), and Flight Sciences to align simulation outputs with stakeholder requirements. Design and implement physics-informed models that accurately represent hardware behavior and system dynamics. Validate simulation accuracy by comparing model outputs with real-world flight data and refining models accordingly. Optimize simulation performance to ensure real-time execution and scalability across different test environments. Participate in code reviews and testing cycles to maintain high software quality and reliability. Document modeling assumptions, validation results, and integration workflows for internal knowledge sharing and future development. Minimum Requirements: Pursuing a degree in Computer Science, Aerospace Engineering, Electrical Engineering, Applied Mathematics, or a related technical field. Proficiency in Julia or strong experience with scientific computing languages such as Python, MATLAB, or C++. Understanding of 6DOF dynamics and simulation principles, especially in aerospace or robotics contexts. Familiarity with modeling physical systems, including hardware-in-the-loop or physics-informed simulation techniques. Experience with data validation and analysis, including comparing simulation outputs to real-world data. Strong understanding of engineering first principles Demonstrated ability to work within cross-functional teams Enthusiasm for aviation and Hermeus' mission Excellent written and verbal communication skills GPA of 3.0 or above \n $25 - $33 an hour The salary information provided is a general guideline only. Hermeus takes various factors into account, including, but not limited to, the position's scope and responsibilities, the candidate's professional background, education and training, essential skills, and market and business considerations, when presenting a job offer. \n 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.
