Software Engineering Intern (Modeling & Simulation) - Spring/Summer 2027 at Hermeus

Seniority: Intern

Hermeus is a venture-backed defense aviation company developing high-speed aircraft through rapid hardware iteration. The Modeling & Simulation Software Engineering Intern will develop performant Julia-based 6DOF software-in-the-loop simulation code, collaborate with flight-related teams, create physics-informed models, and validate simulation results against real-world data.

Responsibilities

• Develop performant simulation code for 6 Degrees of Freedom (6DOF) Software-in-the-Loop (SITL) systems using Julia
• Develop user driven features and focus on scalability of our Monte Carlo simulation
• 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

Qualifications

• 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
• 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](https://www.ecfr.gov/current/title-22/section-120.62) or otherwise eligible for deemed export licensing
