Our mission: radically accelerate air travel.
The Role
As a Modeling & Simulation Software Engineering Intern, you'll develop simulation code, collaborate with teams, design models, and validate results against flight data.
Summary Generated by Built In
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.

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)

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

What We Do

Hermeus is a startup developing hypersonic aircraft to radically accelerate air travel.

At Mach 5, more than twice the speed of the supersonic Concorde, passengers will be able to cross the Atlantic in 90 minutes.

On the path to hypersonic passenger aircraft, Hermeus is partnering with government agencies including the US Air Force and NASA to develop a series of autonomous aircraft that derisk the technology and solve urgent national security challenges. These products provide the data and confidence necessary to certify, produce, operate, and maintain safe and comfortable commercial aircraft.

Hypersonic aircraft have the potential to create trillions of dollars of new global economic growth per year, unlocking significant resources that can be utilized to solve the world’s greatest problems.

Why Work With Us

We prioritize hardware and people. Cutting-edge technology is only made possible by bringing together a world-class team. At Hermeus, you will be challenged – but also empowered. We encourage calculated risks taking and learning from our mistakes. Iteration is the name of the game.
