## Job description

Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.

About The Role: 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.

Fall: Around 16 weeks (August - December)

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.

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

The hourly rate listed for this internship is intended as a general guideline. Final compensation will be determined based on degree level. Benefits: Time Off: Interns are eligible for 5 days of sick leave and unpaid time off. Office Perks: Weekly paid office lunches and fully stocked breakrooms.

## About Hermeus

## Company Overview
- **One-liner**: Hermeus is an aerospace and defense company building the world’s fastest aircraft through rapid iterative prototyping, targeting high-Mach and hypersonic flight for national security and commercial applications.
- **Entity Type**: Private (Series C, ~$350M raised in latest round)
- **Headquarters**: Hawthorne, California, USA (primary HQ at 3401 Jack Northrop Ave; additional offices in Los Angeles/El Segundo, Atlanta, Jacksonville, and Washington, D.C.)
- **Founded**: 2018
- **Founders**: AJ Piplica, Glenn Case, Skyler Shuford, Michael Smayda

## Core Business
- **Primary industry**: Aviation and Aerospace Component Manufacturing; Defense Technology
- **Target customers**: B2G (primarily U.S. Department of Defense and allied nations), with future potential in commercial high-speed travel
- **Mission**: Build the world’s fastest aircraft by reclaiming the lost art of rapid iterative prototyping, delivering high-speed systems that provide an asymmetric advantage for the nation and its allies.

## Products & Services
- **Quarterhorse Program**: A series of four purpose-built unmanned aircraft, each designed to unlock a specific technical challenge and incrementally de-risk hypersonic technology. The first aircraft flew in 2025, and the company reached supersonic flight just 364 days later—the fastest time from founding to supersonic flight in aviation history.
- **High-Speed Propulsion Systems**: Development of air-breathing engines, including testing at the High Enthalpy Airbreathing Test (HEAT) facility in Jacksonville, FL, using Pratt & Whitney F100 engines as a baseline.
- **Hypersonic Aircraft Platforms**: Future planned vehicles aimed at affordable, reusable hypersonic flight for defense and eventually commercial passengers.

## Market Standing
- **Valuation**: Not publicly disclosed (conflicting reports; PitchBook lists latest Series C at $350M, total funding ~$566M)
- **Key Metric**: Total Funding ~$566M (9 rounds); Annual Revenue estimated at $5.6M (LinkedIn data, likely early-stage).
- **Notable Investors/Partners**: Sam Altman (led Series B), Khosla Ventures (led Seed), United States Air Force ($60M grant), NASA (Non-Equity Assistance), and other defense-focused investors.
- **Growth Signals**: 286 employees (+42% YoY); 122,889 LinkedIn followers (+58.2% yearly); rapid expansion from concept to supersonic flight in under 7 years; multiple open positions across engineering, manufacturing, and operations.

## Competitive Advantages
- **Speed of Iteration**: Hermeus is the fastest company in aviation history to go from founding to supersonic flight (364 days after first flight), using a hardware-rich, test-early approach reminiscent of the Skunk Works era.
- **First-Principles Engineering**: Small, cross-disciplinary teams that own problems end-to-end, enabling rapid decision-making and prototyping.
- **Government & Strategic Relationships**: Deep ties with DoD, USAF, and NASA, providing both funding and clear mission requirements.
- **Facilities & Infrastructure**: Four locations covering design, manufacturing, propulsion testing, and policy engagement, including a 110,000 sq ft facility in Atlanta and a dedicated test site in Jacksonville.

## Strategic Focus
- **Current priorities**: Scaling the Quarterhorse program to achieve hypersonic flight; maturing engine and airframe integration; expanding manufacturing capacity; hiring top engineering and operations talent; deepening partnerships with defense customers.
- **Direction for growth**: Move from unmanned demonstrators to operational hypersonic aircraft for defense, and eventually develop a commercial high-speed air transport capability.

## Why Work Here
- **Culture**: Described as "rapid, relentless iteration" with a "total disregard for what others say can't be done." Emphasizes extreme ownership, stubborn focus, and a small-team, high-impact environment.
- **Remote/Hybrid/Office Policy**: On-site roles required at Hawthorne (LA), Atlanta, Jacksonville, or D.C. (multiple open positions are on-site).
- **Notable Perks**:
  - 100% premium coverage for health, dental, and vision for employees and dependents
  - 3 months paid parental leave (100% pay) plus optional additional unpaid month
