## Job description

Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge.

For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles.

Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more.

We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet.

## ABOUT THE ROLE

We are seeking talented engineers to work closely with the broader engineering team for an exciting internship opportunity. This person is passionate about engineering, ready to take ownership over complex challenges, and a strong desire to learn about all things satellites. You will have an opportunity to approach this from a fresh perspective targeting an end result indexed on reliability and efficiency. This will require innovation and creativity to ultimately disrupt and make an impact on the industry.

During the 12-week internship program at Apex, you'll gain hands-on experience and professional growth opportunities. You’ll be assigned a project to give you the opportunity to have real impact. Throughout the project you'll have a dedicated mentor to guide you, while participating in learning sessions to elevate your knowledge of aerospace. Plus, you'll connect with peers and industry professionals during our community events, making this a well-rounded experience to launch your career!

Simulation Software Engineering: Interns will contribute to developing closed-loop spacecraft test platforms, such as six degrees of freedom simulation platform (6DOF), software-in-the-loop (SITL) and hardware-in-the-loop (HITL) and executing simulation testing strategies to validate and verify the performance, functionality, and reliability of satellite systems.

## Requirements

- Graduating in the Fall of 2026 or in the Spring of 2027
- BS or MS in Computer Science, Computer Engineering, Electrical Engineering, Aerospace Engineering, or a related field
