Job description

York Space Systems is looking for a curious, hands-on Software Engineering Intern who wants to build software that interacts with real spacecraft hardware.

This is not a traditional web-development internship.You'll work alongside Flight Software and Spacecraft Integration & Test engineers to develop, debug, and test software used to command, monitor, and validate space vehicles. Your work may touch embedded Linux systems, spacecraft interfaces, automated test infrastructure, hardware-in-the-loop environments, networking, telemetry, and the tools engineers use to prove a vehicle is ready for flight.

You'll get exposure to the full engineering loop: write code, run it against real or simulated spacecraft hardware, break things safely, debug what happened, improve the software, and run it again.

The ideal candidate enjoys figuring out how things work, isn't afraid of a Linux terminal, likes both software and hardware, and gets excited when their code causes something in the physical world to happen.

Why this internship is different

You won't spend the summer making buttons slightly more rounded.

You'll work on problems like:

Why did this process crash? Why did that packet disappear? Why isn't this device responding? What happens if we restart this service? Did the spacecraft produce the telemetry we expected? Can we automate this test? Can we make this failure happen again?

Key Responsibilities

• Develop and test software used to support spacecraft flight software, vehicle integration, and automated testing
• Write Python, C/C++, Bash, or other software that interacts with embedded systems and spacecraft hardware
• Develop software and interfaces running in embedded Linux environments
