Spaceflight Software Intern: Embedded & HITL Dev

York Space Systems; Greenwood Village (CO); On-site; USD 30,000 - 47,000; Full time

Job summary

York Space Systems invites a curious Software Engineering Intern to help build software that interacts with real spacecraft hardware. You will work with Flight Software and Test engineers to command, monitor, and validate space vehicles, touching embedded Linux, hardware interfaces, and automated testing in a hands-on environment.

The internship emphasizes problem solving across software and hardware, with exposure to the full engineering loop—from writing code to running it against hardware or

Qualifications

• Experience developing software for embedded systems.
• Experience with C or C++ on Linux.
• Experience debugging software that communicates with physical devices.
• Familiarity with serial, Ethernet, TCP/IP, UDP, CAN, SPI, I2C, or similar interfaces.

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.
• Build tools that command, monitor, configure, and validate spacecraft subsystems.
• Participate in Software-in-the-Loop (SITL) and Hardware-in-the-Loop (HITL) development and testing.
• Connect software to real hardware interfaces, networks, telemetry streams, and subsystem simulators.
• Troubleshoot problems across software, operating systems, networks, and hardware.
• Debug failures using logs, telemetry, command-line tools, debuggers, and test equipment.
• Develop automated tests that exercise spacecraft functionality and verify expected behavior.
• Support York's test-like-you-fly philosophy by helping make test environments behave more like the real vehicle.
• Write and execute unit tests and integration tests.
• Participate in technical design discussions and code reviews.
• Work with systems, software, electrical, and test engineers to turn high-level requirements into working solutions.
• Identify technical risks early and help develop practical solutions.
• Use Git, GitLab, CI/CD, and modern software-development workflows.
• Communicate what worked, what failed, what you learned, and what you want to try next.
• Love space!
