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?  And then you’ll help build the software that answers those questions.    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   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!    Preferred for the Role  Experience developing software for embedded systems   Experience with C or C++ on Linux   Experience with microcontrollers, Raspberry Pi, BeagleBone, robotics, drones, automotive systems, or similar hardware   Experience debugging software that communicates with physical devices   Familiarity with serial, Ethernet, TCP/IP, UDP, CAN, SPI, I2C, or similar interfaces   Experience with multithreading, inter-process communication, or pub/sub messaging   Experience with Software-in-the-Loop or Hardware-in-the-Loop testing   Experience with automated system-level testing   Familiarity with telemetry, command-and-control systems, or distributed systems   Experience with GitLab CI/CD or other automated build/test systems   Experience with CMake or other C/C++ build systems   Familiarity with Docker or containerized development environments   Experience with debuggers, packet captures, logic analyzers, oscilloscopes, or other debugging tools   Experience with spacecraft, aerospace, robotics, or other safety- or mission-critical systems   Personal projects where you built something that moves, communicates, senses, controls, or interacts with hardware  Familiarity with Python or scripting languages   Interest in spacecraft, aerospace, or safety-critical systems   Experience working in lab or system integration environments   Active Secret Clearance
