## Job description

**The future of aerospace and defense starts here.** 

Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands. 

**Role Overview**

 As an Embedded Flight Software Intern, you will work alongside software and systems engineers to develop, test, and deploy real-time software for rocket engine controllers and airborne or spaceborne platforms. You will contribute directly to flight-critical code, microcontrollers, communication protocols, and hardware-in-the-loop testing environments.

**Key Responsibilities**

-   Write, test, and maintain high-reliability C/C++ code targeting embedded processors and microcontrollers.
-   Implement and debug low-level hardware communication drivers (CAN, SPI, I2C, UART, Ethernet).
-   Develop unit tests, integration tests, and hardware-in-the-loop (HIL) simulation scripts to validate flight software behavior under fault conditions.
-   Debug hardware and software integration issues using logic analyzers, oscilloscopes, JTAG debuggers, and serial telemetry logs.
-   Participate in software design reviews, static code analysis, and technical documentation.

**Basic Qualifications**

-   Currently pursuing a Bachelor’s or Master’s degree in Computer Engineering, Computer Science, Electrical Engineering, Aerospace Engineering, or a related technical field.
-   Proficiency in C and C++ programming for low-level systems.
-   Strong grasp of computer architecture, memory management, pointers, bitwise manipulation, and data structures.
-   Familiarity with Unix/Linux development environments and Git version control.

**Preferred Qualifications**

-   Hands-on experience with Real-Time Operating Systems (RTOS) such as FreeRTOS.
-   Practical experience on university project teams (e.g., CubeSat, Rocketry, Formula SAE, or Robotics).
-   Experience writing Python scripts for test automation and log parsing.
-   Basic knowledge of control systems, avionics architectures, or flight dynamics.

Colorado law requires us to tell you the base compensation range of this role, which is $30.00/hour, determined by your education, experience, knowledge, skills, and abilities. What we _can’t_ quantify for you are the exciting challenges, supportive team, and amazing culture we enjoy. 

Classification: Full-time Non-Exempt
