Key Responsibilities

• Develop, test, and maintain software for autonomous defense platforms, with a focus on performance, reliability, and scalability.

• Design and implement clean, efficient, and well-tested code in C++, Rust, Python, or C.

• Develop software across the stack, from low-level embedded software and firmware to higher-level autonomy and mission applications.

• Work closely with GNC, embedded, systems, and hardware engineers to integrate software with complex electromechanical systems.

• Optimize software for real-time execution, low-latency performance, and resource-constrained embedded platforms.

• Build simulation, testing, and development infrastructure to accelerate software development and validate system performance.

• Debug and troubleshoot complex software and hardware-software integration issues.

• Develop automated tests and contribute to CI/CD pipelines to improve software quality and development velocity.

• Contribute to software architecture and technical design decisions as systems evolve.

• Identify opportunities to improve system performance, reliability, and developer productivity, and drive solutions from concept through implementation.

• Communicate technical challenges, risks, and tradeoffs clearly across a highly cross-functional engineering team.

Required Qualifications

• Experience implementing a substantial software project, such as a capstone, research project, internship project, student design team, or personal project.

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field.

• Graduating with a bachelor’s degree, master’s degree or PhD by end of 2026 or January 2027

• Proficiency in C++, Rust, Python, or C, with the ability to write clean, well-tested, and efficient code.

Preferred Qualifications

• Experience developing software for autonomous systems, robotics, aerospace, or other complex electromechanical systems..

• Experience with embedded systems, microcontrollers, or RTOS environments.

• Familiarity with GNC, controls, state estimation, sensor fusion, or robotics.

• Experience building simulation environments or software-in-the-loop / hardware-in-the-loop testing infrastructure.

• Experience working with sensors, actuators, communication interfaces, or other hardware interfaces.

• Familiarity with Linux, networking, concurrency, or distributed systems.

• Experience with CI/CD, automated testing, and software development infrastructure.

• Experience working on rocketry, UAVs, robotics, autonomous vehicles, or other student engineering projects.
