• Build tools, automated tests, and simulation environments that accelerate software development and system validation.
• Troubleshoot and debug complex software and hardware-software interactions.
• Optimize software for performance, latency, reliability, memory usage, and computational efficiency.
• Participate in code reviews, architecture discussions, technical documentation, and continuous integration processes.
• Support system integration, ground testing, flight testing, and field operations.
• Identify technical risks and proactively develop solutions that improve system performance and reliability.

• Bachelor’s, master’s, or doctoral degree in Computer Science, Computer Engineering, Electrical Engineering, Aerospace Engineering, Robotics, or a related technical field.
• Graduating with a bachelor’s, master’s, or doctoral degree by summer 2027.
• Software development experience gained through internships, research, academic projects, student teams, open-source contributions, or professional roles.
• Proficiency in at least one programming language, such as C, C++, Rust, or Python.
• Experience designing, building, testing, and debugging a meaningful software project.
• Understanding of core computer science concepts, including data structures, algorithms, software architecture, and version control.
• Ability to work effectively across engineering disciplines in a fast-paced, hardware-focused environment.
• Ability to work on-site in Huntington Beach, California.

• Experience with embedded systems, firmware, microcontrollers, or real-time operating systems.
• Familiarity with Linux, networking, multithreading, concurrency, or distributed systems.
