• Implement communications across Ethernet, TCP/UDP, CAN, MIL-STD-1553, MIL-STD-1760, and other tactical interfaces.
• Develop simulators, tools, and test infrastructure for software-in-the-loop, hardware-in-the-loop, and system-level testing.
• Debug integrated issues spanning application software, embedded systems, networks, avionics, sensors, and hardware.
• Support integration, ground testing, flight testing, fielding, and collaboration with government customers, platform partners, operators, and engineering teams.

Requirements

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Aerospace Engineering, or a related technical field.
• 3+ years of professional software engineering experience.
• Strong experience with C++, Rust, Python, Go, C, or similar languages, plus software architecture, APIs, networking, serialization, concurrency, and distributed systems.
