Flight Software Engineer - Space Systems (Embedded)

Craig Technologies; Huntsville (AL); On-site; USD 90,000 - 140,000; Full time

Job summary

Craig Technologies is seeking an Embedded Software / Flight Software Engineer to join our Huntsville, AL team, with options for Houston or Merritt Island. You will architect, implement, and verify core flight software for satellites in cislunar and lunar orbits, delivering high-reliability, deterministic code for real-time operations and autonomous fault recovery.

The role emphasizes onboard data handling, robust testing, hardware interfaces, and close collaboration with hardware designers to

Qualifications

• Bachelor’s Degree in Computer Science, Computer Engineering, Physics, or a highly related engineering domain plus 5-10 years of experience in embedded flight systems.
• 5-10 years of direct experience writing high-reliability code utilizing C and C++ in a bare-metal, RTOS, or embedded Linux environment.
• Proven experience in deep hardware/software system integration, low-level debugging, and utilizing hardware test equipment (oscilloscopes, logic analyzers).
• Familiarity with standard serial communications protocols (RS-232, RS-422, RS-485) and standard packetized networking protocols (IP/UDP, IP/TCP).

Responsibilities

• Design, implement, test, and maintain embedded flight software features, device drivers, and structural system improvements.
• Analyze, test, and perform low-level I/O timing and data throughput performance assessments on integrated hardware/software architectures.
• Interface closely with hardware and electronics designers to coordinate seamless software-to-avionics integration and board bring-up activities.
• Draft automated unit, integration, and regression tests to validate flight logic against strict system constraints.
• Coordinate high-level functional testing of features on flat-sats, hardware-in-the-loop (HWIL) setups, and flight-representative simulators.
• Implement autonomous FDIR flight routines to handle radiation-induced hardware resets or bit-flips autonomously.
• Other duties as assigned.
