• Experience developing an RTOS or embedded software that runs on an RTOS, with a working understanding of RTOS concepts.
• Experience with C and Python.
• Hands-on integration and test experience at both the system level, including hardware/software integration, and the software level, including testing against high- and low-level requirements.

Preferred Qualifications:

• Master’s degree in Software Engineering or a related engineering discipline.
• Experience developing software to DO-178C DAL A standards.
• Experience with ARM processors and associated system-on-chip (SoC) features.
• Experience with multicore embedded systems, asymmetric multiprocessing, or debugging complex SoC architectures.
• Experience developing device drivers or board support packages (BSPs).
• Familiarity with data transfer interfaces and protocols such as ARINC 429, MIL-STD-1553, and PCIe.
• Experience with boundary value analysis (BVA), structural coverage analysis (SCA), and data and control coupling analysis (DCCA).
• Experience with DO-330 tool qualification.
