- Perform software integration testing and system-level hardware/software integration testing in embedded RTOS environments.
- Analyze test results, investigate discrepancies, document findings, and collaborate with engineering teams to resolve issues.
- Review traceability between software requirements, test procedures, and verification results.
- Learn and apply client architecture, tools, infrastructure, and engineering processes while contributing to active verification work.
- Manage assigned tasks, communicate progress clearly, and raise technical issues or roadblocks promptly.
Required Qualifications:
- Bachelor’s degree in Software Engineering, Computer Engineering, Electrical Engineering, or a related engineering discipline.
- At least 4 years of relevant software engineering experience in avionics or embedded electronic controls within a safety- or mission-critical environment.
- Experience developing software to DO-178C standards.
- 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.
