Why we read it this way (6)
No work location is specified in the posting. Given the hands-on hardware bring-up and lab work described (oscilloscopes, logic analyzers, bench testing), this role is almost certainly on-site; remote=false is set accordingly, but the CBSA is unknown.
The Basic Qualifications list C, C++, Python, Rust, and 'similar languages' together as a single production-software requirement. C and C++ are called out explicitly for embedded/microcontroller work in the responsibilities, so they are treated as the primary named skills; Python and Rust are captured as alternatives on the C entry to reflect the 'or similar' framing.
Communication protocols (SPI, I2C, UART, CAN, Ethernet, RS-485) are listed as a single 'implement communication interfaces such as…' requirement in the responsibilities section. SPI is used as the primary with the others as alternatives, except Ethernet which is emitted separately as a distinct networking technology.
RTOS, Hardware-in-the-Loop, safety standards (DO-178C, IEC 61508, ISO 26262, DO-254), and CI/CD for embedded systems all appear under the 'Preferred Skills & Experience' heading and are marked accordingly.
The role is ITAR-restricted, requiring US citizenship, permanent residency, refugee, or asylee status — or applicable export authorization. This is not a security clearance gate but is a meaningful eligibility constraint not captured in the clearance field.
No compensation figures are provided in the posting.
