What this job asks for AI summary
This role takes full technical ownership of CR-One, a networked NFC/RFID reader platform used in schools for student ID, transportation, food service, and access programs. The engineer will maintain and extend production firmware written in embedded Rust, own the OTA release lifecycle, support factory provisioning and hardware bring-up, and collaborate with hardware, backend, and manufacturing teams. It suits an experienced embedded systems engineer comfortable with resource-constrained microcontrollers and in-field device fleets.

Why we read it this way (7)
No work location or CBSA is specified in the posting; the role appears to be remote or location-flexible within the US, but this is not stated explicitly — remote=true is inferred from the absence of any location requirement and the nature of the work.
The title says 'Principal' but the requirements describe a strong senior individual contributor with no indication of org-wide technical authority or cross-team architectural governance beyond the CR-One platform; seniority is assessed as Senior.
No compensation range is disclosed.
The posting explicitly states the role is not eligible for visa sponsorship.
Embedded Rust is listed under 'Preferred experience' but is also the primary technology named in the job title and the platform description; it is treated as a hard gate given the title-level framing. All other items in the 'Preferred experience' block are marked preferred.
NFC and RFID appear throughout the responsibilities and required qualifications sections and are treated as hard gates; specific protocol variants (ISO 14443, MIFARE, etc.) appear only under Preferred and are marked accordingly.
SOC 15-1252 (Software Developers) is used because the role primarily involves writing and shipping firmware code; 15-1299 is noted as a runner-up given the specialized embedded/firmware nature of the work.
