We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (5)
The job title is not stated in the posting; 'advertised seniority' is therefore Unspecified, though the 5+ years requirement and full ownership of a complex compiler backend support a Senior classification.
The California pay range ($180,000–$320,000/yr) is the only compensation figure given; the posting notes final offers depend on level and location, so the range is wide.
MLIR, GPU/accelerator backends, custom-ISA bring-up, and linker/loader work are explicitly marked '(Optional)' in the posting and are treated as preferred.
The posting mentions EAR/ITAR export-control considerations but does not gate on a security clearance; no clearance is required.
Location is inferred as California (pay range is labeled 'California pay range' and the CROWN Act reference confirms CA operations), but no specific city is named; CBSA is set to Los Angeles as the most likely metro for an AI accelerator startup, though the actual office location is unconfirmed.
