Why we read it this way (7)
The job title is 'Software Engineer' / 'Software Development Engineer' with no seniority modifier; the minimum qualifications gate only on 3+ years of professional software development experience, which maps to a Mid-level role despite the architecturally ambitious scope described in the responsibilities.
The role's responsibilities are heavily data-platform and lakehouse-oriented (S3 lakehouse, OLAP analytics, vector databases, federated queries, embeddings), making 15-1243 Database Architects a plausible runner-up, but the basic qualifications frame this as a general software engineering role building cloud services and APIs.
No work location is specified in the posting. The export control clause (U.S. citizen/national, permanent resident, refugee/asylee) implies a US-based role, but no city, state, or remote status is stated — CBSA and state are left blank.
AWS technologies are prominently featured in the responsibilities narrative but appear only there, not in the required or preferred qualifications sections; they are marked as preferred accordingly. Similarly, S3, OLAP, vector databases, and other data-platform technologies appear only in the responsibilities/narrative sections.
The preferred qualifications mention a Bachelor's degree in computer science 'or equivalent,' so no minimum degree is hard-required.
Note that 'software development' and 'system design' are listed as required skills here only to represent the two explicit experience gates in the Basic Qualifications (3+ years each); no specific named technology is hard-gated in the qualifications sections.
Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): software development, system design.
