Why we read it this way (8)
The posting carries the title 'Principal Software Developer' and Oracle's internal career level 'IC4', which at Oracle typically corresponds to a senior individual contributor — not an org-wide principal authority. The actual requirements (8+ years, team-level scope, no org-wide mandate) support a Senior band; the advertised title is reported separately.
Programming language requirement lists Java, Python, Go, and C++ as interchangeable options ('or a comparable language'); Java is used as the primary with the others captured as alternatives.
Generative AI, LLMs, RAG, and AI agents are listed together in the required qualifications section and are treated as hard gates; they are split into separate skills reflecting distinct capabilities.
Graph databases, vector search, event streaming, and time-series data appear under the required qualifications with the word 'Familiarity with', which signals a softer gate — listed as preferred accordingly.
LangGraph, LangChain, LlamaIndex, Semantic Kernel, and OCI Generative AI Agents appear under Preferred Qualifications; LangGraph is the primary with the others as alternatives. OCI Generative AI Agents is omitted as a separate skill since it is a sub-feature of OCI already captured.
No specific work location or metro is stated in the posting beyond 'US'; CBSA fields are left blank. The role does not appear to be explicitly remote.
Compensation is stated as a broad US range ($114,600–$234,600/year) with eligibility for bonus and equity noted but not quantified.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): cloud architecture.
