Why we read it this way (6)
No specific location is stated in the posting beyond 'US'; the CBSA and state fields are left blank. The compensation range ($114,600–$234,600/yr) is noted as US-wide and varies by location.
The title is not given in the posting; Oracle's internal level 'IC4' is referenced, which typically maps to a Senior individual-contributor band — seniority is assessed as Senior accordingly.
The role blends software development (building scalable distributed systems, writing IaC and automation) with cloud infrastructure operations (incident response, compliance, change management). Software development is the primary day-to-day work, but 15-1244 is noted as a plausible runner-up given the operational and infrastructure emphasis.
No specific programming languages, cloud providers, or named tooling (e.g. Kubernetes, Kafka, Terraform) are called out in the JD; skills are extracted at the capability level as described. The IaC skill lists common substitutes since no specific tool is named.
No degree requirement is stated anywhere in the posting.
Ignored 3 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): load shedding / throttling / rate limiting, distributed state management, performance and load testing.
