Why we read it this way (5)
The role is titled 'Mobile Software Engineer' with no level modifier, so advertised seniority is Unspecified. The 3+ years minimum experience requirement supports a Mid-level classification.
Kotlin and Swift are listed together as an 'and/or' pair under Required Qualifications — one platform is sufficient, so Swift is captured as an alternative to Kotlin rather than a separate hard gate.
React Native is required, but the JD adds 'or another cross-platform mobile development framework' — no specific alternative is named, so common peers (Flutter, Xamarin) would be the implied substitutes; however, since no named alternative is given, alternatives are left empty per the posting's framing.
AWS and GCP appear only under Preferred Qualifications ('cloud platforms such as AWS or GCP'), so they are marked preferred with GCP as an alternative to AWS.
All items under 'Preferred Qualifications' (offline authentication, cloud platforms, connected-device ecosystems, secure credential storage, app publishing, performance profiling) are marked preferred. No compensation was stated in the posting.
