Why we read it this way (7)
The JD requires proficiency in at least two of three technology pairs (Kotlin/Java, JavaScript/TypeScript, Swift/ObjC). All three are listed under Required Qualifications, so all are treated as hard gates on the capability — but the 'at least two of three' framing means a candidate lacking any single pair is not automatically rejected. Each pair is emitted as a single skill with its alternative, reflecting the interchangeable nature within each pair.
iOS and Android are listed together as a required mobile shipping experience; iOS is emitted as the primary with Android as an alternative, reflecting the 'and/or' nature of the requirement.
AWS, Firebase, and other cloud services appear under Preferred Qualifications and are treated accordingly.
SDK/framework development experience also appears under Preferred Qualifications.
The compensation range spans two geographic tiers (Metro 2: $190K–$210K; Metro 3: $170K–$190K). The full national range ($170K–$210K) is reported. Per caller instruction, no metro is inferred for this fully-remote role.
