Why we read it this way (4)
The job is fully remote within the US; no specific metro is listed. Two pay bands are given: $195,000–$255,000/year for CA, WA, NY, NJ, and CT, and $173,000–$233,000/year for all other US states — the lower floor and higher ceiling are reported here.
Swift and Kotlin appear together as the native mobile boundary ('React Native and native boundaries (Swift/Kotlin)'); Swift is listed as the primary skill with Kotlin as an alternative, though in practice both may be used simultaneously rather than interchangeably.
The posting states 'equivalent practical experience or a Bachelor's degree,' so no degree is hard-required.
The '4+ years' figure is the only explicit experience floor stated; the scope and responsibilities described (architectural ownership, mentoring senior engineers, cross-functional leadership) are consistent with a Senior-level role despite the relatively modest stated minimum.
