Why we read it this way (6)
The posting advertises a Senior-level role but explicitly notes openness to Staff leveling at a higher salary band ($280K–$330K). The extracted seniority reflects the base Senior framing; the Staff track is a stated option, not the primary target.
The salary range of $230,000–$280,000 is for the Senior band; the Staff band ($280,000–$330,000) is mentioned separately as an option.
Apple HealthKit and Google Health Connect are listed together as a single integration requirement; HealthKit is named as the primary with Health Connect as the interchangeable alternative.
Native iOS (Swift/Objective-C) and Android (Kotlin/Java) experience is explicitly described as 'a strong plus' — listed under the stack description as preferred, not a hard gate.
Sentry is cited parenthetically as an example of crash monitoring tooling ('e.g., Sentry for mobile') within the requirements section; treated as a representative required tool rather than a strict singleton gate.
The role is strictly in-person 5 days/week at the San Francisco office — remote is not available.
