## About the Role

7+ years of iOS engineering

Fluency in Swift and Objective-C

Experience connecting iOS apps to backend services

Strong grasp of iOS frameworks, design patterns, and the full mobile lifecycle

A complex client-side system you personally architected and shipped. you can explain every decision, what you chose not to do, and what broke

Shipped real work at startups or small teams

Side projects or apps you've put into the App Store. things you built because you wanted them to exist (the bar is something like our founding iOS engineer's music practice journal app, which has 30,000+ downloads and a 4.9 rating)

Exploratory communication. you think out loud, name tradeoffs, stay low-ego when corrected

Comfort with ambiguity and high autonomy. nobody here is going to assign you work

Passion for craft. you treat UI like art

Core Data, Core Animation, and other Apple frameworks

Cloud message APIs and push notifications

Strong opinions on UI/UX

Performance and memory tuning
