Psiphon

Psiphon is a VPN app used by millions of people to access the open internet in regions where it is restricted. Small team. Building the next-gen client app in Flutter (iOS, Android, macOS, Windows) and needs someone who can work across both iOS native and Flutter (roughly 65% Flutter, 35% iOS native in Swift). Mentorship from a senior iOS specialist for deeper networking work. Day-to-day includes feature development in Flutter, iOS platform integration (subscriptions, permissions, App Store), and occasionally deep work into network extensions and packet tunnel providers. Small team (~3-4 core devs) with high ownership and low ceremony. Looking for strong Swift experience beyond UIKit/SwiftUI, comfort with the iOS ecosystem (App Store process, provisioning, StoreKit), and willingness to context-switch between Swift and Dart in the same day. Flutter is a strong plus but not required if frameworks can be picked up quickly.
