## About the Role

A CS degree or equivalent practical experience, and 1+ year of full-time professional experience building iOS apps in Swift.

At least one app you helped ship to the App Store, from work or your own project, that you can walk us through end to end.

Solid Swift and SwiftUI fundamentals: you can write, test and debug a feature on your own, with unit and UI tests as part of how you ship.

AI-native development: you build with AI coding agents (Claude Code, Cursor, Copilot agent mode or similar) every day, and can show how you plan, direct, review and test what they write. You can explain every line you ship, and you keep plans and docs current, so teammates and agents work from the same context.

Willingness to write and learn Kotlin, Kotlin Multiplatform and Compose Multiplatform. Many of our features live in shared code.

Based in the Los Angeles area and able to work from our office 3 days a week.

Nice to have (not required)

Personal apps, open source or hackathon projects you can show us.

App extensions or system frameworks: content blockers, Network Extension, widgets or similar.

Any Kotlin, Kotlin Multiplatform or Compose Multiplatform experience.

## Description

We build consumer privacy and security apps for iOS and Android. Our apps run on Kotlin Multiplatform. On iOS, Swift and SwiftUI drive the app's navigation and overall experience, plus the parts that depend most on Apple's platform: system extensions, StoreKit and deep OS integration. You'll build that iOS depth with us and work in shared Kotlin too. You'll take features from idea to the App Store: plan, build, test, ship and support them in production.

You'll join a small, hands-on team where engineers own features across both platforms. You'll work directly with our head of mobile, who sets the architecture, still writes code and mentors the team. You'll have a real say in technical decisions, grow your skills across iOS, Android and Kotlin Multiplatform, and take on more ownership as the platform grows.

What you'll do

Build privacy and security features with Apple's system extensions, such as content blocking and network filtering.

Build subscriptions and accounts with StoreKit 2.

Write shared Kotlin alongside Swift, and review both iOS and Android code.

Own your features in production: TestFlight, App Store review, crash and log triage, performance and battery tuning with Instruments, fixes.

Work with AI coding agents every day: plan the work, keep each step small and tested, review what the agent writes.

Write a short plan before you build and keep it current as the work changes.
