• Deep knowledge of Apple’s Human Interface Guidelines, App Store Review Guidelines, privacy manifests and App Store Connect.
• Adaptive layouts across iPhone sizes and form factors, including iPhone Duo and iOS 27 multitasking.
• Push notifications (APNs), deep links, background tasks, Keychain and authentication.
• Networking with REST and real-time APIs. Supabase or Postgres experience is a plus.

• Testing with XCTest or Swift Testing.
• Excellent written and spoken English, and 8 hours a day during US Eastern business hours.

Job functions

You’ll build a native iOS app operators use all day: approving guest requests, checking arrivals, answering messages and watching revenue. It should feel like Apple made it.

What you’ll do

• Architect and build the HostOp iOS app in Swift and SwiftUI, on top of our existing APIs.
• Turn Figma designs into polished screens that follow Apple’s Human Interface Guidelines.
• Make every screen adapt across iPhones, from the largest Pro Max to the foldable iPhone Duo, with Dynamic Type, Dark Mode and orientation changes.
• Build the Apple-native features: push notifications, widgets, Live Activities, App Intents, Face ID and Apple Wallet passes.
• Own the App Store pipeline: signing, TestFlight, App Store Connect, privacy labels, review guidelines and releases.
• Set up crash reporting, analytics and CI/CD with Xcode Cloud or Fastlane.
• Keep the app fast, smooth and live-updating, profiled with Instruments.
• Partner with our designers on iOS patterns and with our engineers on the APIs the app needs.
• Help plan Android as a later, separate release.

First 90 days

1. Days 1–30: learn the product, set the app architecture, ship an internal TestFlight build.
2. Days 31–60: core flows working end to end, push notifications live, beta with real operators.
3. Days 61–90: v1 submitted to the App Store.

How to apply

1. Links to iOS apps you shipped to the App Store and what you built in each.
2. A 3-minute Loom walking through one app’s architecture and the hardest problem you solved.
3. How you’d make one screen work on both the largest Pro Max and iPhone Duo.

Shortlisted candidates do a paid technical task.

HostOp is the AI operating system for short-term rental operators with 10 to 500 listings. One platform runs guest check-in, ID verification, damage waivers, upsells, payments and financials, with AI guest messaging next. It’s live with paying operators.

We’re founder-led and bootstrapped, built by a founder who scaled his own rental business to 400+ units. Our web platform runs on Next.js and TypeScript with a Supabase backend.

Now we’re building the HostOp iOS app, natively in Swift, iOS first. You’ll be our first mobile engineer and own it end to end: architecture, build, App Store release and everything after. Our design studio delivers every screen in Figma, and you’ll work with our engineers across Latin America and directly with the founder.
