Sr. Mobile App Developer

About the Product

We build a spiritual wellness app, live on iOS and Android, with a growing base of paying subscribers. It pairs guided content with narrated audio and short daily practices. Small team, real users, no bureaucracy.

We're hiring one developer for a focused three months: clear the maintenance backlog, and roll the app out in seven new languages.

DO NOT APPLY IF YOU DIDN'T BUILD AN APP YOURSELF SO AT LEAST 50% OF THE APP FRONTEND AND BACKEND YOURSELF

The Role

Two mandates, both hands-on. You write the code, you ship it, you watch it in production. You'll work directly with the founder — short feedback loops, decisions in hours not weeks.

1. Stability and backlog

Bug fixes, crash triage, performance, offline and audio playback reliability, dependency and OS-version upgrades. Own the release process end to end: builds, TestFlight, App Store and Play Store submissions, review responses, staged rollouts. Maintain in-app subscriptions and paywalls — entitlements, restore flows, edge cases.

2. Language expansion — seven languages

We supply the translated content ourselves. The full content corpus is already translated (or in progress) in-house. You are not doing translation work. You are building the system that serves it.

Target languages: Spanish, French, Italian, German, Russian, Portuguese, Hebrew.

That means:

• The i18n layer — string externalization, keys, pluralization, locale detection and switching, date/number formats
• Handling text expansion — German and Russian run 30%+ longer than English and will break layouts that were designed for English. Finding and fixing those is a real part of the job.
• The content pipeline — per-locale content queries and graceful fallback when a story or audio file isn't yet available in a language
• Localized audio — multiple voice tracks per locale, caching, fallback
• Per-market store listings, screenshots, metadata, and regional pricing tiers
• Making it possible to add a new language without a code change
• Hebrew is right-to-left. It ships last. RTL experience is a plus, not a requirement — but you should be comfortable learning it and using React Native's built-in RTL support.

Milestones

Scope is milestone-gated, not hours-based.

Week Deliverable 1–3 Backlog triage, crash and performance fixes, i18n layer + string externalization 4–6 Spanish, French, Italian live end-to-end — content, audio, layout 7–9 German, Russian, Portuguese — including layout fixes for text expansion 10 Documentation & handover — setup, architecture, runbook. Store listings and regional pricing shipped. 11–12 Hebrew (RTL), or backlog overflow Requirements

Must have

• 3+ years shipping production mobile apps
• At least one app you personally took through App Store and Play Store review
• Strong React Native / Expo and TypeScript
• Real, shipped i18n experience — you've launched an app in multiple languages and know where it breaks. Not "I've used i18next once."
• Hands-on with mobile subscriptions and IAP (RevenueCat, StoreKit, or Play Billing)
• Experience with a Postgres/REST or BaaS backend (Supabase, Firebase, or similar)
• Tests on real devices before shipping — "works on my machine" isn't done
• Fluent English; disciplined enough to work independently without daily supervision

Nice to have

• RTL / Hebrew or Arabic layout experience
• Audio-heavy app experience — streaming, caching, background playback, lock-screen controls
• Push notifications (APNs, FCM)
• App store review or metadata compliance across markets
• Sensitivity to religious or spiritual content — you should be able to handle it with care, whatever your own background

Terms

• 3-month fixed-term contract, remote, working in full-time capacity
• First month is probationary — 2 weeks' notice either side
• Compensation: [range] for the full term, paid monthly against milestones
• All work product and IP assigned to the company
• Documentation and handover are contractual deliverables, due at week 10
• Extension to an ongoing maintenance retainer available; decided in week 10

To Apply

Send:

1. Links to apps you've shipped — especially anything multilingual
2. A short note on the hardest localization problem you've solved and how you found it
3. GitHub or a code sample, if you can share one
