Zan - Zari Group

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.

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

What we're building

We're a small studio shipping several products across mobile and web: a live React Native / Expo subscription app on iOS and Android, an AI-powered platform for creators, a sponsorship-intelligence platform, and more in the pipeline. You'll work across this portfolio — full-stack, mobile and web — taking over and extending existing production code rather than building from scratch.

About the role

Your immediate focus is two things: language expansion of our mobile app, and integration work on one of our creator platforms (frontend and backend are built — we need the integrations wired up). Over time you'll contribute across the other products as they evolve. This is a full-stack role: solid React Native / Expo on the mobile side, plus backend and third-party integration work on the web platform.

We're looking for someone earlier in their career but genuinely capable: past the "still learning to ship" stage, hungry to prove themselves, and reliable.

What you'll do

• Add multiple new languages to our mobile app (including Hebrew, which is right-to-left), making sure every screen's layout, alignment and text adapt correctly.
• Fix related UI/responsiveness issues and ship updates to the App Store and Play Store.
• Complete integrations on top of an existing frontend/backend — e.g. Stripe Connect payouts, the AI/LLM content-processing flow, and related REST APIs.
• Full-stack support across the product portfolio (Supabase, Node.js, server-side logic, internal tools) as needed.

Must have

• 2+ years building production mobile apps with React Native + Expo, with at least one app you've shipped to the App Store and/or Play Store.
• A Mac (required to build and ship iOS), plus an iPhone and an Android device or emulator for testing.
• Hands-on App Store Connect / TestFlight and Google Play release experience.
• Strong JavaScript / TypeScript; comfortable with REST APIs and Supabase or Firebase.
• Comfortable with third-party API and payment integration (Stripe). Stripe Connect is a strong plus.
• App localization / i18n experience (externalising strings, handling languages where text runs longer). RTL/Hebrew is a plus, but solid i18n fundamentals matter more — RTL is learnable with React Native's built-in support.
• Tests own work on real devices before shipping; reliable, detail-oriented; communicates clearly in English and flags blockers early.

Nice to have

• Stripe Connect (marketplace payouts), AI/LLM API integration, transcription/vision pipelines.
• Push notifications (FCM/APNs), RevenueCat or in-app subscriptions, CI/CD for mobile.

How we work

• Clear written requirements and acceptance criteria before you start.
• "Done" means tested on a real device with proof (a short recording or screenshots) — not just "works on my machine."
• Only build what's agreed; propose before adding or changing scope. Never delete production/client data without sign-off.
• Short daily update: what's done (with proof), what's next, and any blockers.

Logistics

Fully remote, open to developers in India. You'll work across several products, so variety and range matter. We pay fairly for solid mid-level work, with real room to grow in scope and pay as the portfolio expands.
