Flutter 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.

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

CometChat Overview

CometChat is a full-stack conversational platform built to unify every layer of interaction - bringing together real-time conversations (chat, messaging, voice, and video), AI Agents, moderation, notifications, and analytics in one modular, developer-first solution.

We were also recognized on Forbes' 2026 America's Top 500 Startup Employers List - a reflection of the team and culture we've been deliberate about building.

We believe the interface of the future is conversation - not clicks. Every app will soon have an AI layer that's as native as text messaging today. That's why we're building the infrastructure for the world's AI-powered conversations - from human-to-human, to human-to-agent, to multi-party collaboration with AI in the mix.

From AI onboarding assistants that get users productive in minutes, to copilots that perform complex workflows in-app, to intelligent moderators that protect and guide communities in real time - our AI Agent platform makes it all possible.

With CometChat's ready-to-use UI kits, powerful SDKs, and our Full Stack AI Agent Platform, product teams across startups and enterprises can launch safe, scalable, and smart in-app interactions faster than ever.

Why Join Us Now

We're at the tipping point where AI becomes a native part of every conversation. At CometChat, you'll help shape a future where users can talk to their apps as naturally as to a friend - where agents think, reason, act, and collaborate with humans in real time.

You won't just be joining a product team - you'll be building the standard for AI interaction layers: agent-aware UI, intelligent guardrails, rich actions libraries, and multi-party collaboration between people and AI.

If you want to help define how the next billion users will communicate - and push the boundaries of what's possible in real-time, AI-powered engagement - we'd love to work with you.

What we mean by AI-native

AI-native here means you build with agents by default. We expect 100% of the code to be generated via agentic tools (Cursor, Claude Code, and similar), while you own everything that actually matters: problem framing, architecture, tradeoffs, review quality, tests, performance, and security. This is not "vibe coding." The code is generated. The thinking is yours. You should be great at steering agents, validating output, catching subtle issues early, and debugging code you did not manually write.

Why AI-native

Software development is changing permanently, and we are leaning all the way in. You will work in a team that ships fast with agents, where your leverage comes from judgment and systems thinking rather than typing speed. You will get access to whatever AI tools you need (Cursor, Claude Code, or anything else that makes you effective), and the freedom to use them aggressively. If you want to operate at the edge of how modern engineering gets done and level up your output, this role is built for that.

Join us to build where AI meets human connection.
