FlutterWho we are
At CoinCROWD, we’re building the next-gen wallet for real-world crypto utility. Our flagship product, CROWD Wallet, is secure, intuitive, gasless, and designed to bring digital currencies into everyday spending from a coffee shop to cross-border payments. CoinCROWD is on a mission to make crypto as easy as UPI and twice as powerful.
We’re more than just a blockchain company, we’re an AI-native, crypto-forward, meme-loving team crafting the future of Web3. If you love solving deep problems at the intersection of blockchain, AI, and user experience, we want to talk to you.
What You’ll Be Doing
As a Flutter Developer at CoinCROWD, you’ll own the front-end experience of CROWD Wallet across mobile (iOS/Android) and potentially desktop/web. You'll collaborate closely with backend, design, and AI teams to craft an experience that feels magical even to non-crypto users.
You will:
- Develop and maintain the CROWD Wallet Flutter app with high performance and beautiful UI/UX.
- Build reusable, scalable widgets and component systems.
- Collaborate with blockchain and backend engineers to connect with smart contracts, APIs, and auth layers like Web3Auth.
- Design intuitive flows for crypto actions like swap, buy/sell, send,recieve, transaction history, etc.
- Work with product + engineering teams to integrate LLM-powered UI assistants, predictive UX, and agentic microfeatures (e.g., a “smart suggest” feature based on wallet activity).
- Optimize for performance, accessibility, and delightful cross-platform UX.
- Push updates through app stores and handle release cycles, CI/CD workflows.
Bonus : What makes this role special
We’re building an AI-native UI. This means:

- In-app agents that help users complete tasks: rebalance portfolio, flag scams, etc.
- Personalized UI that adapts to usage patterns.
What We’re Looking For:
- 5–12 years of experience in mobile development with at least 3+ years in Flutter.
- Strong grasp of Dart, state management (e.g., Provider, Riverpod, BLoC), and clean architecture principles.
- Experience with Flutter animations, custom UI, and platform-specific integrations.
- Bonus: Experience with Firebase, Push Notifications, App Store deployment.
- Experience consuming APIs, especially blockchain/Web3 APIs (Ethers.js, WalletConnect, GraphQL, etc.).
- Familiarity with crypto wallets, token flows, swap UIs, or DeFi interfaces is a big plus.
- Awareness of LLMs/AI—you don’t have to be an expert, but curiosity about agentic workflows, GPT integration, or prompt-driven UX is welcome.
- Self-starter mentality with an eye for pixel perfection and product intuition.
Bonus Points
- You’ve worked on a crypto or fintech app with high-performance needs.
- You’ve experimented with GPT or other AI tools inside your app.
- You’ve used AI to automate your testing or CI/CD pipelines.
- You know the difference between ERC20 and ERC721 and care about UX around both.
- You have a good sense of humor and a healthy meme game.
Why Join CoinCROWD
- Equity-first model: Build real value as we scale.
