Build the mobile experience that makes Usual feel like a neobank — not a DeFi app.

You will own the mobile app end-to-end: from wallet connection flows and transaction signing to real-time balance displays and cross-chain account views.

The product you build will be the first thing most users touch. It must be fast, reliable, secure, and correct when handling real money.
‍

Core Responsibilities
‍

1. Mobile App Development

• Build and maintain a cross-platform React Native app (iOS and Android) in TypeScript.
• Translate Figma designs into pixel-accurate, performant UI components.
• Manage App Store and Google Play release pipelines, including versioning and review cycles.
• Optimize rendering performance, bundle size, and startup time, especially for low-end devices.
• Implement or assist with deep linking and push notification flows.

2. Web3 and Wallet Integration

• Integrate in-app wallet generation and linking flows using Privy for authentication.
• Configure the client for gasless transactions using ERC7702 and ERC4337 account abstraction.
• Handle the full EVM transaction lifecycle: crafting, simulating, gas estimating, signing, broadcasting, confirming, and failure recovery.
• Interact securely with Usual and third-party smart contracts, with proper slippage controls, MEV protection, and least-privilege approvals.
• Read and interpret Solidity contracts to understand interfaces, data structures, and events without relying on the smart contract team.

3. Data and State Management

• Consume on-chain data efficiently using viem and wagmi while optimizing RPC usage.
• Query existing Subgraphs via The Graph and help define requirements for new ones.
• Implement real-time responsiveness for balances, yields, and transaction history.
• Manage local application state across products, chains, sessions, and wallets.
• Collaborate with backend teams on APIs to persist user data where required.

4. UX Reliability and Edge Cases

• Implement optimistic UI patterns while safely handling stuck transactions, reverts, and delays.
• Handle wallet switching, disconnection, and reconnection with clear user feedback.
• Support seamless multi-chain interactions across Ethereum, Arbitrum, Base, and BNB.
• Ensure correct app behaviour during RPC or Subgraph lag and network degradation.
• Write unit and integration tests for core financial flows such as deposits, withdrawals, and yield claims.

5. Observability and Quality

• Integrate crash reporting and performance monitoring tools (e.g., Sentry).
• Define and track mobile-specific SLAs, including launch time, data freshness, and failure rates.
• Maintain internal documentation for component architecture and key user flows.
• Participate in code reviews, focusing on security and correctness for financial operations.
  ‍

Expected Outcomes

• A production-grade mobile app shipped and maintained on both App Store and Google Play.
• Reliable account-abstracted Web3 transaction flows across all supported chains.
• Real-time account views with accurate balances, yields, and transaction history.
• Zero critical regressions or security incidents affecting financial flows.
• A documented component library and flow diagrams stored in the internal knowledge base.
  ‍

Candidate Profile

Must Have

• 5+ years of mobile development experience, including 3+ years with React Native in TypeScript.

• Experience shipping apps to the App Store and Google Play, including handling review processes.
• Experience building complex smart contract interactions, such as multi-hop swaps or transaction bundling.
• Strong understanding of the EVM transaction lifecycle (signing, gas, nonce management, failure modes).
• Comfortable reading Solidity contracts to understand what data to query and how.

Nice to Have

• Experience with ERC7702 or ERC4337 account abstraction for gas sponsorship.
• Experience working at a DeFi protocol, stablecoin platform, or consumer fintech app.
• Native iOS (Swift) or Android (Kotlin) development experience alongside React Native.
• Background in financial products where correctness and uptime are critical.
• Experience querying Subgraphs via The Graph client-side.
• Experience with async data fetching patterns such as TanStack Query.
• Experience with state management at scale (Zustand, Redux Toolkit, or similar).
