Senior React Native Engineer

About Wire WalletWire Wallet is a self-custodial, multi-chain crypto wallet built in React Native. We give usersnon-custodial access to Solana, Ethereum, Base, and Bitcoin, along with DeFi yield, staking,swaps, and smart-wallet automation through on and off chain agentic guardrails. .The thing that makes Wire Wallet different is our agentic layer: users define strategies — DCA,yield optimization, conditional swaps — and our system executes them on the user's behalfwithin rules the user sets. We're a constrained executor, not a discretionary advisor, and thatdistinction is core to how we build.We're a small, senior team scaling from hundreds of users toward tens of thousands over thenext year. Our roadmap includes deepening the agentic layer, expanding multi-chain coverage,and building a bridge into traditional finance — brokerage, banking, and managed investing —through a partner integration. These are foundational hires for that push.The RoleYou'll own significant surfaces of our React Native app and help set the technical direction asthe product scope grows. This is a true senior/staff role: you'll make architecture calls, setpatterns others build on, and ship complex features end-to-end.You'll work directly with the founder and core engineers in a small team where decisions movefast and your work is visible from day one.What You'll Work OnCore wallet experience. Continue refining and extending our existing multi-chain wallet:send/receive flows, swaps (Jupiter, 1inch, SwapKit), staking (Marinade, Jito, Lido,Everstake), liquid staking, DeFi positions, and our in-house UPAP multi-chain abstractionlayer.The agentic layer. Help us build out where Wire Wallet is going: user-defined strategies,proposed-transaction flows, and automated execution enforced through a combination ofon-chain and off-chain controls across each network and, in time, traditional financialinstitutions. Push-notification-driven confirmations and the surfaces that let users designand monitor their agents are part of this too. This is one of the most interesting parts of theproduct and where a lot of forward investment is going.Multi-chain expansion. Deepen EVM support and bring strategy parity across chains.Open architectural questions on the EVM side (account abstraction approach, embeddedwallet provider choices) are still on the table.TradFi convergence (next-up workstream). When we get there, layer brokerage,banking, and managed investing into the app through a deeply embedded partner API.Account opening, trading, DCA, managed portfolios, debit card controls, and unifiedportfolio views that span crypto and TradFi.Cross-cutting systems. Event-driven architecture across blockchain events, partnerwebhooks, and push notifications; unified data layer for portfolio and transaction history;identity and permissions that preserve self-custody and pseudonymity on the crypto side.Quality, security, and shipping. App Store submissions, performance, crash and errormonitoring, and the discipline that comes with handling user funds.Our StackMobile React Native, Expo, TypeScript, Expo Router, ReactState Redux Toolkit, redux-persistWeb3 @solana/web3.js, ethers, smart wallets, Bitcoin signer, UPAP (in-housemulti-chain abstraction)Backend & Services Firebase (auth, Firestore, Crashlytics), REST APIs, webhooks, OAuth, PlaidInfra & Tooling Sentry, Mixpanel, OneSignal, EAS Build, Jest, ESLint/PrettierWhat We're Looking For7–8+ years building and shipping production mobile applications, with significant ReactNative experience (Expo a strong plus)Deep TypeScript fluency and a track record of owning complex features end-to-endStrong fundamentals in async, event-driven architecture, real-time data, andAPI/webhook/OAuth integration patternsAI-fluent in your workflow. You actively use AI tools (Claude Code, Cursor, or similar) aspart of how you ship, and you're comfortable in a multi-agent development environmentwhere AI agents handle real work alongside human engineers with appropriate humanreview and oversight. We use AI heavily and want teammates who lean into it thoughtfully,not around it.Product sense — you care how the experience feels, not just whether it worksSelf-directed, high-trust operator who owns outcomes in a remote senior roleComfortable working within regulated, security-sensitive boundariesUS-based strongly preferredNice to HaveWeb3 or crypto experience: Solana especially, plus DeFi, staking, smart wallets, oraccount abstractionExperience designing or shipping agentic / rules-based execution systemsFintech or brokerage API experience (Alpaca, DriveWealth, Plaid, or similar)SOC 2 or other compliance-conscious environmentsNative module work (iOS/Android) for when Expo's managed surface isn't enoughExperience designing or extending in-house abstraction layers across heterogeneousbackends (chains, providers, etc.)How We WorkSmall senior team, fully remote, fast shipping cadence, high ownership.
