Senior React Native Engineer

Wirewallet•,

11d•$95,000 - $165,000•Remote

About The Position

Wire Wallet is a self-custodial, multi-chain crypto wallet built in React Native. We give users non-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 behalf within rules the user sets. We're a constrained executor, not a discretionary advisor, and that distinction is core to how we build. We're a small, senior team scaling from hundreds of users toward tens of thousands over the next 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.

Requirements

7–8+ years building and shipping production mobile applications, with significant React Native experience (Expo a strong plus)
Deep TypeScript fluency and a track record of owning complex features end-to-end
Strong fundamentals in async, event-driven architecture, real-time data, and API/webhook/OAuth integration patterns
AI-fluent in your workflow. You actively use AI tools (Claude Code, Cursor, or similar) as part of how you ship, and you're comfortable in a multi-agent development environment where AI agents handle real work alongside human engineers with appropriate human review and oversight.
Product sense — you care how the experience feels, not just whether it works
Self-directed, high-trust operator who owns outcomes in a remote senior role
Comfortable working within regulated, security-sensitive boundaries

Nice To Haves

Web3 or crypto experience: Solana especially, plus DeFi, staking, smart wallets, or account abstraction
Experience designing or shipping agentic / rules-based execution systems
Fintech or brokerage API experience (Alpaca, DriveWealth, Plaid, or similar)
SOC 2 or other compliance-conscious environments
Native module work (iOS/Android) for when Expo's managed surface isn't enough
Experience designing or extending in-house abstraction layers across heterogeneous backends (chains, providers, etc.)

Responsibilities

Own significant surfaces of our React Native app and help set the technical direction as the product scope grows.
Make architecture calls, set patterns others build on, and ship complex features end-to-end.
Work directly with the founder and core engineers in a small team where decisions move fast and your work is visible from day one.
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 abstraction layer.
Build out the agentic layer: user-defined strategies, proposed-transaction flows, and automated execution enforced through a combination of on-chain and off-chain controls across each network and, in time, traditional financial institutions.
Develop push-notification-driven confirmations and the surfaces that let users design and monitor their agents.
Deepen EVM support and bring strategy parity across chains.
Address open architectural questions on the EVM side (account abstraction approach, embedded wallet provider choices).
Layer brokerage, banking, and managed investing into the app through a deeply embedded partner API.
Implement account opening, trading, DCA, managed portfolios, debit card controls, and unified portfolio views that span crypto and TradFi.
Develop cross-cutting systems including event-driven architecture across blockchain events, partner webhooks, and push notifications; unified data layer for portfolio and transaction history; identity and permissions that preserve self-custody and pseudonymity on the crypto side.
Ensure quality, security, and shipping, including App Store submissions, performance, crash and error monitoring, and the discipline that comes with handling user funds.
