Evolve our mature non-custodial crypto wallet by adding new capabilities.
Own the core of the app — send/receive, balances, transaction history, swap/bridge, on-ramp — and lead its product extensions, including the crypto card and IBAN experience: payments, subscriptions, physical card integration, and onboarding additional card providers across new geographies.
Own features end-to-end — from planning and architectural design to implementation, testing, production monitoring, and iterative improvement based on real user feedback.
Collaborate closely with Product and Design teams to deeply understand user needs, shape product direction, and co-create solutions that deliver tangible value.
Partner with QA and backend engineers to ensure strong quality control through clear documentation, reproducible testing flows, and knowledge sharing.
Take part in a shared on-call rotation — roughly one week a month.
Communicate clearly and proactively by producing technical documentation and guides for internal teams, and occasionally showcase product demos for support and operations.

Minimum 5+ years of production experience in frontend development, including 3+ years building React Native apps in production (Fintech/Crypto).
Solid hands-on crypto experience is required — you’ve worked on production products dealing with on-chain transactions, multiple networks, and real user funds.
A background in non-custodial wallets is a strong plus.
Expert in React, React Native, and TypeScript, with solid testing discipline (Jest, Detox) and modern tooling — and you stay close to the React, React Native, and Expo ecosystem, bringing ideas that keep our codebase current.
Confident working with Git workflows, GitHub Actions , and automated pipelines for production releases.
Security-conscious — you understand that in a non-custodial wallet, every code path touches real user funds, and you build accordingly.
Skilled in technical research: evaluating trade-offs, testing hypotheses, and making data-driven architectural decisions.
Genuinely enjoy automating your own work with AI — not AI for its own sake, but as a way to ship faster and at higher quality. We’re an AI-forward team and want someone excited to push that frontier with us.
