This role sits at the intersection of fintech innovation and blockchain technology, focused on building and scaling a non-custodial crypto wallet and card ecosystem used by a global user base. You will work on high-impact user-facing features such as transactions, balances, swaps, bridges, on-ramp flows, and card/payment experiences. The environment is highly product-driven, where engineering, design, and product teams collaborate closely to shape the future of digital finance. You will take full ownership of critical mobile application components, ensuring performance, security, and usability at scale. The role offers significant autonomy, end-to-end responsibility, and the opportunity to influence architecture and product direction. It is ideal for engineers passionate about crypto, mobile performance, and modern React Native ecosystems.
Accountabilities:
- Own and evolve core wallet functionality including send/receive flows, balances, transaction history, swaps, bridging, and on/off-ramp experiences.
- Lead development of extended product features such as crypto card integration, IBAN-like payment systems, subscriptions, onboarding, and multi-provider expansion across regions.
- Drive full lifecycle ownership of features from architecture and planning to implementation, testing, deployment, monitoring, and iterative improvements.
- Collaborate closely with Product and Design teams to translate user needs into scalable, high-quality mobile experiences.
- Partner with QA and backend teams to ensure reliability through testing strategies, documentation, and reproducible workflows.
- Participate in on-call rotation and contribute to system reliability and incident resolution.
- Produce clear technical documentation and occasionally support internal demos for stakeholders and support teams.
Requirements:
- 5+ years of frontend engineering experience, including at least 3+ years in React Native production applications.
- Strong background in fintech or crypto products, ideally with experience in non-custodial wallets and on-chain transactions.
- Expert-level proficiency in React, React Native, and TypeScript with solid testing practices (Jest, Detox).
- Experience with modern mobile tooling and libraries such as React Query, Redux Toolkit, Zustand, WalletConnect, Reanimated, Skia, Sentry, and Firebase.
- Strong understanding of blockchain ecosystems including EVM-compatible networks, Bitcoin, Tron, Solana, and TON.
- Comfortable working with Git workflows, CI/CD pipelines, and automated production release systems.
- Strong security mindset, particularly around applications handling real user funds.
- Ability to conduct technical research, evaluate trade-offs, and make data-driven architectural decisions.
- Comfortable using AI tools to improve development speed and quality in a practical, engineering-focused way.
- Upper-Intermediate English level; fluency in Russian is required.
Benefits:
- Fully remote work within an international and agile engineering environment.
- High-impact role with ownership over key product areas in a fast-growing fintech ecosystem.
- Strong engineering culture supporting modern tools, experimentation, and technical autonomy.
- Competitive salary based on experience and performance.
- Clear career growth opportunities in a forward-thinking product organization.
- Transparent feedback culture focused on ownership, collaboration, and measurable impact.
