Job Description
We are looking for a Mid-Level React Native Engineer to help us evolve our mobile architecture into a modular, multiplatform system. This role is focused on enabling rapid development of new consumer apps by composing reusable building blocks from our existing stack and delivering them through high-quality React Native applications.
This is a hands-on engineering role where you will contribute to a new way of building apps at Blockchain.com—making it possible to quickly launch new crypto experiences across iOS and Android.
WHAT YOU WILL DO
- Build and maintain React Native applications that leverage shared modules from our existing mobile and backend systems
- Contribute to a modular architecture that enables rapid assembly of new apps from reusable components (auth, wallet, trading, on-ramp/off-ramp, etc.)
- Collaborate with mobile, backend, and product teams to define clean interfaces between modules and ensure seamless integration
- Translate product ideas into shippable mobile experiences with a focus on speed, quality, and scalability
- Use AI-assisted development tools (e.g., Claude, Codex) to accelerate implementation, while ensuring correctness, performance, and maintainability
- Validate and review AI-generated code, maintaining a high bar for quality and security
- Contribute to shared UI patterns, component libraries, and developer tooling for faster app development
- Participate in the full development lifecycle: prototyping, building, testing, releasing, and iterating
- Support app store deployments, releases, and post-launch improvements
- Debug issues across the stack and improve reliability and performance of mobile apps
WHAT YOU WILL NEED
- 2–5 years of experience in software engineering, with hands-on experience in React Native
- Strong proficiency in JavaScript/TypeScript and modern mobile development practices
- Experience building and shipping production mobile apps (iOS and/or Android)
- Solid understanding of component-based architecture and modular design principles
- Ability to work with APIs and integrate complex backend-driven features
- Experience using AI developer tools (e.g., Claude, Codex) or strong interest in leveraging them effectively
- Strong attention to detail and ability to review and validate code for quality and correctness
- Familiarity with mobile performance, debugging, and testing best practices
- Good communication skills and ability to collaborate across teams
NICE TO HAVE
- Experience with native mobile development (Swift, Kotlin, or Java)
- Experience working on shared codebases or cross-platform architectures
- Familiarity with crypto, wallets, or financial applications
- Experience integrating third-party services (e.g., payments, authentication, on-chain providers)
- Experience with CI/CD pipelines and app store release processes
- Exposure to secure key management, authentication flows, or MPC wallets
COMPENSATION & PERKS
- Competitive full-time salary based on experience and meaningful equity in an industry-leading company
- This is a role based in our Palermo office, with a mandatory in-office presence four days per week.
- The opportunity to be a key player and build your career at a rapidly expanding, global technology company in an exciting, emerging industry.
- Performance-based bonuses
- Apple equipment provided by the company
- Work from Anywhere Policy: You can work remotely from anywhere in the world for up to 20 days per year.
