- Deep understanding of mobile performance optimization, profiling, and debugging tools
- Experience with mobile CI/CD pipelines and app distribution through the App Store and Google Play
- Excellent communication and collaboration skills in a remote, async-friendly environment
- Comfortable operating autonomously in a fast-paced, product-led environment
- Passion for DeFi, open finance, and building tools that empower users

- Experience working with crypto wallets (e.g., MetaMask, WalletConnect, Rabby) and web3 connectivity on mobile
- Strong understanding of mobile security best practices, especially in a crypto context
- Experience with product analytics, user telemetry, and experimentation on mobile (e.g., A/B testing, feature flags)

What the job involves
- We’re building a greenfield mobile app from scratch — and we’re looking for a Mobile React Native Engineering Lead to own it
- As our first mobile engineer, you’ll play a foundational role in defining and building the future of Matcha on mobile
- This is a hands-on role where you’ll work closely with product, design, and engineering leadership to shape the app’s architecture, own key technical decisions, and eventually build and lead a mobile engineering team
- Lead the end-to-end development of our new React Native mobile app for iOS and Android
- Design and implement app architecture, state management, and mobile-specific infrastructure (e.g., release pipelines, telemetry, CI/CD)
- Collaborate closely with product, design, and backend teams to build seamless, intuitive, and performant DeFi experiences
- Own the mobile user experience and bring complex features (e.g., trading, signing, wallet connectivity) to life
- Maintain a high bar for code quality, testing, and performance through code reviews and technical mentorship
- Stay current with React Native and web3 best practices, tools, and community trends to continuously improve the app
- Define long-term technical direction for mobile and contribute to hiring and onboarding future mobile engineers
Our take
0x had its beginnings as a decentralized crypto exchange before its founders noticed a problem - while the apps built to facilitate crypto trading were functional, the user experience was usually terrible. 0x changed to become a decentralized exchange protocol instead, and provides a suite of APIs and tools so developers can build decentralized apps capable of competing with the likes of PayPal or Stripe for ease of use and functionality.
0x's product has wide appeal in the Web3 space and has grown a strong customer base including the likes of Coinbase, Robinhood and Polygon, and has a trading volume exceeding $125 billion. Having raised a large amount of capital in a 2022 funding round, it is focusing on expanding its team as well as its product range. While the crypto world is currently subject to intense volatility, 0x is enabling businesses to build apps and products that make the market more navigable. This will go a long way towards improving trust and stability in the sector.
