About Us:

Bullet was started by a tightly-knit team with backgrounds in high frequency trading (HFT), top Silicon valley tech companies and prominent crypto exchanges. They are backed by some of the leading investors in the crypto space such as Electric Capital, Jump Capital, Race Capital, Wintermute and many more. The team previously built Zeta Markets, a leading perps DEX which facilitated over $15B in trading volume in 2025. They are looking to redefine the trading experience on Solana with Bullet, which boasts 3ms trade execution latency, thousands of TPS and a full featured perps and spot DEX.

Role Overview:

We are seeking a talented React Native Developer to help us deliver a sleek, responsive and functional trading front-end for mobile (and web). If you've traded on or previously built consumer-facing financial applications you'll understand the need for similarly ergonomic mobile-native UI/UX to make its way to DeFi applications like Bullet.

Key Responsibilities:

• Work with the front-end team to deliver the mobile app using React Native (iOS and Android) as well as the core React web app.
• Collaborate closely with product, design, and backend teams to build a seamless trading experience.
• Implement clean, scalable UI/UX optimized for retail users and high-conversion onboarding flows.
• Ensure performance, responsiveness, and reliability under high user load.
• Integrate with APIs for trading, analytics, authentication, and notifications.
• Implement features like real-time price updates, price charting, portfolio tracking, and simplified order placement.
• Debug issues, write tests, and maintain a strong deployment pipeline.

Required Qualifications:

• 3+ years of production React Native experience.
• Experience with Expo.
• Strong proficiency in TypeScript and React hooks.
• Experience with push notifications, deep linking and app store deployment.
• Experience integrating REST and WebSocket APIs.
• UI animation experience (Reanimated, Lottie, etc.).
• A strong appreciation for design and UX.
• Robust understanding of mobile app architecture and security best practices.

Preferred Qualifications:

• Experience building consumer fintech, trading or DeFi apps.
• Exposure to onboarding flows and user education in apps.
• Familiarity with analytics tools like Sentry and Amplitude.

What We’re Looking For:

• Relentless executors who prioritize shipping high-quality code.
• High ownership mentality, capable of solving complex problems with minimal oversight.
• Exceptional communication and collaboration skills, able to articulate ideas clearly and work effectively with others.

Why Join Us?

• Shape the future of decentralized finance on Solana with a team that values innovation and execution.
• Operate in a high-autonomy environment where your impact is immediate and visible.
• Tackle challenging technical problems alongside some of the brightest minds in the space.
• Competitive compensation package
