About Us

Bullet is building the next generation of trading infrastructure on Solana — lightning-fast, sleek, and designed for serious users. Founded by a team with backgrounds in high-frequency trading (HFT), top Silicon Valley tech companies and leading crypto exchanges. We’re backed by world-class investors including Electric Capital, Jump Capital, Race Capital, Wintermute, and more.

Our team previously launched Zeta Markets, one of the top perpetual DEXs on Solana with over $15B in volume traded in 2025. With Bullet, we’re pushing the boundaries even further: 3ms trade latency, thousands of TPS, and a full-featured perps and spot DEX built for pros and retail alike.

Role: React Front-End Developer

We're looking for a talented and product-obsessed React developer to help build a fast, beautiful, and intuitive trading UI — desktop-first, mobile-optimized, and responsive across all devices. This isn’t just about dashboards; it’s about creating a modern trading experience that feels as seamless as the best consumer fintech apps — but powered by decentralized rails.

What You’ll Do

• Build and maintain the core front-end of Bullet across web and mobile browsers using React + TypeScript.
• Collaborate with design, product, and backend teams to ship high-quality features and UX flows.
• Craft responsive UIs that feel native on both desktop and mobile — with sharp performance, clean animations, and real-time data.
• Integrate REST and WebSocket APIs for trading, market data, authentication, and notifications.
• Own performance, accessibility, and usability standards across the app.
• Help shape onboarding, portfolio tracking, order placement, and more — turning complex DeFi actions into intuitive user flows.
• Maintain robust testing and deployment pipelines with a high bar for code quality and reliability.

You Might Be a Fit If You Have:

• 3+ years of experience building production-grade React apps.
• Strong TypeScript and React hooks proficiency.
• Experience with Next.js and React 19.
• Experience building responsive web UIs that work across desktop and mobile.
• Solid grasp of front-end performance optimization, animation, and state management.
• Comfortable integrating with both REST and WebSocket APIs.
• Experience or interest in financial interfaces, trading dashboards, or data-heavy applications.
• Appreciation for good design and a sharp eye for detail.
• Familiarity with analytics, error tracking, and deployment tools (Amplitude, Sentry, Vercel etc.).

Bonus Points:

• Previous experience in fintech, crypto, or trading UIs.
• Experience with charting libraries (e.g. TradingView).
• Exposure to onboarding funnels and user education in web apps.
• Familiarity with WASM, service workers and SSR frameworks (Next.js).
• Interest in Solana and DeFi ecosystems.

Why Join Bullet?

• Help shape the future of decentralized trading on Solana.
• Work with a world-class team that values product, performance, and pixel-perfect execution.
• Operate in a fast-paced, high-trust environment where you’re given ownership and autonomy.
