## About Us Bullet is building a cutting-edge decentralized perpetuals trading platform on Solana. Founded by a team from HFT, Silicon Valley tech, and crypto exchanges. Backed by Electric Capital, Jump Capital, Race Capital, Wintermute, and others. We previously built Zeta Markets, one of the top perpetual DEXs on Solana with over $15B in volume traded in 2025. Bullet is the next step: 500µs trade execution latency, 10k+ transactions per second, full-featured perps and spot DEX for pros and retail. ## The Role We need a senior frontend engineer who can own large features end-to-end. You'll work with design and product to define solutions to ambiguous problems, then ship them. Small, results-driven frontend team. We care about product quality and execution speed. **What You'll Do** - Own features from technical design through production - Build and maintain Bullet's trading UI in React, TypeScript, and Next.js (App Router, Server Components, Server Actions) - Ship fast, polished interfaces for trading, portfolio management, and onboarding. Desktop-first, with mobile web and some React Native work. - Make tradeoffs between speed and quality. Know when to ship and when to polish. - Work across the stack when needed. We're frontend-focused but you should be comfortable touching APIs and some infrastructure. - Participate in code reviews. We take this seriously and expect thoughtful review of others' code, not just rubber stamping. - Communicate clearly verbally and in writing. Good async communication helps depending on timezone overlap. ## Requirements - 5+ years building production React applications - Deep experience with Next.js (App Router preferred), including SSR, SSG, ISR, Server Actions, and API routes - Ability to create clean abstractions: reusable components, custom hooks, shared utilities that work across desktop and mobile - Solid grasp of frontend performance optimization, animation, and state management - Comfortable working across the full stack when needed - Experience with financial interfaces, trading dashboards, or data-heavy applications (or genuine interest) - Sharp eye for design and detail - Familiarity with analytics, error tracking, and deployment tools (Amplitude, Sentry, Vercel) **Bonus** - Fintech, crypto, or trading UI experience - Charting libraries (TradingView) - Databases (PostgreSQL, Redis) and ORMs (Prisma, Drizzle) - WASM, service workers, edge functions - Caching strategies (Redis, CDN, in-memory) - Interest in Solana and DeFi ## Beyond Technical Skills We're a small team so a lot comes down to how you work, not just what you know. We want someone who takes ownership of their work and doesn't need to be chased. If you say you'll ship something, you ship it. You're pragmatic about tradeoffs and don't over-engineer. You communicate proactively when things are blocked or slipping. You care about whether what you're building actually moves the needle, not just whether the code is clean. If you need a lot of structure and process to be effective, this probably isn't the right fit. ## Why Bullet - Real ownership and autonomy - Strong team, low bureaucracy - Hard technical problems in a zero-to-one product - Competitive compensation + meaningful equity When applying, mention the word **CANDYSHOP** to show you read the job post completely.
