• Contribute to the technical evolution of our Markets web platform, partnering with product and design to deliver engaging, performant, and accessible features.
• Implement and support features end-to-end: implementation → instrumentation → deployment → monitoring → iteration based on metrics.
• Implement and maintain experimentation capabilities (feature flags, A/B tests) to validate ideas quickly and safely.
• Integrate with backend APIs and collaborate with platform teams to build reliable, observable systems.
• Make contributions to the Go backend.
• Participate in code reviews, focusing on code quality, readability, and maintainability.
• Leverage AI tools to accelerate development velocity while maintaining high standards for security, correctness, and performance.
• Follow and help improve team standards for AI usage (prompt patterns, code review checklists, validation strategies).
• Contribute effectively to a fast-paced 0→1 environment, seeking opportunities to unblock others and take initiative.

Qualifications

• 3+ years experience building user-facing web applications using modern JavaScript/TypeScript and React.
• Proficiency in React, component-driven development, and state management patterns, with familiarity with libraries like NextJS, TanStack Query, Tailwind, Zustand.

• Solid understanding of JavaScript/TypeScript language features, idioms, and best practices.
• Understanding of performance optimization, responsive design, accessibility, and web standards.
• Experience integrating with backend APIs and collaborating with cross-functional platform/infra teams.
• Familiarity with CI/CD pipelines, testing strategies, and safe deployment practices for web applications.
• Team-first mentality, with a willingness to do what it takes to get the job done and a desire to strive for better.
• Experience using AI tools (Claude Code, Codex, Cursor, Copilot, etc.) to ship production code.
• Able to discuss how AI tools improve development workflow (e.g., boilerplate generation, debugging).
• Communicates technical concepts clearly to diverse audiences, including engineers and stakeholders.
• Thrives in a fast-paced environment where priorities evolve regularly and decisions are made quickly.
• Ability to collaborate cross-functionally across diverse teams.

Preferred Qualifications

• Previous experience in a startup environment.
• Contributions to open-source projects or technical communities.
