Senior Frontend Engineer (React + Redux)

We’re a U.S.-based SaaS startup seeking an expert React/Redux Frontend Engineer to work directly with our hands-on CTO. This long-term role suits someone who values clean architecture, scalable code, and thoughtful UI design.

What You’ll Do

• Lead development and scaling of a React.js + Redux application with modern patterns (hooks, context, lazy loading).
• Architect maintainable, modular component structures and establish state management standards with Redux Toolkit.
• Refactor and optimize for performance — memoization, code splitting, dynamic imports, and rendering efficiency.
• Ensure clean, predictable data flow and consistent UI behavior across the app.
• Collaborate with backend and design teams to ship reliable, high-quality features.
• Review code, uphold best practices, and mentor other frontend contributors.

• Expert in React.js and Redux, including hooks, middleware, and architectural patterns.
• Deep understanding of JavaScript (ES6+), async flow, and browser performance.
• Proven experience structuring and scaling production-grade frontends.
• Strong debugging and profiling skills (React DevTools, performance audits).
• Familiarity with build and automation tools (Webpack, Babel, npm scripts).
• Committed to clean, testable, and maintainable code.
• Excellent communication and collaboration; available during U.S. hours.

• Direct collaboration with a technical founder/CTO.
• Long-term role solving real product challenges — not just CRUD work.
• 100% remote, fast-paced, small-team environment.
• Clear path to Lead Frontend or UI Architect as the product scales.
