About the Role

As a Frontend Engineer, you will take ownership of the design, development, and continuous improvement of complex frontend applications. You will work closely with backend, AI, and product teams to build intuitive interfaces that connect users with powerful backend services, data platforms, and AI-powered capabilities.

You will contribute not only through coding, but also through frontend architecture, state management, performance optimization, testing, and the creation of reusable components that can scale across products.

What You’ll Do

• Design, build, and maintain complex frontend applications primarily using React and TypeScript; experience with Angular is also valuable.
• Define scalable frontend architecture, including component structure, data flow, and maintainable application patterns.
• Make thoughtful decisions around state management using tools such as Redux, Zustand, NgRx, and React Hooks.
• Build highly interactive, communication-heavy, and real-time product experiences using technologies such as WebSockets or Socket.io.
• Collaborate closely with backend and AI teams to integrate APIs and create AI-powered features, including chat interfaces, intelligent assistants, and GenAI workflows.
• Develop reusable UI components and contribute to scalable design systems using tools such as Storybook, Material UI, Tailwind CSS, or Angular Material.
• Build dashboards and translate backend data into clear, actionable visualizations using libraries such as Chart.js or D3.js.
• Ensure frontend applications are performant, reliable, and production-ready.
• Implement and maintain unit, integration, and end-to-end testing using tools such as Jest, Cypress, or Jasmine.
• Collaborate on deployment workflows and work effectively within cloud-based and containerized environments.

What We’re Looking For

• Strong professional experience building production frontend applications with React and TypeScript.
• Solid understanding of frontend architecture, component design, state management, and application scalability.
• Experience integrating frontend applications with REST APIs, backend services, and complex data flows.
• Experience building interactive or real-time features using WebSockets, Socket.io, or similar technologies.
• Familiarity with frontend testing practices, including unit, integration, and end-to-end testing.
• Experience creating reusable components, shared UI libraries, or design systems.
• Experience with data visualization libraries such as Chart.js, D3.js, or similar.
• Understanding of performance optimization, browser behavior, debugging, and production reliability.
• Exposure to Docker, cloud environments, CI/CD, and modern deployment workflows.
• Strong problem-solving skills, ownership mindset, and ability to work independently in a remote environment.
• Advanced English communication skills, both written and spoken.

What We Offer

• A full-time, long-term contractor opportunity.
• The flexibility of a fully remote work environment.
• The opportunity to work on advanced frontend systems supporting AI and GenAI products.
• Ownership of technically challenging projects with real enterprise impact.
• Collaboration with an international and highly skilled team.
• A fast-paced environment that encourages innovation, autonomy, and continuous professional growth.
