Job Summary

We are building a modern cloud platform that integrates AWS serverless APIs, containerized firmware emulation running in EKS, and intelligent orchestration workflows. While the backend teams handle large-scale cloud services and device simulation, we need a dedicated frontend developer to turn this complex system into a clean, intuitive, and powerful user experience.

• Implement clean and maintainable front-end logic, state management, and component patterns

• Collaborate with designers and product teams to deliver UI that is clear, intuitive, and visually consistent
• Work closely with backend engineers to define API usage and ensure smooth front-end integration
• Participate in code reviews, contribute to UI documentation, and help improve team front-end practices
• Write basic unit and integration tests for React components
• Assist in improving usability, performance, and overall UI/UX quality

Required Skills / Qualifications

• 0-2 years of professional UI/Frontend development experience
• Solid understanding of HTML5, CSS3, and responsive design principles
• Experience with component composition and reusable UI patterns
• Familiarity with state management tools (Context, hooks, or libraries like Zustand/Redux)
• Basic understanding of calling REST APIs from React applications
• Comfort working with Git and collaborative development workflows
• Strong attention to detail and interest in UI quality and user experience
• Willingness to learn from senior developers and grow your technical depth

Assets

• Experience with TypeScript (even partial exposure is a plus)
• Familiarity with UI testing (Jest, Testing Library, Cypress, Playwright)
• Exposure to design systems or component libraries
• Experience with build tools (Vite, Webpack) and modern CI workflows
• Understanding of cloud concepts or backend technologies (AWS, APIs, containers)

No prior AI or AWS experience? Candidates eager to learn will be supported and gain hands-on exposure in production.
