Description

Why us? At CDQ, we offer a flexible work environment and the opportunity to contribute to the development of Cloud Apps, a web platform that helps users interact with CDQ APIs and products through a modern interface. Our engineering setup includes a React application built with TypeScript and Vite, a shared NestJS backend, and automated testing across multiple levels. You will be part of a small, collaborative team of three frontend engineers, which means a high degree of flexibility, ownership, and direct influence on the entire web application - from architecture and technical decisions to code quality, user experience and the evolution of our web app. Brief job description We are seeking a highly experienced Senior Software Developer with strong React expertise to join our team at CDQ. The ideal candidate must have at least 5+ years of professional experience in frontend or fullstack development. This role is strongly frontend-focused, with approximately 80–90% of the work centered on React, and 10–20% involving collaboration on and occasional implementation work in our NestJS backend. What is key about this position? Your mission: Your daily tasks on the job - Develop and evolve a modern React web application, with a strong focus on clean architecture, scalability, and maintainability. - Implement and deliver product features end-to-end, including frontend views, business logic, and integrations with backend APIs. - Refactor and improve existing codebases, migrating legacy logic into well-structured, reusable frontend solutions. - Collaborate within a small, high-impact team on technical decisions, solution design, and continuous product improvement. - Contribute to shared UI components, design system adoption, and engineering standards, ensuring a consistent, intuitive experience across the application. - Support backend development in NestJS when needed, enabling smooth frontend-backend collaboration. - Take ownership of UI quality and user experience, proactively identifying and resolving usability issues and inconsistencies. Deine Mission Your mission Your qualifications: - Strong React & TypeScript expertise, including frontend architecture, component design, maintainability, and clean coding practices. - Experience building production-grade SPA applications, including state management, API integration, routing, authentication flows, error handling, and accessibility. - Familiarity with modern frontend tooling and workflows, such as Vite, ESLint, Prettier. - Hands-on experience with testing at multiple levels, using tools like Vitest, Jest, Testing Library, and Playwright. - Good knowledge of HTML, CSS/SCSS, and responsive, accessible UI development. - Practical experience with Node.js and NestJS, sufficient for collaboration and occasional backend implementation. - Experience leveraging AI-powered developer tools (e.g. GitHub Copilot or similar models) for code generation, refactoring, understanding context, and improving overall development productivity. - Nice to have: experience with Docker, MongoDB, Kafka, CI/CD pipelines (e.g. GitHub Actions). - Strong sense of UI ownership and responsibility for how the product looks, feels, and behaves from the user's perspective. - Understanding of common UX patterns in modern SaaS applications, including navigation, data-heavy views, form flows, empty/loading/error states. - Ability to think end-to-end across user journeys, not just individual components. - Fluent English communication skills How you thrill us: - experience with Docker, MongoDB, Kafka, CI/CD pipelines (e.g. GitHub Actions).
