Frontend Engineer
Tech Holding
Role Description
We are seeking a Front-End Engineer, for a project-based assignment, to join cross-functional product squads and take ownership of the UI layer end-to-end. This role requires strong expertise in modern frontend development, component architecture, state management, performance optimization, and user experience. You will work closely with Node.js backend engineers, designers, product managers, and client stakeholders to deliver high-quality digital products while helping shape frontend standards and best practices.
Core Stack
- React 18+
- TypeScript
- Next.js
- React Query / TanStack
- Zustand / Redux
- Tailwind CSS
- Node.js (API integration)
- Storybook
- Vitest / Playwright
- Azure Static Web Apps
- LLM UI Patterns
- REST / GraphQL
- Microsoft Azure
- AI-assisted development
Key Responsibilities
- Architect and build production React applications: component design, state management, routing, and data fetching with TypeScript throughout.
- Translate product requirements and Figma designs into polished, accessible, performant UIs that delight users.
- Own the front-end layer of full-stack features: collaborate with Node.js backend engineers, consume APIs cleanly, and surface data with clarity.
- Build and maintain shared component libraries with Storybook: writing components others will actually want to reuse.
- Instrument and optimize performance: Core Web Vitals, bundle analysis, lazy loading, memoization, and render profiling.
- Write meaningful test coverage with Vitest, React Testing Library, and Playwright: tests that catch real problems, not just cover lines.
- Integrate AI-powered UI patterns: streaming responses, generative content displays, real-time feedback loops as these become features in client products.
- Use AI tools (Copilot, Claude, etc.) actively in your workflow to accelerate development, code review, and documentation.
- Participate in design reviews, architecture discussions, and code reviews: raising the bar across the front-end team.
Qualifications
- 3+ years of professional front-end engineering experience with React and TypeScript: you think in components and types by default.
- Deep knowledge of modern React: hooks, context, concurrent features, Suspense, and performance patterns.
- Strong TypeScript fluency: you write types that document intent and catch bugs at compile time, not runtime.
- Experience with Next.js or similar SSR/SSG frameworks, including routing, data fetching strategies, and deployment considerations.
- Solid grasp of CSS: layout models, responsive design, animation, and at least one utility-first approach (Tailwind preferred).
- Comfort consuming REST and GraphQL APIs and handling async state cleanly (React Query, SWR, or similar).
- Working knowledge of Node.js: enough to read backend code, debug integrations, and occasionally contribute small API changes.
- Demonstrated use of AI tools in your daily development workflow: you can speak concretely to how they've changed how you work.
- Experience writing and maintaining tests across unit, integration, and E2E layers.
- Excellent async written communication in English: you articulate front-end trade-offs clearly to non-engineers.
Nice to have
- Hands-on experience with Algolia (highly preferred).
- Experience with Next.js, React Server Components, or micro-frontend architectures.
- Experience with message queues (Kafka, RabbitMQ, SQS).
- Familiarity with serverless or edge runtimes.
- Experience with Docker and containerized environments.
- Exposure to Kubernetes or infrastructure-as-code tools (Terraform, Pulumi).
- Experience with domain-driven design or clean architecture principles.
- Experience mentoring engineers or contributing to open-source projects.
