Job brief

DarkLion Studio is looking for a Senior Front-End Engineer to lead the development of cutting-edge digital experiences. This role requires a strong command of modern front-end technologies, a keen eye for UI/UX, and the ability to collaborate seamlessly with designers and back-end engineers. If you thrive in a fast-paced, creative environment and are passionate about crafting pixel-perfect, high-performance interfaces, we’d love to have you on board.

Skills & Responsibilities

  • Develop and optimise user-facing features using modern JavaScript frameworks (Next.js, React, Vue, or Angular)
  • Ensure seamless performance across devices and browsers with a mobile-first approach.
  • Write clean, maintainable, and scalable code following industry best practices.
  • Collaborate closely with UI/UX designers to translate design systems into highly functional and visually engaging applications.
  • Integrate APIs and manage application state using Redux, Zustand, Jotai, Context API, or similar tools.
  • Work in tandem with backend and AI teams to consume and visualize AI-generated data such as text, diagrams, vector outputs, and analytics.
  • Build dynamic UIs that interact with AI features like chat interfaces, smart suggestions, recommendation engines, and custom visual outputs.
  • Handle and display complex AI responses in a user-friendly, secure, and performant manner — including streamed outputs, markdown, code blocks, charts, or embeddings.
  • Implement robust error handling, loading states, and fallback UIs for unpredictable AI behavior.
  • Lead technical discussions, mentor junior developers, and participate in code reviews.
  • Optimize web applications for performance, speed, and scalability.
  • Stay current with trends in frontend and AI-powered UX design to drive innovation.

We want you onboard, if you have

  • 4+ years of experience in frontend development with a strong portfolio of responsive, performant web applications
  • Advanced proficiency in Next.js and React.js, including SSR, SSG, and ISR.
  • Solid knowledge of TypeScript and scalable component architecture.
  • Hands-on experience in state management (Redux Toolkit, Zustand, Jotai, or Context API).
  • Strong UI skills using Tailwind CSS, Chakra UI, Material UI, or Styled Components
  • Experience integrating and handling RESTful APIs and GraphQL using Axios, Apollo Client, or URQL.
  • Familiarity with authentication methods including NextAuth, Firebase Auth, OAuth, or JWT.
  • Proven ability to build interfaces that consume and visualize AI-generated content (e.g., from OpenAI, LangChain, or custom AI APIs).
  • Experience with real-time data rendering, streaming outputs, and building interactive visualizations (charts, diagrams, or vector spaces).
  • Understanding of performance techniques: lazy loading, code splitting, and image optimization.
  • Knowledge of SEO best practices and Next.js built-in SEO capabilities.
  • Unit testing and frontend testing using Jest, React Testing Library, Cypress, or Playwright.
  • Familiarity with CI/CD workflows and deployment using Vercel (preferred), Netlify, or other cloud platforms.
  • Experience with internationalization (i18n) using next-i18next or equivalent tools.
  • Bonus: Experience working with AI-driven UX, chat interfaces, or visual editors based on AI logic.
