Duties/scope:


  • Leading frontend initiatives, defining coding standards, driving architecture and design, creating guidelines and documentation.
  • Designing and creating high-performance and visually-rich applications (e.g., server dashboards, game management UIs, live ops tools and any other tools used by developers and non technical people) ensuring responsiveness and cross-device compatibility.
  • Optimizing and enhancing front-end build performance, while ensuring seamless integration and interoperability with backend systems and APIs.
  • Reviewing and approving complex frontend pull requests, ensuring code quality, consistency, performance, accessibility, and alignment with architectural guidelines.
  • Identifying and managing technical debt, making recommendations for refactoring or improvements in code quality and system architecture.
  • Share technical expertise with less experienced developers through hands-on support and collaborative problem-solving. Promote a culture of learning by explaining architectural decisions, frontend patterns, and best practices.
  • Integrating and maintaining various APIs and third-party tools.

  • Deep understanding of UI/UX principles, with experience leading UI/UX design decisions with little to no support.
  • Solid knowledge of REST APIs, including integration and data management in frontend applications.
  • Commercial experience with testing frameworks like ViteTest, React Testing Library, and Cypress.
  • Familiarity with linting and code formatting tools (e.g., ESLint, Prettier).
  • Prior mentoring experience helping less experienced developers grow their skills.
  • Proficiency in Polish and English (spoken and written) is essential for cross-functional collaboration.
  • Familiarity in utilizing AI tools in everyday work.



Nice to have:


  • Familiarity with popular UI component libraries like Material-UI or Shadcn.
  • Experience integrating frontend applications with Python or C# based services.
  • Familiarity with AWS or GCP cloud platforms is a plus, especially for deploying, managing, or integrating cloud-based services (e.g., cloud storage) into frontend applications.
  • Experience with Sentry for monitoring and tracking frontend application errors.
  • Familiarity with Docker to containerize frontend applications as well as debugging them.
  • Experience with ArgoCD and Kubernetes for automated builds, tests, and deployments.
  • Experience with WebSockets to build real-time, interactive web applications, such as live dashboards, chat systems, or notifications.
  • Knowledge of using HTML5 Canvas or frameworks like Fortune Sheet for creating custom, data-heavy visual interfaces or game telemetry dashboards.
  • Experience working alongside Unity or integrating front-end tools with game engines/mobile phones.
