UI Developer

📍 Job Overview

Job Title: UI Developer

Company: Bloomreach

Location: Czechia (Remote OK)

Job Type: Full-Time

Category: Frontend Engineering / Design Systems

Date Posted: April 30, 2026

Experience Level: Mid-Level (2-5 Years)

Remote Status: Fully Remote (with office hubs in Bratislava, Brno, Prague)

🚀 Role Summary

• Implement and evolve a robust UI design system and component library, ensuring consistency and reusability across Bloomreach's Engagement application.

• Collaborate closely with product designers and frontend engineers to translate complex ideas into intuitive, performant, and visually appealing user interfaces.

• Develop and maintain a scalable SCSS framework, focusing on modern CSS architecture, modularity, and long-term maintainability.

• Leverage AI-powered tools to enhance development workflows, from code generation and refactoring to documentation and testing.

• Contribute to a culture of continuous improvement, actively participating in code reviews and proposing architectural enhancements for UI/UX.

📝 Enhancement Note: The role is positioned as a UI Developer with a strong emphasis on design systems and frontend architecture. While the title is "UI Developer," the responsibilities and required skills align with a specialized Frontend Engineer role focused on UI development and design system ownership. The "2-5 years" experience level, combined with the expectation to "co-own at least one part of the design system" within 90 days and "tackle most tasks on your own" within 180 days, indicates a mid-level position that requires practical experience and the ability to take ownership.

📈 Primary Responsibilities

• Design System Expansion & Maintenance:

  • Develop and implement reusable UI primitives (tokens, layout, form controls) and higher-level components compatible with Angular applications.
  • Ensure robust cross-browser compatibility and adherence to accessibility best practices (WCAG).
  • Act as a technical partner to designers, shaping the visual representation and behavior of components.
  • Maintain and enhance the internal "Showcase" or component gallery, serving as the single source of truth for design system documentation and usage examples.

• SCSS Framework Improvement:

  • Extend and update core SCSS functions, mixins, and utilities to promote efficient and maintainable styling practices.
  • Evolve the CSS architecture (layers, naming conventions, design tokens, theming) to ensure scalability as the product grows.
  • Proactively identify and eliminate legacy styles, dead code, and inconsistencies to improve performance and maintainability.

• New Design & Product Experience Implementation:

  • Update existing screens to align with the latest design specifications and interaction patterns.

  • Conduct research on best strategies for significant UI changes, considering component reusability and context.

  • Collaborate with product managers and designers to balance UX quality, technical feasibility, and delivery timelines.

  • Partner with QA and utilize AI-assisted testing tools to prevent regressions and ensure the quality of visual and structural changes.

📝 Enhancement Note: The responsibilities are broken down into three core areas: Design System, SCSS Framework, and Implementation. This structure clearly delineates the primary focus areas for the UI Developer, emphasizing their role in both building foundational UI elements and implementing user-facing features. The emphasis on "AI-powered tooling" and "AI-assisted testing" highlights a forward-thinking approach to development.
