Frontend Engineer & UI Designer (Developer Tooling)

📍 Job Overview

Job Title: Frontend Engineer & UI Designer (Developer Tooling)

Company: SearchApi

Location: Lithuania (Remote)

Job Type: Full-Time

Category: Frontend Engineering & UI Design (Developer Tools)

Date Posted: 2026-06-22

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

Remote Status: Fully Remote

🚀 Role Summary

• Hybrid Builder-Designer: This role seeks an individual who excels at both designing user interfaces and implementing them directly into production code, focusing on developer-facing products.

• Product Ownership: Take full ownership of the frontend user experience, including the dashboard, API playground, documentation, and marketing site, ensuring a premium feel for developers.

• Hotwire-First Development: Leverage a server-rendered, component-based architecture (Ruby on Rails with Hotwire: Turbo & Stimulus) to deliver SPA-like polish without heavy client-side frameworks.

• Craftsmanship & Detail Focus: Thrive on meticulous attention to detail, optimizing performance (e.g., reducing jank) and ensuring high-quality, intuitive user experiences for a demanding developer audience.

📝 Enhancement Note: This role is unique in its demand for a singular individual to own both the design and implementation of critical developer-facing interfaces. The emphasis on "Hotwire-first" and native HTML signifies a preference for performance and a specific architectural philosophy, which applicants must understand and embrace. The "developer tools are unforgiving" statement highlights the high bar for quality and user experience expected.

📈 Primary Responsibilities

• Design and implement user interfaces for the customer dashboard, including usage analytics, request history, and billing sections, ensuring a calm and uncluttered experience.

• Develop interactive API playgrounds that provide immediate, visual feedback for developers testing requests, aiming for shareable and impressive user experiences.

• Own and maintain the documentation and marketing site, ensuring component system coherence, speed, and aesthetic appeal as the product evolves.

• Build honest and trustworthy data visualizations, translating raw metrics into clear, semantic charts for developer consumption.

• Champion a "native HTML first" approach, pushing the limits of Turbo Frames and Stimulus controllers to achieve SPA-like interactivity before resorting to additional dependencies.

• Actively manage and optimize the frontend codebase by cleaning up JavaScript bundles, removing dead CSS, and refactoring one-off controllers to maintain performance and maintainability.

• Translate Figma mockups into production-ready code, including ViewComponents, Stimulus controllers, and Tailwind CSS, ensuring seamless integration with the Ruby on Rails backend.

• Collaborate with the CEO and other team members, articulating design decisions and tradeoffs in writing (e.g., PR descriptions) and adapting designs based on usage data.

📝 Enhancement Note: The responsibilities heavily emphasize end-to-end ownership from design to production. The specific mention of "ViewComponents, Stimulus controllers, Tailwind, the whole thing" indicates a need for deep familiarity with the specified tech stack. The expectation to "hold the line on craft" and prioritize Hotwire implies a deep understanding of its benefits and limitations.

🎓 Skills & Qualifications

Education: No specific degree is mandated, but a strong portfolio demonstrating relevant skills and experience is paramount.

Experience:

• Minimum of 2-5 years of professional experience in frontend engineering and UI design.

• Proven track record of designing and building production-level frontend interfaces independently.

• Demonstrated experience in a server-rendered, component-based web application stack. Required Skills:

• Design Proficiency: Expertise in UI/UX design principles and practical experience with design tools like Figma.

• Frontend Development: Strong command of HTML, CSS (specifically Tailwind CSS), and JavaScript.

• Hotwire Ecosystem: Deep understanding and practical experience with Ruby on Rails, Hotwire (Turbo), and Stimulus controllers.

• Component-Based Architecture: Experience with component frameworks like ViewComponent for Ruby on Rails.

• Communication: Excellent written communication skills for articulating design decisions, tradeoffs, and technical explanations in PR descriptions and other documentation.

• Self-Direction: Ability to take vague requirements and develop a clear plan, execute independently, and manage one's own workload and priorities.

• Problem-Solving: Aptitude for tackling complex UI challenges, particularly within a Hotwire-centric framework, and finding elegant solutions.

• English Fluency: Proficient in both written and spoken English.

Preferred Skills:

• Experience designing or redesigning SaaS dashboards or developer consoles.

• Familiarity with data visualization libraries and best practices for presenting dense data.

• Experience with frontend performance optimization, including JavaScript bundle analysis and CSS cleanup.

• Contribution to design systems or open-source UI projects.

• Experience with frontend error tracking tools.

📝 Enhancement Note: The primary requirement is a portfolio that showcases a blend of design aesthetics and implementation capability. The emphasis on "good enough to ship" versus "pixel-perfect" implies a pragmatic approach to development, prioritizing delivery while maintaining high standards. The specific mention of "native HTML first" and "Turbo Frames over single-page-app frameworks" is a critical technical filter.

📊 Process & Systems Portfolio Requirements

Portfolio Essentials:

• Dual Showcase: Provide two distinct links to UIs you have personally designed and built. One should ideally be a landing or marketing page, and the other a product or application screen (e.g., a dashboard).

• Design Decision Rationale: For each portfolio piece, include a single-sentence explanation of the most challenging design decision you made and how you resolved it. This demonstrates critical thinking and problem-solving in design.

• Evidence of Polish: The designs must speak for themselves, demonstrating genuine taste and attention to detail beyond generic templates. Avoid submissions that lack specific, thoughtful design elements.

• Production Readiness: Submissions should reflect work that is live or has been deployed to production, indicating a level of execution beyond mockups.

Process Documentation:

• Design-to-Code Workflow: Articulate your process for translating Figma designs into functional frontend code, including how you manage component creation, styling, and interactivity.

• Problem-Solving Methodology: Be prepared to discuss how you approach and resolve complex UI challenges, particularly those inherent in maximizing Hotwire's capabilities for SPA-like experiences.

• Data Visualization Design: Demonstrate an understanding of how to design clear, honest, and trustworthy data visualizations that serve developer needs effectively.

• Code Quality & Maintenance: Explain your strategies for maintaining frontend code quality, including practices for cleaning up JavaScript bundles, managing CSS, and refactoring components.

📝 Enhancement Note: The portfolio is not just a collection of work but a critical assessment tool. The emphasis is on self-driven design and self-executed implementation, with a clear articulation of design rationale. The "Octopus Tentacle" instruction is a direct test of attention to detail and reading comprehension.
