Senior Frontend & UI Lead

📍 Job Overview

Job Title: Senior Frontend & UI Lead

Company: Avaron AB

Location: Stockholm, Sweden

Job Type: Full-time

Category: Frontend Engineering / UI/UX Leadership

Date Posted: February 23, 2026

Experience Level: Senior (10+ years)

Remote Status: On-site

🚀 Role Summary

• Lead the end-to-end ownership of the frontend architecture and overall user experience for a next-generation workshop ordering platform.

• Drive user-centric design by deeply understanding workshop workflows and translating them into intuitive, efficient user interfaces.

• Make critical design and implementation decisions within a unified workflow, directly turning user needs into production-ready UI.

• Foster strong collaboration with product, backend engineering, and business stakeholders in a high-autonomy, cross-disciplinary team environment.

• Leverage AI-assisted development workflows to enhance iteration speed and delivery output.

📝 Enhancement Note: This role is not a typical "frontend developer" position. The emphasis on "ownership of UX outcomes," "making design and implementation decisions in one unified workflow," and "operating across product, design, and engineering disciplines" indicates a lead role that blends technical frontend expertise with strategic UX leadership and product sensibility. The candidate is expected to be a driver of the user experience strategy, not just an executor of designs.

📈 Primary Responsibilities

• Architect and maintain the frontend codebase and infrastructure, ensuring scalability, performance, and maintainability.

• Define and implement user journeys that streamline complex workshop ordering processes, enhancing operational efficiency.

• Directly translate user research and business requirements into functional, high-quality UI components and features.

• Actively participate in cross-functional team meetings, contributing to product strategy, prioritization, and technical roadmap discussions.

• Champion and integrate AI-assisted development tools and techniques to optimize the development lifecycle and improve delivery velocity.

• Establish and monitor key UX quality metrics, such as task completion rates, time-on-task, and error rates, to drive continuous UX improvement.

• Facilitate decision-making processes at the intersection of product vision, user experience design, and technical feasibility.

• Present technical and design decisions clearly to both technical and non-technical stakeholders through presentations and written communication.

📝 Enhancement Note: The responsibilities highlight a blend of strategic technical leadership and hands-on development. The expectation to "own the frontend architecture and the overall user experience" and "apply AI-assisted development workflows" points to a forward-thinking role focused on innovation and efficiency within a lean, agile team structure.

🎓 Skills & Qualifications

Education: While no specific degree is mandated, a Bachelor's or Master's degree in Computer Science, Software Engineering, Human-Computer Interaction, or a related field is often beneficial for this level of strategic responsibility. Equivalent practical experience will also be highly valued.

Experience: Minimum of 10+ years of progressive experience in frontend engineering, with a significant portion dedicated to leading UI/UX initiatives and taking ownership of user experience outcomes.

Required Skills:

• Proven track record as a Senior or Lead Frontend Engineer with demonstrable ownership of UX outcomes.

• Expertise in taking a user problem from discovery through to a deployed solution independently, minimizing reliance on traditional design handoff processes.

• Strong ability to operate effectively across product management, UX design, and backend engineering functions.

• Hands-on, practical experience integrating and utilizing AI-assisted development tools in daily workflows, with a clear understanding of their value proposition.

• Extensive experience working within small, high-autonomy teams that prioritize collaborative decision-making and self-direction.

• Deep proficiency in modern frontend technologies: React, Next.js, and TypeScript.

Preferred Skills:

• Experience with CSS frameworks and utilities such as Tailwind CSS.

• Familiarity with component libraries like shadcn/ui.

• Previous experience in the automotive or vehicle industry, particularly within the independent aftermarket.

• Background in Human-Machine Interface (HMI) design or interface design specifically for operational/workshop environments.

📝 Enhancement Note: The emphasis on "ownership of UX outcomes" and "making design and implementation decisions in one unified workflow" suggests that candidates without a formal design background but with strong UX intuition and practical application will be competitive. The requirement for AI-assisted development experience is a key differentiator.

📊 Process & Systems Portfolio Requirements

Portfolio Essentials:

• A portfolio that showcases end-to-end ownership of user experience initiatives, demonstrating how you've taken a user problem from initial concept to a deployed solution.

• Case studies highlighting your ability to understand complex workflows (e.g., workshop operations) and translate them into intuitive, efficient user interfaces.

• Examples of frontend architecture decisions and their impact on platform scalability, performance, and maintainability.

• Documentation or examples of how you have defined, tracked, and improved UX quality using behavioral metrics (e.g., task completion rate, time-on-task, error rates).

Process Documentation:
