Position Overview

• The UX Lead HMI Design plays a key role in shaping and enhancing the user experience across the vehicle's infotainment system, including the Instrument Cluster (IPC), Head Unit, Head-Up Display (HUD), physical controls, and multimodal feedback such as sound and voice.
• This role involves contributing from the early stages of new design projects, while also proposing experience improvements for existing systems to ensure intuitive, safe, and emotionally engaging interactions while driving.
• The position requires strong system-level design thinking, the ability to analyze user behavior in real-world driving contexts, and the capability to anticipate and define future UX directions. The ideal candidate actively researches emerging automotive technologies (e.g., ADAS, electrification, personalization, multimodal interaction) to deliver forward-thinking UX concepts that are both innovative and feasible aligned with global design standards and product strategy.
  
  

Responsibilities

• Propose and develop design concepts for both new infotainment projects and improvements to existing systems, covering components such as the Instrument Cluster (IPC), Head Unit, HUD, physical controls, and sound/voice feedback.
• Analyze user behavior, pain points, and usage scenarios in the driving context to define user-centric interaction models
• Research emerging trends and technologies in the automotive industry (e.g., ADAS, EV interfaces, personalization, multimodal interaction) to shape future-ready UIUX strategies.
• Create wireframes, user flows, and low- to mid-fidelity prototypes to communicate design concepts effectively to internal stakeholders
• Collaborate closely with UI/UX designers, researchers, product owners, and software engineers to ensure UX ideas are translated into practical and implementable designs
• Participate in usability testing, expert reviews, and in-vehicle validation activities to assess and iterate on UX proposals
• Benchmark competitor systems (both within and outside the automotive domain) to identify best practices and opportunities for differentiation
• Produce clear and structured UX documentation (e.g., behavior specifications, user flows) to support development and validation teams
  
  

Requirements

• Education & Experience
• Bachelor's or Master's degree in UX Design, Interaction Design, Human Factors, Cognitive Psychology, Industrial Design, or related fields.
• At least 7 years of experience working in UX design, with a minimum of 3 years in a UX Lead role, focusing on defining UX direction, proposing design strategies, and ensuring experience quality across complex digital systems.
• Hands-on involvement in both new feature ideation and iteration of existing systems.

• Designing wireframes and interactive prototypes
• Skilled in user research methods and experience validation, including:
• Usability testing, A/B testing, eye-tracking, driver distraction testing, and simulated/real driving scenarios
• Applying UX heuristics and conducting expert reviews
• Ability to define and manage UX design patterns for standard interaction behaviors (e.g., notification, state change, confirmation).
• Able to define and track UX performance indicators (e.g., task completion rate, time on task, error rate, SUS score) and propose data-driven design improvements.
• Change Management & UX Roadmap Skills
• Able to manage UX change requests systematically, ensuring traceability, clear rationale, and impact assessment before implementation.
• Coordinates with product, engineering, and QA teams to align UX changes with development milestones and avoid late-stage design rework.
• Tracks and controls out-of-scope design changes, evaluates their potential impact, and communicates implications to relevant stakeholders.
• Participates in roadmap planning by identifying long-term UX opportunities through early research, aligning user needs with business goals and product strategy.
• Skilled in prioritizing features and recommending trade-offs based on cost-benefit analysis, user value, technical constraints, and timing.

• Familiar with requirement and task management tools such as Jira, CodeBeamer, and Microsoft Project, enabling effective tracking and cross-functional alignment.
• Capable of creating and maintaining clear UX documentation, including flows, wireframes, design rationales, and implementation notes for developers and testers.
• Strong communication and storytelling skills, able to explain complex UX logic and behavioral flows to both technical and non-technical stakeholders.
• Comfortable conducting design reviews, leading walkthroughs, and facilitating cross-team discussions to resolve design conflicts and ensure alignment.
• Able to work efficiently in cross-functional teams, contributing to sprint planning, backlog grooming, and iteration reviews.
• Leadership & Collaboration
• Demonstrates ownership of UX direction across feature domains, proactively identifying design opportunities and leading key initiatives from concept to validation.
• Acts as a design thought partner to product managers and engineers, ensuring user needs are considered in business and technical decision-making.
• Provides strategic UX guidance to align design efforts with long-term product vision and cross-functional roadmaps.
• Collaborates closely with UIUX designers, researchers, engineers, and system architects to ensure cohesive and implementable UX solutions across the infotainment ecosystem.
• Advocates for design quality by initiating and driving design critiques, cross-functional reviews, and early alignment with engineering constraints.
• Supports team capability by sharing design frameworks, reusable assets, and UX rationale, helping improve consistency and efficiency across the design team.
• Open to feedback and iterative collaboration, while confidently defending user experience principles and decisions based on data, standards, or usability validation.
• Driving Context Knowledge (Automotive Domain Awareness)
• Solid understanding of the driving context, user attention span, and environmental constraints in a moving vehicle.
• Familiar with automotive HMI standards and regulations (e.g., ISO 15005, AAM Guidelines, UN R121).
