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
