Open Position: HMI Specification & UX Integration Specialist (m/f/d) Location: Stuttgart

Responsibilities

• You will be responsible for the operational support, adaptation and implementation of UX/UI/HMI concepts up to series-production maturity with a special focus on Android Automotive HMI. Your duties include, but are not limited to:
• Take technical ownership of design and interaction concepts and ensure consistent implementation that meets user and brand goals.
• Assess concepts for feasibility in a series-production Android Automotive environment; identify technical, safety or regulatory adaptation needs and initiate required changes.
• Create and maintain implementation and handover specifications (screens, flow & state charts, implementation notes, Car App templates) for development partners.
• Prepare prototype adjustments, wireframes and mockups for validation and support implementation in Android development environments.
• Closely accompany the implementation phase with internal teams and external development partners; coordinate feedback loops and prioritization.
• Support validations, usability checks and release reviews; track open items through to series release.
• Document changes, maintain specification baselines and present results in workshops and review meetings with stakeholders.

Basic Qualifications

• Degree in Interaction/UX Design, Media Informatics, Industrial Design, Computer Science with a UX focus, or equivalent.
• Experience specifying and overseeing complex user interfaces (UI/HMI), preferably in the automotive domain.
• Confident use of common HMI/design tools (Figma, Sketch, Adobe XD, Axure, InVision, etc.); ability to adapt prototypes and mockups.
• Practical experience creating flow/state charts, wireframes and technical handover documents.
• Experience collaborating with software development teams and external partners; familiarity with agile processes and tools (e.g., Jira, Confluence) is an advantage.
• Structured, result-oriented and communicative working style; strong moderation and alignment skills.
• Reliable and independent work approach.
• Affinity for digital topics and interest in automotive series development.
• Very good German and good English skills.
• Class B driving license desirable.

Additional HMI & Android Automotive Requirements

• Understanding of input methods and UX patterns for cars: touch, rotary/knob, steering-wheel controls, voice interaction — design for glanceability and low driver distraction.
• Experience with multi-display / cluster vs. head-unit layouts and cross-display coordination (infotainment, instrument cluster, HUD).
• Knowledge of platform constraints and performance optimization: GPU/CPU limits, memory constraints, compositor/SurfaceFlinger behavior, display composition, refresh rates and latency mitigation.
• Experience with localization/internationalization, accessibility (e.g., screen readers, high-contrast modes) and scalability across resolutions and languages for series products.
• Hands-on skills in Android development and debugging: Android Studio, Kotlin/Java, Gradle, ADB, logcat, systrace/perfetto, and head-unit emulator testing.
• Experience with app vs. system UI integration on AAOS: differences between system-level HMI components and third-party car apps, lifecycle and permission/security models.
• Understanding of OTA/update flows, secure boot implications, and how updates affect HMI behavior and feature rollout.
• Awareness of automotive standards and processes (ISO 26262 functional safety, ISO/SAE 21434 cybersecurity, Automotive SPICE) and how HMI requirements integrate into safety/security workflows.
• Practical knowledge of integration and verification workflows (HIL/MIL/SIL where applicable, system integration, in-vehicle validation) and automated testing strategies for HMI on AAOS.
• Comfortable working across multidisciplinary teams: systems engineering, SW/HW development, QA, validation, product management and suppliers.

Tools & Workflow (typical)

• Design & prototyping: Figma, Sketch, Adobe XD, Axure.
• Requirements & traceability: Jira, Confluence, DOORS (or equivalents).
• Android toolchain: Android Studio, ADB, Android Emulator.
• Debugging & profiling: logcat, Systrace, Perfetto, GPU profiler tools.
• CI/CD & build: Jenkins/GitLab CI, artifact repositories and flashing pipelines.
