Job description

Job Description: Position Summary We are seeking a detail-oriented and technically versatile Vehicle Software Integration Test Engineer to support Human-Machine Interface (HMI), User Experience (UX), and User Interface (UI) validation for next-generation vehicle systems. In this role, you will serve as a bridge between hardware and software domains, working hands-on with vehicles and Test Development Kits (TDKs). You will utilize debugging tools, perform software updates, and support pre-production HMI quality validation initiatives. The successful candidate will play a critical role in ensuring test environments are properly configured and capable of executing reliable HMI validation testing.

Key Responsibilities

HMI Validation & Testing

• – Set up validation requests for HMI, UX, and UI features across vehicle infotainment systems using TDKs and vehicles.
• – Perform HMI validation testing and report quality assurance concerns.
• – Validate software implementations against design releases.

Vehicle & TDK Configuration

• – Utilize in-house diagnostic tools and Android Debug Bridge (ADB) to debug and configure testing environments on vehicles and TDKs.
• – Ensure appropriate software levels are flashed and required Diagnostic Identifiers (DIDs) are enabled for HMI testing.
• – Set up vehicles and TDKs with appropriate hardware and software configurations to evaluate prototype designs and HMI display content.

Software & Simulation Support

• – Collaborate cross-functionally with software teams to set up and execute Python scripts enabling simulation support for:
  • HMI testing
  • Software download processes

Hardware & Software Integration

• – Support hardware and software integration efforts across embedded control units (ECUs).
• – Facilitate seamless communication between hardware and software systems.
• – Work with prototype hardware configurations to support testing activities.

CAN Network Support

• – Utilize CAN hardware for feature signal simulation.
• – Record CAN information to support deployment and monitoring of vehicle network signals.
• – Send CAN messages and configure system parameters using in-house tools.

Troubleshooting & Root Cause Analysis

• – Break down complex system issues into fundamental root causes.
• – Troubleshoot concerns spanning both hardware and software layers.
• – Retest systems to confirm resolution and readiness for HMI testing.
• – Review ECU configurations and root-cause issues impacting HMI validation.

Documentation & Process Improvement

• – Document software methodologies, processes, and procedures.
• – Create and maintain documentation related to vehicle and bench update processes.
• – Simplify test procedures and configuration processes through analytical problem-solving.

Additional Responsibilities

• – Maintain a strong understanding of vehicle architecture and communication systems.
• – Adapt to changing priorities, evolving test environments, and dynamic project requirements.
• – Support prototype hardware integration, including ECU swaps and wire harness modifications when required.
• – Occasional travel may be required between Mexico and California.
