TEAM
The Human System Integration team is developing the human machine interface (HMI), which helps ensure that drivers can use advanced driver assistance systems (ADAS) safely and securely. As ADAS replaces part of human cognition, judgment, and operation, we aim to promote mutual understanding between the car and humans through HMI and deliver safe, reliable mobility to more people in more places. HMI development is a stage where you can collaborate with diverse departments and translate ideas into concrete code through hands-on practice, and develop software that directly enhances the appeal of the vehicle.

WHO ARE WE LOOKING FOR?
Would you like to take on the challenge of developing HMI (Human-Machine Interface) control applications for next-generation advanced driver assistance systems? Our team develops applications that create information displayed on meters, head-up displays, and multimedia systems. This information is generated from diverse data collected by the vehicle to deliver new experiences to drivers. We welcome people who deeply understand cutting-edge AI technologies and are eager to tackle future HMI challenges. Leverage your solid coding skills and broad software development knowledge to drive implementation and evaluation as Proof of Concept (PoC). We seek people who not only possess technical expertise but also actively communicate with team members, shape owns ideas, and have the drive to see projects through to completion.

RESPONSIBILITIES:
• Design and implement next-generation HMI (Human-Machine Interface) control applications as proof-of-concept (PoC) prototypes
• Evaluate the application's functionality and the usability of the HMI by using simulators
• Share evaluation results clearly with team members and project stakeholders, incorporating their feedback and advice to drive subsequent improvements

MINIMUM QUALIFICATIONS:
• People with experience in machine learning workflows (data collection/preparation, preprocessing, model creation, detailed analysis, evaluation, deployment, and inference optimization)
• Experience programming in Python, C, or C++
• Proficiency and experience communicating in Japanese (JPL N1 or native level) for work, including written and verbal communication
• Logical thinking and explanatory skills to present challenges and solutions to stakeholders
• Currently enrolled in a master's program (or higher)

NICE TO HAVES:
• Experience conducting usability evaluations using tools such as driving simulators
• Experience in UX (user experience) planning and interactive design
• Experience developing and evaluating driver assistance or automated driving systems
• Knowledge of the latest trends in machine learning (large language models, foundation models, pre-training and efficient fine-tuning, multimodal Transformer architectures, etc.)
• Experience using machine learning frameworks such as PyTorch or TensorFlow
• Experience using modern cloud services such as AWS, GCP, Azure, and GitHub
