Senior Data Scientist II (ML)

Senior ML Scientist II

May Mobility is experiencing a period of significant growth as we expand our autonomous shuttle and mobility services nationwide. We are seeking talented data scientists and machine learning engineers to develop automated methods for tagging data collected by our autonomous vehicles. This will enable us to generate valuable insights from our data, making it easily searchable for triaging issues, creating test sets, and building datasets for autonomy improvements. Join us and make a crucial impact on our development and business decisions!

Responsibilities

• Design, implement, and deploy state-of-the-art machine learning models for analyzing multimodal data to generate searchable metadata and facilitating downstream engineering workflows such as quick issue triaging.
• Curate high-quality datasets for evaluation and training to ensure model robustness, performance, and coverage.
• Research and implement novel techniques for sequential feature extraction, weak supervision, and self-supervised learning to efficiently handle long-tail events and continuously improve labeling data quality.
• Establish and maintain frameworks for model validation and performance monitoring to drive continuous improvement.

Skills

Success in this role typically requires the following competencies:

• Expert proficiency in designing and implementing deep learning architectures for multimodal data for offline analysis.
• Strong understanding of data labeling best practices, label consistency, and performance metrics specifically relevant to large-scale auto-tagging accuracy and dataset curation.
• Expertise in machine learning, with hands-on experience in the design, training, and evaluation of a wide range of algorithms.
• Awareness of the latest advancements in the field, with the ability to translate innovative concepts into practical solutions for May.
• Excellent problem-solving skills with a meticulous approach to model architecture and optimization.

Qualifications and Experience

Required
