Role Description:
As a Machine Learning Engineer II, you will be responsible for developing production-grade Machine Learning systems, from models to features and pipelines. You will own the design and delivery of ML systems, from initial idea generation and collecting business requirements from product stakeholders to implementation. You will work closely together with the other Machine Learning Scientists and Machine Learning Engineers in the Intent Discovery track as well as with Data Engineers, Software Engineers and Product Managers.
Key Job Responsibilities and Duties:
Develop production-grade ML systems, from models to features and pipelines, accounting for reliability, scalability, real-time requirements, monitoring, and retraining.
Build readable and reusable code, applying code quality best practices and using standard libraries. Choose the right technology or coding methodology and refactor and simplify code when necessary.
Take full ownership of services end-to-end by actively monitoring system health, performance, and business impact. Ensure the relevant service level objectives (SLOs) are met.
Combine innovation with reuse by abstracting ML/AI concepts from one application to a generalized framework, including leveraging published research, open-source technologies, and previously-developed products at Booking.
Be responsible for business-related data governance processes, technical implementation, and maintenance of data processing services and storage systems, as well as ML governance processes.
Evaluate possible architecture solutions considering business and technology requirements.
Contribute to the internal ML/AI community by sharing knowledge and participating in internal ML programs.
Continuously evolve your craft by keeping up to date with the latest developments in ML/AI and related technologies and upskilling as needed.
Qualifications & Skills:
Masters, PhD, or equivalent experience in a quantitative field (Computer Science, Mathematics, Engineering, Artificial Intelligence, etc.).
Minimum of 3 years of experience as a Machine Learning Engineer or a similar role, preferably with products that impact a large customer base.
Strong working experience in one or more general purpose programming languages, including but not limited to: Java, Python or Perl.
Experience with big data processing frameworks such as , Pyspark, Apache Flink, Snowflake or similar frameworks.
Experience with cloud frameworks like AWS sagemaker for training, evaluation and serving models using TensorFlow, PyTorch, or scikit-learn.
Deep understanding of machine learning algorithms, statistical models, and data structures.
Excellent communication and collaboration skills to work effectively with diverse crafts such as engineering, UX, and product management.
Experience with reinforcement learning and multi-armed bandit techniques is a strong plus.
(Nice to have) Experience with experimental design, A/B testing, and evaluation metrics for ML models.
