Our technology powers ads and sponsorships across Apple Services, including the App Store, Apple News, and MLS Season Pass.

Collaborate with cross-functional teams across engineering, infrastructure, and product to scale models to production

Participate in designing and running large-scale experiments to validate new model architectures and learning strategies

Preferred Qualifications

MS or PhD, or equivalent experience, in Computer Science, Machine Learning, Artificial Intelligence, Information Retrieval, or a related field.

Great foundation in information retrieval, including query-document matching, embedding-based ranking, and learning-to-rank algorithms is a plus

Minimum Qualifications

6+ years of experience applying machine learning and statistical modeling at scale, preferably in ad tech, recommender systems, or web-scale search/retrieval

Deep experience with neural network architectures (e.g., Transformers, DNNs, RNNs) and training pipelines using TensorFlow, PyTorch

Practical understanding of reinforcement learning, explore/exploit strategies, and bandit-based optimization

Experience working with high-volume data pipelines, A/B testing infrastructure, and performance measurement at scale

Proficient in Python and familiar with SQL, Scala, or Java for production environments

Ability to translate abstract ideas into concrete, high-impact solutions

Bachelor's, or equivalent experience, in Computer Science, Machine Learning, Artificial Intelligence, Information Retrieval, or a related field.
