Description

The Apple Ads team is seeking a strategic, hands-on Machine Learning Engineer to drive innovation across a modern, large-scale platform.

You will design, build, and operate real-time ML systems and large-scale data pipelines that power end-to-end prediction and decisioning—spanning personalization, retrieval/ranking, allocation, and optimization—while upholding strong reliability, privacy, and safety standards. You’ll define and execute an innovation roadmap; productionize models with robust CI/CD, feature stores, and streaming infrastructure (e.g., Kafka/Spark/Flink); and run A/B experimentation. You will lead performance tuning, calibration, and drift detection to deliver measurable improvements in product quality, user experience, latency, and cost.

This role rewards ownership from architecture through monitoring and SLAs, with influence across adjacent areas such as recommendations, response prediction, and experimentation tooling.

Minimum Qualifications

• 4+ years of experience building machine learning capabilities across many different product areas at scale

• Strong proficiency in Java, Python, or Scala for algorithm and system development.

• Experience with distributed systems and big data frameworks such as Spark, Kafka, Hadoop, or Flink.

• Solid understanding of data structures, algorithms, and system design principles.

• Expertise in working with relational databases (PostgreSQL, MySQL, Oracle) and NoSQL/Cloud storage (S3, GCS, etc.).

• Familiarity with CI/CD workflows, cloud environments, and containerized deployments.

• Knowledge of data validation, cleansing, and quality assurance practices.

• Understanding of statistical methods, A/B testing, and online experimentation frameworks.

• Prior experience working with machine learning platforms or real-time recommendation engines is a plus.

• BS or MS in Computer Science, Software Engineering or related technical fields.

Preferred Qualifications

• 7+ years of experience building machine learning capabilities across many different product areas at scale.

• Background in Advertising systems.

• Hands-on experience with service reliability engineering (SRE) and SLA monitoring.

• Contributions to open-source algorithm frameworks or data processing tools.
