At Apple, we work every day to create products that enrich people’s lives. Our Advertising Platforms group makes it possible for people around the world to easily access informative and imaginative content on their devices while helping publishers and developers promote and monetize their work. Today, our technology and services power advertising in Search Ads in the App Store and Apple News. Our platforms are highly-performant, deployed at scale, and setting new standards for enabling effective advertising while protecting user privacy. Ads ML Platform team is looking for a Machine Learning Engineer to build the next generation of software platform and systems to advance algorithms that connect millions of global users to content from publishers and developers. Your work will drive the experimentation and development of machine learned algorithm at scale. You will build sophisticated systems essential in the end-end development of predictive algorithms, from experimentation to productization. You will design and engineer tools that support the end-end ML lifecycle of raw data exploration, feature extraction, automated computation of feature values and for serving on-line prediction that reacts to real-time signals, while preserving privacy of our customers.

Key Qualifications

  • Extraordinary software engineering skills designing and building complex large-scale and distributed software systems in cloud computing environments like AWS
  • Exposure to machine learning platform, methodology, lifecycle and A/B testing
  • Fluency in programming languages like Java, Scala, Python and SQL
  • Familiarity with data-oriented workflow orchestration frameworks like Airflow, Kubeflow, etc.
  • Experience with event stream processing (ESP) technologies like Spark Streaming, Kafka, Flink or equivalent
  • Proven ability to implement and extend highly performant, resilient and reliable backend systems
  • Experience with backend object stores, automated data pipelines, cloud-native data storage and processing frameworks
