Machine Learning Engineer Platform - iCloud Mail Intelligence
Are you passionate about applying your deep understanding of machine learning technologies
and data platform skills in creative ways? Apple's iCloud Mail Intelligence Platform team is
looking for an excellent Machine Learning Engineer that can continuously innovate on the
iCloud experience across Mail, Calendar, and Contacts.
The team is responsible for building groundbreaking ML infrastructure that supports intelligent experiences for hundreds of millions
of users worldwide.
Description
As a machine learning engineer, you will be focusing on:
Leveraging existing AI/ML infrastructure, build new platform services and be responsible for building an end to end machine learning based product solution for improving iCloud Mail experiences.
Working with large volumes of data; extracting and manipulating large datasets using tools such as Spark SQL, command line and scripting languages.
Collect ongoing qualitative and quantitative feedback from the user population and iterate based on the findings.
Building high-performance, scalable and extensible REST based services for enhancing Mail consumer experience.
Design database schemas, write queries, and optimize database performance.
Consider joining a small team writing the software which provides mail services to iCloud customers. We are looking for a very capable engineer who has a strong background in building high-performance, scalable and extensible systems using big data technologies. In addition to crafting efficient, testable, easy-to-maintain code, you recognize the importance of writing functional specifications and design documents. Quality is number one in your mind, and you flourish with building comprehensive unit and end-to-end tests, not only for features you build but also for existing features that need more testing. In this highly transparent position, the successful candidate will enhance existing mail systems while collaborating with multi-functional engineering teams, and also implement new customized mail experiences, in addition to preventing abuse of the system.
Responsibilities:
Leverage existing Apple AI/ML infrastructure and build new platform services that
standardize and accelerate ML feature development across Mail, Calendar, and Contacts
Design, develop, and deploy end-to-end machine learning applications and models that
improve the iCloud experience
Work with large volumes of data; extract and manipulate large datasets using tools such as
Spark, SQL, command line, and scripting languages
Build high-performance, scalable, and extensible services for delivering ML models and
features into production
Establish and apply standards for evaluation, testing, and model observability
Collect ongoing qualitative and quantitative feedback from the user population and iterate
based on the findings
Partner with multi-functional engineering teams to enhance existing systems and implement
new ML-driven experiences across Mail, Calendar, and Contacts
Preferred Qualifications
5+ years of ML engineering experience (or equivalent depth) with a track record of technical
leadership on large-scale ML systems or ML platforms that standardize workflows across
multiple teams

ML pipelines: data processing, feature engineering, training, serving, and monitoring
Experience with large-scale distributed systems including data processing, event-driven
architectures and both real-time and batch inference
Strong programming skills in one or more production languages (e.g., Python, Java, Scala,
Kotlin, Go)
Demonstrated ability to drive projects independently from problem definition to production
Deep understanding of predictive modeling and machine learning algorithms across
supervised and unsupervised learning
