Senior Platform Software Engineer

People at Apple don't just build products. They craft the kind of experience that has revolutionized entire industries. The diverse collection of our people and their ideas inspire innovation in everything we do. Imagine what you could do here! Join Apple, and help us leave the world better than we found it. Core Data and Intelligence (CDI) is the central data, AI, and machine learning engineering team in ASE Media. We build the primitives other teams rely on: privacy-compliant data collection, canonical datasets, AI and machine learning building blocks, and the visualizations that turn them into decisions. That work shows up across Apple. It is a signal for Music recommendations, a report on the engagement of a new TV+ feature, and the Average Revenue Per User we share with developers. We partner with client and server teams to source data and ensure collection meets Apple's high privacy standards. CDI also leads privacy engineering within ASE. Apple Services Engineering powers App Store, Apple TV+, Apple Music, Apple Podcasts, Apple Books, Fitness+, the iTunes Store, and more. The Data Engineering Platform (DEP) is how CDI does that work at scale. DEP builds an opinionated data engineering ecosystem that accelerates data and machine learning engineers. It includes spec-driven development, data quality, AI-driven workflows, cloud portability, CI/CD, integrated privacy and compliance, and scaled operational tooling. We are looking for a Senior Platform Software Engineer to build and evolve the foundations of DEP. You will work across the full depth of the stack, from the command an engineer types to the infrastructure running in production. You will build foundational developer and platform systems, take direct responsibility for critical production services, and establish engineering patterns that scale across DEP.
