Full Job Description
You will join a team of world-class engineers with an appetite for applying leading-edge technologies to deliver extraordinary experiences to our customers, and collaborate closely with the business to deliver relevant data and insight that informs our strategy and decisions.
You should have 1-4 years of experience in software engineering roles, ideally within the ads or media space. You will have a strong understanding of scalable approaches and thrive working in Agile environments. The ability to be a good, standout colleague under tight deadline constraints is key to success. We will calibrate the level and scope to your experience.
Description
At Apple Ads, we are building the next generation of privacy-focused advertising capabilities. As part of the data organization, we work at the cutting edge of data engineering, machine learning, and privacy at Apple's scale. We are constantly developing data products to provide amazing user experiences and to drive value for developers and publishers. As a member of the Data Org, you will:
- Engineer secure, scalable data and machine learning systems across real-time, near-real-time, and batch execution contexts using Spark, Kafka, Iceberg, and beyond
- Own the design and delivery of core components - from pipeline architecture to ML model development, training, and deployment - including support for privacy-preserving, mission-critical infrastructure
- Drive reliability, performance, and efficiency improvements across your systems, including schema changes, backfills, and the experimentation and testing infrastructure (e.g. A/B testing) needed to validate them
- Apply a strong understanding of the intersection between business, analytics, and engineering, with a proactive focus on reusable, efficient solutions
- Use LLMs and AI coding agents (e.g. Claude, Gemini) daily to accelerate implementation, testing, and debugging - continually validating every result for correctness, privacy, and cost
- Collaborate with a team of world-class engineers and product managers; grow through code and design reviews, and mentor others as you gain seniority
- Contribute to on-call, monitoring, and continuous reliability and efficiency improvements; more senior engineers help lead incident response and root-cause analysis
- Work effectively in a rapidly changing, sprint-based Agile environment, and contribute to a culture that emphasizes reliability, resiliency, extensibility, scalability, and productivity. We are one team, nurturing each other's growth and supporting each other in delivering for our customers and Apple
Minimum Qualifications
1-4 years of industry experience building scalable data pipelines and machine learning systems, or other distributed software, at scale
Strong computer science and software engineering fundamentals
Proficiency in modern programming languages such as Rust, Python, Java, or Scala
Experience with distributed systems and data processing technologies (e.g. Spark, Kafka, Flink)
Experience building and scaling systems on premise and in the cloud
Solid understanding of data structures, algorithms, and system design principles
Ability to communicate effectively with cross-functional technical and non-technical teams
Hands-on experience using LLMs (e.g. Claude, Gemini) in daily engineering work - for code generation, review, debugging, test writing, agentic loops, and evaluation systems- to continually improve software engineering skills and velocity
Excellent collaborative skills
BS/MS in Computer Science, Software Engineering, Distributed Systems, or a related field
Preferred Qualifications
Experience with NoSQL datastores (e.g. Cassandra, Keyspaces, ElastiCache)
Experience with lakehouse and Iceberg table formats
Experience with anomaly detection
Experience with A/B experimentation frameworks
History of driving reliability, efficiency, or cost improvements, and mentoring other engineers
Comfortable working in a rapidly changing environment with ambiguous requirements
Prior experience in the advertising industry is a huge plus
