1,845 jobs for "Senior Support Engineer"

At Apple, extraordinary products begin with a deep understanding of the people who use them. Our Korea Channel Sales team leverages data to shape business strategy, optimize customer experiences, and drive growth across channels and partners.
As a Senior Data Engineer & Scientist, you will build the data infrastructure that connects fragmented data sources across the business - and apply that foundation to generate insights, run experiments, and develop AI-driven solutions. This dual role is ideal for someone who can architect reliable data systems and, with that same depth, design the experiments and models that turn data into business decisions.

Description
In this role, you will own the full data lifecycle - from pipeline architecture and data modeling through to statistical analysis and AI-driven insight generation. You will work closely with cross-functional teams spanning marketing, business operations, partner management, and engineering.
Early on, you will focus on standing up data infrastructure: building ingestion pipelines, automating dashboards, identifying data gaps, and ensuring data governance and compliance. As the foundation matures, you will shift toward data science - designing experiments, generating customer insights, and applying machine learning to optimize initiatives for sales growth.
You will also contribute to the development of data platforms that enable seamless collaboration with external and internal partners, and help scale analytics capabilities across the organization.","responsibilities":"Design, build, and maintain scalable data pipelines and automated reporting infrastructure to support business priorities across the Korea Channel Sales organization
