ABOUT THIS JOB

Platform engineers strike a balance between precision and disruption, between reliability and innovation. Nielsen is a tech company backed by over a century of forward momentum to show the world what’s next—and we couldn’t do it without our platform engineers.

Nielsen Media is the market leader in content ratings across virtually all entertainment platforms including local and national TV, streaming, digital advertising, and more. In the role of Data Engineer on the Identity Team, you'll be responsible for developing the systems that estimate the audience consuming the content. This effort deals with massive data sets, demanding keen focus on both performance and design.

• Review and refine the fundamental Data Engineering and SRE practices in the Identity platform and help define a standard for use around Nielsen.
• Mentor other platform team members to increase their technical and soft skills

• You have a genuine passion for data engineering at scale and absolutely love learning new technologies. You don’t just want to blindly use platforms and libraries; instead you have a desire to tear them apart and figure out how they work inside. You love scaling and optimizing and seeing just how far or how fast your projects can go. You see all of the building blocks in the community as legos and want to use them to build innovative new solutions at a faster pace than ever.

• Apache Spark (spark-sql, graphframes)
• Trino/Presto
• Airflow 2.x
• Python

• 5+ years of experience in a MLOps, Data Engineering, DBA or Database Developer role leading critical projects of high complexity.
• Capable of proposing/evaluating data system architectures for high-scale projects.
• In-depth knowledge and experience implementing core big data concepts and tools spanning source control, CI/CD, Infrastructure as Code, monitoring, alerting, logging.
• Deep knowledge of Apache Spark is a must - spark-sql internals specifically is a significant plus.
• Proficiency in AWS, with strong knowledge of S3, KMS and IAM.
• Experience training and mentoring junior team members.
• Experience with Apache Spark graphframes is a plus.
