The MTA delivers subway, bus and commuter rail service, as well as tolled bridge and tunnel operations, in the New York City metro area. It is the largest public transportation provider in the Western Hemisphere, with millions of daily riders and a multi-billion-dollar budget. Delivering service and maintaining our infrastructure is increasingly data-driven, and so data scientists have become central to the MTA’s operations and decision-making. As a member of the Data & Analytics team, you will work on a dynamic, growing team tasked with helping to define and achieve the MTA’s strategic priorities and address its most pressing challenges. You will get the experience of seeing your work become public data and have it influence critical decisions that affect millions of New Yorkers.

Our work combines new approaches and algorithms with a deep knowledge of our operations to deliver deeper insights into our performance. Our outputs are used by a wide array of people: from the MTA Board and senior execs to front-line managers and our open data customers. If you would like to use your programming skills to work on complex problems to improve public transit in NYC, then we’d like to talk to you.
The incumbent will help lead member of the team that designs, builds, tests, and delivers end-to-end, automated data pipelines over complex on-premises and off-premises platforms.

They will use languages such as SQL, Python and R and relational database tools such as Oracle, Postgres, and SQL Server to analyze large datasets, build new ones, and design overall data architectures. They will carefully document all work and work closely with colleagues to define needs, problem-solve, support the overall team agenda, and build relationships throughout and at all levels of the agency. They will have to be able to quickly learn the unique features, data constraints and business needs of any part of the MTA. In addition, unlike other data engineering roles, they will support the entire downstream pipeline process and, occasionally, end-users of the data products. In general, they will have to support the MTA’s strategic goals to build data systems and processes that are well-structured and sustainable.
