Data Scientist Job Description


The Data Science Lab at Northern Trust performs data science research and develops custom prototypes to problems that


1) are not adequately addressed by available commercial solutions,


2) enhance the customer and/or internal partner experience and


3) provide Northern Trust with a competitive advantage. We also serve to inspire and empower applied data science practitioners by facilitating high-quality data science education and collaboration within Northern Trust as well as with top universities and research institutions.


 As a member on the team, a candidate will be expected to:


• Develop software, typically in Python, to independently acquire data from disparate sources (databases, files, APIs, etc.) and combine them into appropriate training , validation and testing datasets


• Analyze raw datasets using descriptive statistics, working directly with domain experts to understand the meaning of data fields


• Build unit tests, data quality checks and data pipelines to ensure that algorithms use trusted data


• Develop and maintain an understanding of many algorithms across supervised learning, unsupervised learning, reinforcement learning and time series analysis


• Propose and develop machine learning ensemble methods that exhibit the best out-of-sample characteristics possible given the input dataset


• Utilize expertise in machine learning algorithms to tune algorithms using available hyper-parameters and carefully select feature subsets


• Discover biases or leakage in datasets and ensure that train/test splits reflect realistic expectations of real world performance


• Run large scale (either in parallel and/or distributed) training and inference jobs on private or public cloud infrastructure


• Present findings to internal and external customers using both data science language (F1 scores, regression error, statistical significance, etc.) as well as business domain specific language gained from experience analyzing the data in scope.


• Provide guidance to other software development teams as Data Science Lab prototypes are engineered for full production environments


• Work across multiple projects in a fluid environment where work is required across the full research lifecycle from forming a hypothesis, acquiring data, and developing ETL-style software to presenting findings.


• Plan and execute data science training sessions and hackathons


• Work with external parties (vendors, universities, etc.) to incorporate new techniques and tools into the data science lab
