60 Acquire Data Scientist Jobs Hiring Near You

Job Summary:
Northern Trust is a globally recognized financial institution that has been in operation since 1889. They are seeking a Senior Data Scientist to develop software for data acquisition, analyze datasets, and build machine learning models while collaborating with various teams and stakeholders.
Responsibilities:
• 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 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
• May 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 some 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
• Solves complex problems
• Takes a new perspective on existing solutions
• Exercises judgment based on the analysis of multiple sources of information
• Impacts a range of customer, operational, project or service activities within own team and other related teams
• Works within broad guidelines and policies
