About the Team/Role
Our Team: The Risk Data Science team is part of the Global Risk Solutions and Strategy group. We are a fast-growing team optimizing risk solutions and models, and we are a key function to help enable WEX’s strategic objectives. The Risk Data Science team uses a variety of advanced methodologies (including machine learning and statistical frameworks), a wide suite of data types, and modern technologies to develop solutions to inform decision making. One of the areas of our team helps the firm identify and measure credit risk to proactively manage the risk throughout the client’s life-cycle. As such, you will not only be working with the latest data and machine learning technologies and algorithms, you will be working in a dynamic environment alongside our stakeholders and domain experts to build models and drive better decision-making.
Our Company: WEX is a fast-growing multinational payments company based in beautiful Portland, Maine. WEX headquarters is situated in the heart of Portland amongst some of the best restaurants in the country and overlooking the ocean and lighthouses. When you are here, you know you are in Maine. We have generous paid time off and paid volunteering time, not to mention great benefits and a culture that values diversity and inclusion.
You are driven to do great work. You love learning new things and solving complex problems with data tools and algorithms. You believe that communication and relationships are key to success alongside your data and machine learning prowess.
Partner with stakeholders to develop data-driven methods to measure and monitor credit risk across the firm’s products and services.
Leverage understanding of credit processes (including credit origination, portfolio monitoring, credit line assignment, loss forecasting, and others) to design flexible, scalable, and automated modeling solutions.
Utilize advanced statistical and machine learning methods and technologies to deliver best-in-class models to support risk decision making
Develop code and automated processes to manipulate high volume, high dimensional data sources to extract informative patterns, perform exploratory analyses and engineer useful features
Keep abreast with emerging trends in lending, macroeconomic environment, and machine learning to identify new opportunities and tools to solve problems and drive innovation
Synthesize data science findings into actionable insights and articulate them to the appropriate stakeholders
Proactively identify and communicate challenges, opportunities, and risks associated with project work to ensure timely completion of the entire product
