Principal Data Scientist I

Charter Communications • Stamford, CT, United States • $200k - $250k / year • 3w ago

JOB SUMMARY

Responsible for leading the development of data-driven solutions to Charter's business problems. Utilizes analytical, statistical, and programming skills to clean, aggregate, and analyze large data sets and interpret results. This position requires a strong command of statistical techniques and machine learning algorithms, as well as a demonstrated practical ability to determine where to invest time, synthesize actionable findings across diverse assignments, and present findings to audiences with diverse agendas and varying levels of technical expertise. This role will be responsible for the delivery of insights and analytics on the trends and causes of quality-of-service and service-rate fluctuations in our Internet and Video products. Promptly identifying problematic network equipment, configuration, maintenance, and other controllable drivers while separating out the non-controllable elements such as usage and weather, resulting in insights delivered to internal stakeholders to resolve identified issues.
Will require a range of applied analytic techniques, from simple crosstabs to state-of-the-art AI/ML algorithms to measure the causal impact of drivers. In particular, we are expanding our approaches and techniques to include the fast-developing field of Causal AI. These techniques will be applied against a set of large and growing data - over 30 million rows of 100 columns per day, and growing. Compute resources will include high-end relational data warehouse and cloud-based GPU-heavy compute for AI/ML. This role will be considered an intellectual co-owner of the algorithms and procedures methods used to derive causal insights from observational data. Works with R&D and development (analytic requirements) against backlog of desired features. One will perform R&D on and apply these techniques to real-world problems in order to further refine and develop the methods and implementation of them. In addition, this role will be the lead applied analyst on the team, responsible for reviewing work product, providing constructive and coaching feedback to junior team members, and delivering key results to senior stakeholders in a clear, polished, and professional manner.

MAJOR DUTIES AND RESPONSIBILITIES

Actively and consistently support all efforts to simplify and enhance the customer experience
Plan and lead the complete analytics life-cycle for problem solving, including: requirements gathering, problem formulation, data grooming, data exploration, model prototyping, model validation, and algorithm productionalization
Leverage consultative experience delivering insights on large structured data to senior operational executives with strong communications skills (verbal, written, powerpoint)
Perform mid-level and advanced analytics using a range of techniques from basic (pivot table) to advanced (Causal AI tools and models)
Troubleshoot, debug, solve problems where the analytic approach, model, or tool is not performing as well as needed, and lead the exploration of vendors in the marketplace that can meet this need, enabling buy versus build
Participate in reviewing vendor tools and products that might be fit for our needs; consistently keep up-to-date in the latest market and academic developments in Causal AI
Plan effectively to ensure analytics products are flexible, modular, and contain reusable code base
Identify future technical needs of assigned projects to continue to grow capabilities of organization
Coordinate technical activities across projects and the organization
