Data Scientist I - Space Optimization

Responsibilities

H-E-B's Corporate Planning and Analysis Team develops and maintains budgets and financial systems while providing current, reliable financial data, analysis, and technical information.As a Data Scientist I, your archetype is an ML / AI Expert + ML Engineer. Your passions include understanding best-in-class AI techniques, customizing algorithms to create HEB-unique differentiators, integrating AI techniques into H-E-B reusable end-to-end ML pipelines, refactoring DS algorithms and models based on the target platform to maximize platform efficiency, and optimizing the end-to-end learning pipeline (from exploration, development, building, and deploying to endpoint systems).Once you're eligible, you'll become an Owner in the company, so we're looking for commitment, hard work, and focus on quality and Customer service. 'Partner-owned' means our most important resources--People--drive the innovation, growth, and success that make H-E-B The Greatest Omnichannel Retailing Company.Do you have a:HEART FOR PEOPLE... willingness to take a break from algorithmic thinking / detecting to translate and share your findings with a variety of business customers?HEAD FOR BUSINESS... understanding of best-in-class AI techniques?PASSION FOR RESULTS... ability to generate business-valued questions and data-driven solutions?We are looking for:- someone who constantly acquires and demonstrates in-depth expertise across end-to-end ML / AI lifecycleWhat is the work?
