• Communicate modeling results in business-friendly language to partners and department leadership by building PowerPoint presentations

• Deploy models for production into AWS SageMaker and work with our IT department to identify the necessary data feeds so models can produce inference

• Work with our UX designers to decide how model results will be shown in an application

• Monitor model accuracy over time and keep an eye out for model drift; retrain model when accuracy drops below agreed-upon threshold

• Periodically report back to partners on model performance

• Experience with unsupervised and supervised Machine Learning models (i.e. Decision trees, Naive Bayes, Clustering, Ranking, Classification) as well as Machine Learning concepts like boosting, dealing with imbalanced classes, train, test vs. validation set and overfitting

• Bonus: Experience with NLP concepts such as Named Entity Recognition, constructing Document-Term-Matrices, Topic Modeling and Text Classification

• Bonus: Experience with Model lifecycle management concepts such as model bias and drift, constructing data Labeling jobs for collection of 'golden dataset', and model deployment, monitoring and decommissioning in AWS SageMaker

Soft skills

• Customer Centric – You put the customer/player at the center when designing new offerings and processes.  You understand how decisions and work impact the player.

• People Analyst – You understand that your work contributes to improving people's experiences, not predict when a machine is going to break down

• Learner – You are a regular on Stack Overflow, know how to take apart a Vignette and are always looking for a new project that allows you to put that cutting edge technique to good use you read about last month

• Documentation Expert – You know just the right level of documentation to help yourself and the person who takes over after you understand what you did, when and why
