The Sr Data Scientist executes statistical and mathematical analyses to support business decision-making. This role supports artificial intelligence/machine learning (AI/ML) in a deployed production environment. They are experts in the field of Data Science. Consequently, the Sr Data Scientist proactively works with cross-functional teams to seek and understand the business/domain context of potential problems that may be solved using ML. They present data science solutions to stakeholders in an iterative fashion. The Sr. Data Scientist works with Associate Data Scientists and Data Scientists in converting a business problem into an ML problem and kickstarting foundational work including data exploration, feature engineering, basic hypothesis testing, and creation of baseline models. They create the model feasibility document in close collaboration with the Data Scientists and Sr Data Scientists. The Sr Data Scientist may have direct reports including Associate Data Scientists and Data Scientists.

This position is remote which means the work can be completed from anywhere in the United States except Hawaii or United States Territories.

ESSENTIAL DUTIES AND RESPONSIBILITIES

As a Sr Data Scientist, you will be expected to:

Work with Associate Data Scientists and Data Scientists in researching data sources, data cleansing, feature engineering, and creating baseline models

Independently manage multiple data science model development/projects

Collaborate and engage with various cross-functional stakeholders to ensure close coordination between data science and business stakeholders including the product management team

Provide full ownership of the model development from inception to implementation including the machine learning pipeline, documentation, model drift, and remodeling strategy

Mentor the Associate Data Scientists and Data Scientists in data science knowledge and their interactions with other stakeholders

Coordinate with the ML team, anticipating deployment issues upfront, setting the stage for resource requirements, and ensuring the success of model deployment and retraining

Take and delegate ownership of critical tickets or issues faced by business stakeholders as assigned by the Lead Data Scientist or Director of Data Science 

Read and independently navigate through extensive codebase with a focus on troubleshooting, debugging, and/or improvement of code

Contribute to coding standards and coding conventions and proactively participate in enforcing sound coding practices across the data science team

Create and maintain documentation of the ML models, data sources, and methodology 

Assist in the creation of feasibility documents 

Proactively participate in the core team processes including R&D, recommending, and implementing process improvements or new methodologies

Share knowledge with other various teams and members by presentation at periodic internal team sessions/workshops

Guide usage of development methodologies (Scrum, Kanban, etc.)  and assist in their implementation in the group projects by deciphering details including features, tasks, estimates of efforts and timing, etc.
