Pyyne is seeking a Senior Data Scientist with experience building and deploying statistical and machine learning solutions to work as a consultant out of our Latin American Office. This is a high-impact role for Pyyne as we begin a new engagement with a large US-based e-commerce retailer, and this is the first technical role on the project.

A successful candidate in this role will partner with a Pyyne Project Manager and the client's head of data to turn business questions into models and analyses that stakeholders can act on.

Key Responsibilities

• Explore, clean, and validate data from multiple sources, building reliable datasets and features for analysis and modeling.
• Design, train, and evaluate statistical and machine learning models, choosing the simplest approach that solves the problem.
• Design and analyze experiments (for example A/B tests) and define metrics that measure business impact.
• Work with the client's data and engineering teams to move models and analyses into production and keep them monitored over time.
• Write clean, tested, reproducible code and document assumptions, methods, and results so others can build on them.
• Work closely with team members to keep progress visible and raise risks early.

Must Have Skills

• 4+ years of professional experience as a Data Scientist or in a comparable applied machine learning or advanced analytics role
• Strong Python (pandas, scikit-learn, or equivalent) and SQL
• Solid foundation in statistics and machine learning, including model selection, validation, and experiment design
• Track record of taking analyses or models from exploration to something stakeholders actually use, and explaining results to non-technical audiences
• Advanced English, spoken and written, for daily collaboration with client stakeholders

Nice to Have Skills

• Experience in e-commerce, retail, or manufacturing use cases such as demand forecasting, pricing, or customer analytics
• Experience deploying and monitoring models in production (MLOps) on a cloud platform such as AWS, GCP, or Azure
• Familiarity with modern data stack tools such as dbt, Snowflake, BigQuery, or Databricks
• Experience with BI and visualization tools such as Tableau, Looker, or Power BI
• Prior experience in a consulting or client-facing environment

Benefits

• Flexible remote working environment.
• Career development opportunities in a fast-growing company.
