To be considered for this role, you will need:

  • Master’s Degree in Statistics, Data Science, Computer Science, or a related field
  • 4+ years of experience in SQL/Spark, R, Python
  • 4+ years of Experience building and applying machine learning or NLP models to business problems
  • Strong understanding and practical experience with machine learning techniques such as regression, tree-based models, ensemble methods, and neural networks, with experience applying these methods to large, real-world datasets and production systems
  • Experience working with production machine learning systems, including model monitoring, performance tracking, and model improvements
  • Experience with NLP techniques such as Named Entity Recognition (NER), text classification, sentiment analysis, tokenization, or information extraction
  • Experience working with large datasets and distributed data processing frameworks (e.g., Spark)
  • Experience with cloud platforms (AWS, GCP, or Azure)
  • Ability to work independently, prioritize tasks across multiple projects, and contribute new ideas and initiatives.
  • Passion for continuous learning and improving data science processes.
What’s in it for you: 
  • Competitive compensation, benefits and generous time-off policies
  • 4-Day summer work weeks and a winter holiday break
  • 401(k) / DCPP matching
  • Annual bonus program
