What you'll do

  • Lead the development of analytical, statistical, machine learning, and applied AI solutions for business and client use cases.
  • Translate business questions into structured analytical approaches, modeling strategies, hypotheses, features, evaluation methods, and measurable outputs.
  • Design and execute analyses and models across use cases such as segmentation, forecasting, propensity modeling, anomaly detection, experimentation analysis, recommendation-oriented analysis, and decision support.
  • Work independently with structured, semi-structured, and selected unstructured datasets to derive insights and develop business-relevant solutions.
  • Build, refine, and maintain notebook-based workflows and reproducible analytical assets in Databricks and other cloud-based environments.
  • Apply machine learning and AI methods to support classification, scoring, summarization, pattern detection, feature generation, and business process improvement use cases.
  • Support the evaluation and practical application of LLM-enabled or AI-assisted workflows where they strengthen business analysis, insight generation, or decision support.
  • Participate in model training, tuning, validation, performance review, and comparative evaluation across different analytical and AI approaches.
  • Document assumptions, methodology, feature logic, model decisions, evaluation criteria, limitations, and findings clearly and consistently.
  • Partner with Data Analysts, AI Scientists, AI Engineers, Analytics Engineers, Data Engineers, and Architects to ensure solutions align with business needs, data realities, and technical constraints.
  • Improve delivery quality by identifying opportunities for better reproducibility, stronger evaluation practices, clearer documentation, and more scalable analytical workflows.
  • Follow established governance, privacy, and responsible data and AI use standards in day-to-day work.

What they require

  • Strong working knowledge of statistics, probability, machine learning, and analytical problem solving.
  • Ability to independently manage recurring data science workstreams and deliver reliable outputs with minimal oversight.
  • Strong understanding of supervised and unsupervised learning approaches, feature engineering, model evaluation, error analysis, and analytical problem framing.
  • Ability to work effectively with structured, semi-structured, and selected unstructured datasets.
  • Working knowledge of experimentation design, model validation, and the interpretation of analytical and predictive outputs in business contexts.
  • Growing familiarity with applied AI methods, including LLM-enabled workflows, text-oriented analysis, and AI-assisted feature extraction or classification.
  • Strong familiarity with notebook-based development and collaborative data science workflows, including Databricks.
  • Strong curiosity about patterns, behaviors, drivers, and how advanced analytical methods support decision-making and business value.
  • Strong attention to detail and disciplined approach to validating data, logic, methodology, and outputs.
  • Strong written and verbal communication skills in English, including the ability to explain analytical methods and findings clearly to non-technical stakeholders.
  • Ability to balance technical rigor with practical business and delivery realities.
  • Ability to collaborate effectively across distributed teams in the Americas and work across functions, time zones, and client contexts.

Benefits

  • Flexibility, with remote and hybrid work options (country-dependent)
  • Career advancement, with international mobility and professional development programs
  • Learning and development, with access to cutting-edge tools, training and industry experts
  • Medical, dental, and vision insurance for you and your family, plus employer contributions to Health Savings Accounts
