We are proud of:
The role
We are looking for an experienced Senior Data Scientist to drive advanced analytics, causal reasoning, and AI-powered decision intelligence across multiple use cases within our AI portfolio. This role goes beyond traditional modeling and focuses on building production-grade systems that combine predictive, causal, and generative AI capabilities to directly influence business outcomes.
You will work at the intersection of data science, machine learning, and GenAI, turning complex data into actionable insights, automated decisions, and intelligent workflows across domains such as marketing, operations, forecasting, and optimization.
This is not a purely retrospective analytics role. You will design and deploy systems that integrate experimentation, observational data, machine learning, and generative AI into real-time or near-real-time decision-making pipelines.
You will collaborate closely with data engineers, ML engineers, analysts, and platform teams, contributing to shared modeling standards and cross-functional AI architecture.
Role responsibilities
Advanced Analytics & Machine Learning
- Develop and deploy machine learning models across use cases (forecasting, optimization, recommendation systems)
- Apply statistical, predictive, and prescriptive modeling techniques to solve business problems
- Build reusable modeling frameworks that can scale across multiple domains
Causal Inference & Decision Intelligence
- Design and implement causal inference methods (e.g., uplift modeling, experiments, quasi-experimental methods)
- Translate observational and experimental data into actionable business insights
- Embed causal reasoning into decision systems that guide actions (e.g., optimization, prioritization, trade-offs)
Generative AI & Intelligent Systems
- Integrate GenAI capabilities (e.g., LLMs, RAG pipelines, agent-based systems) into data science workflows
- Contribute to the development of intelligent agents and AI-assisted decision-making systems
- Combine structured data models with unstructured data and GenAI outputs
Forecasting & Optimization
- Build forecasting models (time-series, probabilistic, causal) to support planning and operations
- Develop optimization approaches for resource allocation, scheduling, or campaign performance
- Ensure models are explainable and actionable in business contexts
Production & Platform Integration
- Build and maintain production-grade data science solutions
- Collaborate with engineering teams to integrate models into scalable APIs and platforms
- Ensure robustness, monitoring, and lifecycle management of deployed models
Cross-Functional Collaboration
- Partner with data engineering, analytics, and product teams to ensure data readiness and solution adoption
- Review and validate modeling approaches across teams (forecasting, experimentation, ML)
- Contribute to best practices in AI, ML, and data science within the organization
Must have qualifications
Data Science & Statistical Expertise
- Strong experience in machine learning, statistics, and applied data science
- Experience with causal inference, experimentation, or decision science methodologies
- Solid understanding of forecasting, optimization, or analytical modeling techniques
Technical Skills
- Strong programming skills in Python and SQL
- Experience building and deploying production-ready data science or ML systems
- Familiarity with model lifecycle management (training, deployment, monitoring)
Cloud & Platform Experience (Key Requirement)
- Hands-on experience with at least one major cloud platform:
- Azure (preferred), AWS, or GCP
- Experience working with modern data and AI platforms (e.g., Azure ML / Azure AI, Databricks, or similar ecosystems)
Domain & Data Experience
- Experience working with complex, multi-source datasets (e.g., transactional, behavioral, operational data)
- Ability to translate business problems into analytical frameworks
Mindset
- Strong problem-solving skills with focus on business impact
- Ability to translate complex models into actionable decisions
- Strong collaboration and communication skills across technical and business teams
Nice to have qualifications
- Deep experience in marketing analytics, attribution, or campaign measurement
- Hands-on experience with:
- Uplift modeling, geo experiments, synthetic control
- Marketing Mix Modeling (MMM)
- Experience with GenAI frameworks (e.g., LangChain, LangGraph, RAG architectures, agent frameworks)
- Familiarity with data engineering tools (e.g., Spark, Airflow, dbt)
- Experience with platforms such as Snowflake, Fabric, or BigQuery
- Exposure to advanced time-series methods and probabilistic forecasting
- Experience working in Agile, product-led, or consulting environments
