Staff Data Scientist, AI Products

Consumer Edge (“CE”) delivers real-time transaction-based intelligence enriched by AI and deep industry expertise. Our mission is to turn complex consumer and business data into actionable insights. Our technology team is distributed across Europe and the US and is driven by curiosity and rigor.

As a Staff Data Scientist on the AI Products team, you’ll design, evaluate & deliver AI systems including chatbots, RAG frameworks, and multi-agent workflows. You will lead end to end delivery of highly visible projects within the team, partnering closely with engineers and product stakeholders to take ideas from exploration through production.

• →Develop and evaluate AI and LLM applications for retrieval, generation, and conversation.
• →Build evaluation pipelines and establish robust measurement standards.
• →Collaborate with Software Engineers to productionize models.
• →Research prompt strategies, fine-tuning approaches, and RAG architectures.
• →Define metrics and experiments that connect model performance to user impact.
• →Document and communicate findings to technical and business stakeholders.
• →Mentor junior scientists and champion data quality standards.
  
  

• Strong background in Applied Data Science or Machine Learning with 7 yrs + experience.
• Hands-on experience building and evaluating LLM-powered systems, including RAG, conversational AI, and agentic / multi-agent workflows.
• Deep understanding of LLM evaluation techniques (offline benchmarks, human-in-the-loop review, LLM-as-judge, and online experimentation).
• Background in statistics, experimentation, and ML research methods
• Hands-on experience writing high quality production code (Python, SQL) and experience with various data science libraries (Pandas, scikit-learn, PyTorch, TensorFlow).
• Experience with ML platforms and orchestration tools (e.g., Vertex AI, MLflow, Dagster), or equivalent systems
