Data Scientist III

Are you ready to grow your data science expertise and work on impactful AI and machine learning projects? Would you enjoy building advanced analytics, machine learning, and GenAI solutions that drive real business value?

About our team: We are a fast-moving, high-impact Data Science & AI team building real-world GenAI and ML solutions across the LexisNexis business. Our work powers smarter decisions for Product, Sales, Finance, Marketing, Customer Success, and Engineering—everything from predictive models to enterprise GenAI applications to automation that transforms how teams operate. We are data science generalists who enjoy variety. One day, it may be designing a new GenAI workflow, the next it may be deploying a model into Salesforce or developing a pipeline in Databricks. We work closely with stakeholders to build practical solutions that are used and deliver measurable impact. If you want to experiment, build, ship, and see your work make a difference across a global organisation, you will feel right at home with us.

About the role: We are seeking a Data Scientist III who is a strong Data Science Generalist.

In this role, you will help design, build, and deploy AI and ML solutions that support key business functions across Product, Sales, Finance, Marketing, Customer Success, and Engineering. You will contribute across the full solution lifecycle, including problem framing, data preparation, modelling, experimentation, prompt engineering, deployment, monitoring, and stakeholder communication. This position is ideal for a versatile data scientist who enjoys solving diverse problems, working across multiple systems, and contributing to measurable business impact.

Responsibilities:

• Build GenAI applications using OpenAI APIs, embeddings, vector search, and RAG.
• Apply prompt engineering and help define evaluation approaches for GenAI outputs.
• Develop and deploy ML models (e.g., churn, propensity-to-buy, sentiment/feedback, lead scoring, customer intelligence).
• Own the full ML lifecycle: data prep, experimentation, deployment, and monitoring.
• Build and optimise feature pipelines and model scoring jobs with Python, Databricks, Spark, and Delta Lake.
• Use AWS (S3, Redshift, Lambda) for data automation and orchestration.
• Improve pipeline data quality, observability, lineage, and documentation.
• Integrate models/data with enterprise platforms (Salesforce, Oracle Fusion/Service Cloud/Peoplesoft).
• Deliver real-time and batch workflows to improve CRM, sales, service, and marketing operations.
• Partner cross-functionally to define KPIs, generate actionable insights, communicate clearly, and drive adoption via demos/docs/training.

Requirements:

• Strong Python programming skills.
• Experience with OpenAI APIs, LLM workflows, and prompt engineering.
• Solid machine learning fundamentals, including supervised learning, NLP, and feature engineering.
• Experience with Databricks, Spark, and Delta Lake.
• Strong SQL skills with experience working on large datasets.
• Experience with AWS, including S3 and Lambda.
• Familiarity with Redshift, Snowflake, or other cloud data warehouses.
• Experience working with behavioural or business datasets.
• Ability to work across machine learning, analytics, data engineering, and integrations.
