Senior Data Scientist

Apply data analysis, AI, and modelling techniques to understand user behaviour, identify opportunities, and inform product improvements. Write robust, reusable, and extensible code to support analysis, modelling, and operationalization at scale. Use AI-powered tools in your daily work to accelerate analysis, experimentation, and solution development. Develop and maintain metrics and evaluation frameworks to assess the quality, performance, and impact of services. Drive data-driven decision making by presenting clear, actionable insights to senior leaders and stakeholders. Collaborate in a cross-functional environment with local and remote partners to deliver scalable, elegant, and impactful solutions. Acquire, prepare, and validate datasets for analysis and modelling, while contributing to best practices in data collection and data quality. Evaluate and improve existing products to ensure intelligent services evolve to meet user needs. Design, evaluate, and optimize prompts and fine-tuning strategies for large language models.
