Data Scientist - Machine Learning

In this role, you will lead the transition from a manual, prototype-based cleaning process to a fully automated, scalable Machine Learning pipeline. You will be responsible for identifying outliers within large-scale datasets, ensuring the accuracy of consensus pricing for financial derivatives, and building a system that learns and improves through a continuous human-in-the-loop feedback mechanism., * Model Design & Development: Design, build, train, and validate sophisticated ML models (including Random Forests and Boosted models) to automatically flag “bad” valuations across multiple dimensions.

• Pipeline Automation (AWS): Build robust, production-ready data pipelines within the AWS ecosystem (S3, Lambda, etc.) to process high daily volumes of valuation data within tight windows.
• Explain ability & Confidence: Develop methods to measure model confidence and provide clear reasoning for valuation decisions. You will ensure the system flags borderline cases for expert review to maintain high integrity.
• Continuous Learning: Implement feedback loops where human corrections are automatically integrated into training data, allowing the model to evolve and improve accuracy over time.
• Collaborative Innovation: Generate and test hypotheses to drive incremental progress, working closely with both technical teams and business stakeholders.

• Commercial Experience: 2-5 years in a quantitative or data science role. Focus on Machine learning during this period
• Technical Proficiency: Strong mastery of Python and demonstrable experience deploying/monitoring models in an AWS production environment.
• ML Expertise: Deep statistical understanding of machine learning techniques, specifically classification and optimisation techniques to manage trade-offs between related data points.
• Analytical Mindset: Proven ability to surface features that drive decisions even when they are not directly observable from raw training data.
• Communication: Ability to collaborate across technical and business functions, with the potential to grow into a client-facing capacity., * Education: Masters or Ph.D. in a highly quantitative field (Statistics, Financial Engineering, Computer Science, or Mathematics).
• Industry Background: Any industry is considered but financial services would be a plus
