• Design and develop Machine Learning models (Supervised, Unsupervised, and Reinforcement Learning), AI (Generative models and Agent Orchestration) models, and Deep Learning models (e.g., Neural Networks and autoencoders).
• Run Machine Learning tests and experiments.
• Train and retrain systems to prevent drift and optimize results.
• Solve complex problems with multi-layered data sets, extend existing ML frameworks (Scikit-Learn, XGBoost, Tensorflow) and AI frameworks (Keras, Lang Chain).
• Leverage and develop advanced analytics models (network based, forecasting, rules-based), implement said algorithms, and build tools to apply them.
• Turn structured, semi-structured and unstructured data into useful information
• Develop ML/AI algorithms to analyze huge volumes of historical data to derive insights, make decisions, and form predictions.
• Run tests, perform statistical analysis, and interpret test results
• Establish the main functions of the digital foundations: (Hypergraph) Scenario Engine and Network based Methods: graph-based modeling tool that maps relationships between entities and simulates cascading scenarios
• Exposure to Quant Machine Learning tailored to quantitative finance, driving more accurate forecasting, risk modeling, pricing, and portfolio optimization;
Chatbots (i.e., Distribution)
• Use analysis to provide recommendations and advice for business leaders to maintain to maintain market competitiveness.
• Provide guidance (scoring, decisioning) in areas such as Multi-Objective optimization, safe RL and decision support, network propagation algorithms, entity resolution, clustering.
What you need to succeed:
• Master’s or Ph.D. in Mathematics, Statistics, Computer Science, Data Science, Physics, AI, Machine Learning or a related field.
• Leadership experience driving initiatives related to AI/GenAI/ML assets
• Experience in model development (ML/ Data Science, AI/GenAI) within financial services or technology sectors
• Proficiency in Python and SQL, Tensor Flow, PyTorch, XGBoost, Scikit-learn
• Strong grasp of Artificial Intelligence and Machine Learning frameworks and stacks.
• Familiarity with cloud platforms (AWS, Azure, GCP) and CI/CD pipelines is advantageous
• Intellectual curiosity and adaptability to emerging AI and quant finance trends.
• Strong communication skills to explain complex models to non-technical stakeholders.
• Ability to work independently and collaboratively in a fast-paced, multidisciplinary environment.
• Attention to detail and a rigorous approach to model validation and testing
