This is a Hybrid role (2 days/week in office)

We are seeking a highly analytical and technically proficient Senior ML/AI Engineer to join our ARC team. This role is ideal for someone with a strong foundation in mathematics, statistics, and programming, and a passion for applying AI to solve complex financial problems. You will work to develop AI/ML/DS features for enterprise-wide AI products to develop models, optimize strategies, and contribute to the evolution of our AI-powered financial systems.

• 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
• Lead development of 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
• Develops prediction systems and machine learning algorithms.
• Research and evaluate additional technologies and tools for developing innovative data solutions for business stakeholders i.e. What if analysis (forecasting, next-best-step), Domain Adaptation and Transfer forecasting, Temporal Convolutional Networks, long-term short-term, pricing models, Autoregressive Models.
