Full Job Description
Skills and Competencies
  • Hands-on experience building, training, and evaluating deep-learning models - not just familiarity with the concepts. You should be comfortable working with modern architectures (e.g., transformers, sequence, and representation-learning models) and reasoning about where they outperform classical approaches and where they don't.

  • Strong programming skills in Python or R.
  • Depth in one or more deep-learning domains relevant to our work: representation learning for structured financial data, NLP for filings/news/unstructured text, or forecasting for macro and financial time series. (Preferred)
  • Exposure to cloud platforms such as AWS, GCP, or Azure. (Preferred)
  • Experience developing and deploying models on large, complex, real-world datasets: financial statements, macro time series, text, and other unstructured sources. (Preferred)
  • Ability to own the full model-development lifecycle: conceptualization, data exploration, design, estimation, validation, deployment, user training, and monitoring. (Preferred)
  • Research output: publications, conference work, or open-source contributions. (Preferred)

Education
  • Ph.D. in Computer Science, Statistics, Applied Mathematics, Economics, Finance, Operations Research, or a related quantitative field; or master's degree in any of these fields, with 2-3 years of experience in the financial industry.

Responsibilities

Partner across Moody's business lines to enhance modeling and analytical frameworks, incorporating state-of-the-art ML and deep-learning techniques.
  • Design and deliver innovative analytical solutions, leveraging deep learning and quantitative methods to address complex financial, economic, and operational problems.
  • Identify opportunities for automation and model-based decision enhancement, applying neural networks, representation learning, and statistical methods to improve accuracy, efficiency, and performance.
  • Collaborate with cross-disciplinary teams to build scalable, cloud-based analytical platforms grounded in clean, well-engineered data.
  • Apply deep expertise in statistical, machine learning, and deep-learning methods to develop insights and decision frameworks for internal stakeholders and clients.
  • Provide technical leadership, advising business partners on modeling strategy, tradeoffs, and the appropriate role of deep learning in analytical solutions.
  • Communicate technical subject matter clearly and concisely, ensuring that insights, limitations, and implications are well understood by diverse audiences.
