Role Overview

We are seeking a Senior Machine Learning Engineer (Lead) with 5-6 years of experience to architect, develop, and lead advanced time-series forecasting solutions for high-impact financial use cases. This role requires deep technical expertise in machine learning, strong financial domain knowledge, and the ability to translate research-driven models into production-grade systems within mission-critical environments.

You will play a pivotal role in building robust, interpretable, and scalable forecasting models supporting financial risk management, FX exposure, treasury planning, and multi-entity forecasting.

Key Responsibilities

1. Technical Leadership & Model Development

• Lead end-to-end development of time-series forecasting solutions - from data acquisition and feature engineering to deployment and monitoring.
• Architect scalable ML pipelines tailored for financial forecasting use cases.
• Develop and benchmark classical statistical models (ARIMA, SARIMA, ETS) alongside ML approaches (XGBoost, Gradient Boosting, Prophet, etc.).
• Design advanced time-series features including lag structures, rolling statistics, seasonal/trend decomposition, Fourier terms, regime indicators, and exogenous variable integration.
• Implement time-aware cross-validation strategies and Bayesian hyperparameter optimization.
• Conduct rigorous backtesting aligned with financial validation methodologies.

2. Financial Modeling & Risk Analytics

• Build forecasting models for:
• FX exposure forecasting
• Treasury cash flow prediction
• Intercompany netting optimization
• Financial risk modeling
• Multi-currency and multi-entity forecasting
• Quantify model uncertainty and incorporate confidence intervals for financial decision-making.
• Perform anomaly detection and outlier analysis in financial time-series datasets.
• Ensure models align with financial reporting cycles, treasury constraints, and accounting standards.

3. Production Deployment & MLOps

• Design reproducible ML workflows and production-ready pipelines.
• Implement model versioning, monitoring, drift detection, and automated retraining strategies.
• Collaborate with engineering teams to deploy solutions in cloud environments.
• Build business-facing dashboards (Streamlit, Tableau, Power BI).
• Ensure model governance, documentation, and auditability standards are maintained.

4. Collaboration & Mentorship

• Translate complex technical insights into actionable business narratives.
• Partner with Finance, Treasury, Risk, and Executive stakeholders.
• Mentor junior ML engineers and establish best practices in feature engineering, validation, and interpretability.
• Promote technical excellence and maintain high code quality standards.

Requirements

• 5-6 years of hands-on ML engineering experience with strong expertise in time-series forecasting.
• Proven experience in financial domain use cases (FX forecasting, treasury operations, financial risk modeling, etc.).
• Deep understanding of time-series feature engineering (lags, rolling aggregates, decomposition, exogenous drivers).
• Experience with classical statistical forecasting models (ARIMA, SARIMA, Exponential Smoothing).
• Strong Python proficiency (pandas, NumPy, scikit-learn, XGBoost).
• Experience with Prophet or comparable forecasting frameworks.
• Expertise in:
• Time-aware cross-validation
• Bayesian hyperparameter optimization
• Model interpretability techniques (SHAP, LIME)
• Strong understanding of evaluation metrics (MAPE, MAE, RMSE) and statistical validation methods.
• Experience building data pipelines and working in research environments (e.g., Jupyter).
• Strong communication skills for both technical and finance stakeholders.
• Bachelor’s or Master’s degree in Computer Science, Data Science, Statistics, or a related field.

Preferred / Advanced Skills

• Experience in multi-entity and multi-currency financial forecasting environments.
• Familiarity with cloud ML platforms (AWS SageMaker, Azure ML, GCP AI).
• Experience implementing CI/CD and MLOps frameworks.
• Exposure to probabilistic forecasting and Bayesian modeling approaches.
• Knowledge of financial regulations, treasury workflows, and corporate finance processes.

Why Join Us

• Work on high-impact financial forecasting problems that directly influence strategic decision-making.
• Lead cutting-edge machine learning initiatives in a mission-critical environment.
• Collaborate with cross-functional leadership across finance, risk, and engineering.
• Opportunity to architect scalable ML systems from research to enterprise production.
• Be part of a culture that values innovation, ownership, and technical excellence.
