Machine Learning Engineer II ( Data & Audience Platform Team), Hyderabad

About the role

As a Machine Learning Engineer II, you will work alongside Senior and Staff engineers to build and maintain production ML pipelines, contribute to model development, and grow into a well-rounded ML engineer who bridges data science and software engineering. This is a hands-on role for someone with roughly 2-4 years of experience who is eager to work on high-impact ML systems at scale - from probabilistic identity graphs to single-title affinity models - and who wants to develop deep expertise across the full ML lifecycle.

Responsibilities

• ML Development & Modeling
• Build and maintain end-to-end ML pipelines for training, evaluation, and batch inference across use cases such as identity resolution, audience segmentation, and content affinity modeling.
• Implement and experiment with supervised, unsupervised, and ranking models in Python (scikit-learn, XGBoost/LightGBM, PyTorch).
• Engineer features from first-party viewership, engagement, subscription, and behavioral signals, guarding against data leakage, collinearity, and training/serving skew.
• Run structured offline experiments; evaluate with the right metrics (precision/recall, F1, AUC-ROC, calibration, lift) and document findings in MLflow.
• ML Infrastructure & Engineering
• Develop and maintain data and feature pipelines on Databricks (PySpark, Delta, Workflows) that feed the feature store and model-training workflows, with attention to idempotency and reproducibility.
• Write clean, tested, production-quality Python following engineering best practices (unit tests, code reviews, CI/CD).
• Use MLflow for experiment tracking, model registration, and versioning under the guidance of senior engineers.
• Support deployment and monitoring of batch inference jobs integrated with downstream activation platforms (e.g., Mosaic, FreeWheel, GAM) and data in Snowflake.
• Agentic AI & Modern Tooling
• Use AI-assisted development tools (Cursor, GitHub Copilot, Amazon Q) to accelerate coding, debugging, and documentation under guidance.
• Leverage Databricks Genie for natural-language exploration of governed Unity Catalog datasets - querying ML feature tables, model outputs, and audience segments.
