Job Description
We are seeking an exceptionally skilled Enterprise Data Scientist to lead cutting-edge analytics, AI, and machine learning initiatives across the organization. This role requires mastery of mathematics, statistics, machine learning, deep learning, reinforcement learning, and optimization, combined with enterprise-scale data engineering, cloud platforms, and MLOps expertise. You will design, deploy, and monitor high-impact AI/ML systems that drive enterprise strategy, operational efficiency, and business innovation.

Roles & Responsibilities

    1.

    Advanced Analytics & Modeling

    • Design, implement, and deploy predictive, prescriptive, and optimization models at enterprise scale.
    • Apply mathematical modeling including linear algebra, multivariate calculus, stochastic processes, graph theory, and optimization techniques (convex, non-convex, combinatorial).
    • Develop statistical models: Bayesian inference, hierarchical modeling, time series, survival analysis, causal inference, and probabilistic graphical models.
    • Lead feature engineering, dimensionality reduction, embeddings, and representation learning for complex datasets.
    2.

    Machine Learning & AI

    • Implement supervised, unsupervised, semi-supervised, and reinforcement learning algorithms.
    • Build deep learning architectures: CNNs, RNNs, LSTMs, Transformers, Graph Neural Networks (GNNs), and Autoencoders.
    • Develop NLP solutions: embeddings, word2vec, BERT, GPT-style models, sequence modeling, summarization, and sentiment analysis.
    • Apply graph analytics for network data, knowledge graphs, and recommendation systems.
    • Evaluate models rigorously using cross-validation, AUC, precision/recall, F1, SHAP/LIME, and advanced statistical tests.
    3.

    Enterprise-Scale Data Engineering

    • Architect and maintain large-scale data pipelines using Spark, Hadoop, Kafka, Flink, or equivalent.
    • Integrate heterogeneous structured, semi-structured, and unstructured data from multiple enterprise systems.
    • Ensure data quality, governance, security, and compliance (GDPR, HIPAA, SOC2).
    4.

    MLOps & Production Deployment

    • Implement MLOps best practices: model versioning, automated testing, CI/CD pipelines, containerization, and orchestration.
    • Deploy models on cloud platforms (AWS SageMaker/EMR, GCP Vertex AI, Azure ML) and monitor performance and drift.
    • Build real-time and batch inference pipelines for high-throughput enterprise applications.
    5.

    Strategy, Leadership & Collaboration

    • Translate complex analytical outputs into actionable business insights for executives.
    • Collaborate with engineering, product, finance, operations, and marketing teams to embed AI/ML solutions.
