Senior AI Engineer/Data Scientist

Job Description This is a remote position. Scope: We are hiring a pioneering, fully autonomous Senior AI Engineer/Data Scientist to own the complete data science lifecycle for our flagship prediction model project. This role is mission-critical — the candidate will be the single point of expertise responsible for sourcing, analyzing, and engineering all data that powers our predictive models. Operating independently with minimal supervision, this individual must combine deep AI/ML mastery, hands-on engineering skills, and sharp business acumen to deliver measurable, production-grade outcomes. Key Responsibilities: Data Analysis & Pipeline Ownership ▸ Lead end-to-end analysis of large, complex, multi-source datasets to surface patterns driving model inputs ▸ Identify, collect, clean, validate, and transform all data required for prediction model consumption ▸ Design and maintain scalable, production-grade data pipelines (training, validation, inference) ▸ Perform deep EDA, data profiling, and quality audits to ensure model-ready data standards Predictive Modeling & AI/ML ▸ Architect, train, evaluate, and iterate ML models — supervised, unsupervised, and reinforcement learning ▸ Own feature engineering: selection, extraction, transformation, and dimensionality reduction ▸ Apply advanced techniques: deep learning, NLP, time-series forecasting, ensemble methods ▸ Benchmark, A/B test, and monitor models in production; drive continuous performance improvement ▸ Deploy models via REST APIs (FastAPI/Flask); ensure reproducibility and scalability Independent Ownership & Leadership ▸ Self-direct from problem definition through solution delivery with zero hand-holding ▸ Translate ambiguous business problems into precise, executable data science problem statements ▸ Communicate model results and data insights clearly to technical and non-technical stakeholders ▸ Document all experiments, methodologies, and outcomes — audit-ready and reproducible ▸ Champion best practices across the data science lifecycle; mentor junior team members QUALIFICATIONS ▸ B.S./M.S./Ph.D. in Computer Science, Statistics, Mathematics, or equivalent quantitative field (Master's/Ph.D. strongly preferred) ▸ 5+ years of hands-on data science experience with at least 2 years delivering production-grade ML models ▸ Proven ability to own and deliver end-to-end data science projects independently ▸ Portfolio demonstrating innovation in predictive modeling and measurable business impact ▸ Kaggle rankings, research publications, or open-source ML contributions are a strong plus ▸ Experience in a fast-paced, data-driven, decision-model environment REQUIRED SKILLS & QUALIFICATIONS Core Data Science & Mathematics ▸ Statistics (Bayesian inference, hypothesis testing, regression, distributions) ▸ Linear algebra, calculus, and probability applied to ML model design ▸ Supervised & unsupervised learning, anomaly detection, clustering ▸ Time-series analysis & forecasting: ARIMA, Prophet, LSTM Programming & Development ▸ Python (Expert): NumPy, Pandas, Scikit-learn, Statsmodels, Matplotlib, Plotly ▸ SQL (Advanced): window functions, CTEs, query optimization ▸ Git / GitHub; CI/CD for ML; MLOps with MLflow or Kubeflow ▸ Docker & Kubernetes for model containerization and serving AI / ML Frameworks (Must-Have) ▸ TensorFlow and/or PyTorch — deep learning architectures ▸ XGBoost, LightGBM, CatBoost — gradient boosting & ensemble methods ▸ Hugging Face Transformers — NLP, LLMs, and fine-tuning ▸ SHAP, LIME — model explainability and interpretability ▸ LLMs / Generative AI / Prompt Engineering — strong advantage Cloud & Data Infrastructure ▸ AWS (SageMaker, S3, Glue), GCP (Vertex AI, BigQuery), or Azure ML ▸ Apache Spark / PySpark — distributed data processing ▸ Airflow / Prefect — pipeline orchestration Snowflake (Good to Have) ▸ Snowflake Data Cloud: querying, Snowpark for Python ML pipelines ▸ Snowflake Cortex AI / ML Functions for in-database ML ▸ dbt for data transformation; data governance within Snowflake
