Lead Data Scientist

Job Title: Staff AI/ML Engineer & Data Scientist Location: Normal Illinois 61761 - Hybrid Duration: 12+ months Contract with the possibility of extension JOB DESCRIPTION Role Summary We are seeking a Staff AI/ML Engineer & Data Scientist with deep expertise in traditional machine learning, Deep learning and strong MLOps experience to lead the design, deployment, and maintenance of production-grade ML systems. You will architect robust ML pipelines, apply advanced statistical techniques, and ensure models are accurate, explainable, and scalable. While the primary focus will be on traditional supervised, unsupervised, and time-series modeling, light experience with retrieval-augmented generation (RAG) is a plus. The individual needs to have devops experience for setting up Databases, CI/CD (Databricks end-to-end experience is plus) MOST IMPORTANT SKILLS/RESPONSIBILITIES: • Traditional ML Expertise – Apply algorithms such as regression, tree-based models, SVMs, clustering, and forecasting to solve high-impact problems ,feature engineering and hyper parameter tuning (anamoly prediction). The vast majority of data generated today is unlabeled • End-to-End Model Development – Lead the full lifecycle from data preprocessing and feature engineering to training, validation, deployment, and monitoring. • Statistical Analysis – Apply hypothesis testing, Bayesian methods, and model interpretability techniques to ensure reliable insights. • Devops Experience – Experience with database setup, databricks, aws, CI/CD, DevOps/MLOps, VectorDBs, Graph DB. • Master’s degree or PHD is mandatory • This role required to visit site intermittently to Normal,IL site for initial understanding of the scope. • This role required analysis of manufacturing, sensors, PLC data, any prior would be a plus Key Responsibilities • ML Technical Leadership – Define ML architecture, best practices, and performance standards for enterprise-scale solutions. • End-to-End Model Development – Lead the full lifecycle from data preprocessing and feature engineering to training, validation, deployment, and monitoring. • Traditional ML Expertise – Apply algorithms such as regression, tree-based models, SVMs, clustering, and forecasting to solve high-impact problems ,feature engineering and hyper parameter tuning. • Programming & Integration – Build scalable ML pipelines and APIs in Python (primary) and Golang (for backend services). • Mops Implementation – Design and manage CI/CD pipelines for ML, including automated retraining, model versioning, monitoring, and rollback strategies. • Statistical Analysis – Apply hypothesis testing, Bayesian methods, and model interpretability techniques to ensure reliable insights. • Cross-Functional Collaboration – Partner with engineering, analytics, and product teams to align technical solutions with business objectives. • Devops Experience – Experience with database setup, databricks, aws, CI/CD, DevOps/MLOps, vector DBs, GraphDB Qualifications Must Have: • 8+ years of experience in applied ML or data science, including 3+ years in a senior or staff-level role and Devops experience. • Expert proficiency in Python for ML development (Good to have: Golang for backend integration) • Proven experience deploying traditional ML models to production with measurable business impact. • Strong knowledge of ML frameworks (Scikit-learn, Boost, LightGBM) and data libraries (Pandas, NumPy, Stats models). • Hands-on MLOps experience with tools like MLflow (preferred), Databricks(preferred), Kubeflow, Vertex AI Pipelines, or AWS Sage Maker Pipelines. • Experience with model monitoring, drift detection, and automated retraining strategies. • Strong database skills (SQL and NoSQL). • Master’s degree or PHD is mandatory Preferred: • Exposure to retrieval-augmented generation (RAG) pipelines and vector databases. • Time-series analysis and anomaly detection experience. • Cloud deployment expertise (AWS, Azure, GCP). • Familiarity with distributed computing frameworks (Spark, Ray). Soft Skills: • Strategic problem-solver with the ability to align AI solutions to business goals. • Excellent communicator across technical and non-technical stakeholders.
