What you'll work on
- Hands-on development and write algorithms in machine learning, statistical modelling, neural nets, and pattern recognition from data exploration
- Develop, train, and deploy ML models for Time-series forecasting and anomaly detection. Classification and regression on tabular and sensor data, predictive maintenance and failure prediction
- Design end-to-end ML pipelines including Data ingestion, feature engineering, model training, evaluation, and deployment
- Lead and support Root Cause Analysis (RCA) investigations using data-driven approaches
- Build frameworks for Fault Tree Analysis (FTA) and failure mode identification
- Collaborate with domain experts (engineering, operations) to translate failure patterns into ML features and models
Design and develop Agentic AI systems capable of:
- Autonomous reasoning over structured and unstructured data
- Tool usage (query engines, APIs, analytics pipelines)
- Multi-step decision making and diagnostics workflows
Implement LLM-based systems with:
- Tool-calling frameworks
- Retrieval-Augmented Generation (RAG)
- Structured outputs and validation pipelines
Partner with cross-functional teams (Data Engineers, Software Engineers, Domain Experts)
Build scalable, production-ready solutions using:
- Python-based ML frameworks (e.g., TensorFlow, PyTorch, Scikit-learn)
- Data processing tools (Pandas, Spark, SQL)
Deploy models and services using:
- REST APIs (FastAPI, Flask)
- Containerization (Docker, Kubernetes)
Work with modern data platforms:
- Time-series DBs (e.g., Prometheus, InfluxDB)
- Analytical DBs (e.g., ClickHouse, PostgreSQL)
- Vector DBs (e.g., Qdrant, FAISS)
