• Build data pipelines and unified data structures from multiple APIs and databases

• Collaborate with engineering and product teams to identify new AI opportunities

• Continuously improve model performance, accuracy and scalability

Skills & Experience

• 2+ years of experience as a Data Scientist or Machine Learning Engineer

• Strong Python programming skills

• Experience with ML libraries such as scikit-learn

• Experience with deep learning frameworks such as PyTorch or TensorFlow

• Experience working with AWS / SageMaker or similar cloud ML platforms

• Strong data manipulation skills using NumPy, Pandas or SciPy

• Experience working with SQL and complex datasets

• Familiarity with Linux / Unix environments

Desirable Experience

• Experience working with LLMs and generative AI

• Knowledge of LangChain or similar orchestration tools

• Experience working with vector databases for RAG workflows

What’s on Offer
