Primary Objective

We are seeking a Senior Data Scientist / ML Engineer specializing in Generative AI to design, evaluate, optimize, and productionize AI/ML solutions for enterprise applications—including RAG systems, AI agents, intelligent automation, and model evaluation platforms.

The role focuses on improving AI accuracy and retrieval quality, reducing hallucinations, benchmarking LLMs, and building reliable solutions for enterprise-scale deployments.

Success looks like:measurable gains in retrieval/answer quality, robust evaluation frameworks in production, and explicit collaboration with AI engineering to ship governed, reliable GenAI systems.

Key Responsibilities

Primary
- Design and develop machine learning and Generative AI solutions.
- Build and optimize RAG pipelines, retrieval strategies, embeddings, and semantic search.
- Evaluate and benchmark LLMs for accuracy, performance, and reliability.
- Develop AI evaluation frameworks for hallucination detection, accuracy measurement, bias/toxicity detection, and ground-truth validation.
- Optimize prompts, models,



and retrieval workflows.
- Collaborate with AI engineering teams to deploy models into production.

Also expected
- Create training, validation, and testing datasets.
- Perform model benchmarking, A/B testing, and performance analysis.
- Fine-tune foundation models when required.
- Implement model monitoring, observability, and ongoing evaluation processes.

Must-Have Experience & Skills
- 5–10 years of experience in data science, machine learning, or related applied ML roles.
- Strong Python programming skills, with Pandas, NumPy, and Scikit-learn.
- Strong foundation in supervised/unsupervised learning, statistical modeling, feature engineering, and model evaluation techniques.
- Hands-on Generative AI experience with LLM evaluation, prompt engineering, RAG architectures, embedding models, fine-tuning approaches, and agent evaluation frameworks.
- Experience with PyTorch and/or TensorFlow.
