Senior Data Scientist – GenAI & Traditional AI

About NStarX

NStarX is an AI-first enterprise transformation company delivering “Service-as-Software” solutions through our unified DLNP (Data Lake and Neural Platform). We help enterprises become AI-native through federated learning, generative AI, data engineering, and platform services, with a strong focus on data sovereignty and privacy-preserving AI solutions. Our clients span healthcare, financial services, media, and other regulated industries.

Role Summary

We are seeking a Senior Data Scientist with strong hands-on experience across Traditional AI/ML and Generative AI (GenAI). This role will primarily focus on one project at a time, owning core experimentation and implementation workstreams, while also guiding and grooming junior data scientists to ensure consistent, high-quality delivery. You’ll work closely with the Lead Data Scientist, AI Engineers, Data Engineers, and MLOps to build scalable, production-ready AI capabilities and support client-facing discussions and demos as needed.

Key Responsibilities

Model Development & Experimentation (Traditional AI + GenAI)

• Execute end-to-end AI/ML experimentation for a single project: problem framing, dataset readiness, feature engineering, model training/tuning, evaluation, and iteration.
• Build and optimize GenAI pipelines using proprietary and open-source models depending on project needs.
• Contribute to LLM-driven feature development with working knowledge of model behavior, embeddings, prompting strategies, context management, and evaluation.

RAG & Agentic Implementation

• Implement and improve RAG pipelines (document ingestion, chunking strategies, embeddings, retrieval, reranking, grounding, and evaluation).
• Develop agentic workflows using modern agent frameworks and tool integrations (multi-step execution, tool use, safety/guardrails).
• Assist in defining evaluation methods for GenAI (faithfulness, relevance, hallucination risk, latency, cost).

Engineering Collaboration & Production Readiness

• Work with engineering and MLOps teams to transition experiments into production-grade pipelines.
• Contribute to performance tuning, observability, and reliability of AI services (metrics, logging, monitoring, error analysis).
• Ensure implementation follows best practices for maintainability, scalability, and cost efficiency.

Mentorship & Team Enablement

• Guide and groom junior data scientists through structured mentorship: task planning, implementation reviews, and feedback.
• Help define reusable assets (notebooks, evaluation templates, baselines, documentation) to improve team velocity and quality.
• Support the Lead Data Scientist in breaking down tasks and estimating effort for your workstream.

Stakeholder Support

• Participate in technical discussions with internal stakeholders and clients; support demos and walkthroughs where applicable.
• Clearly communicate experimental results, trade-offs, and recommendations through structured documentation and presentations.

Required Qualifications

• 5+ years of hands-on experience in data science / machine learning with delivered outcomes.
• Practical experience in both Traditional ML (supervised/unsupervised methods, NLP, time series, recommendations, etc.) and GenAI (LLM-based features).
• Hands-on experience building or contributing to RAG systems; familiarity with agentic frameworks is strongly preferred.
• Solid understanding of model evaluation, experimentation rigor, and iterative improvement cycles.
• Ability to independently own tasks within a project and deliver with minimal supervision.
• Experience mentoring or guiding junior team members through reviews and coaching.
• Strong communication and documentation skills.

Preferred Qualifications

• Graduates from Tier 1 / Tier 2 colleges preferred (e.g., IITs, NITs, IIITs, BITS, top state universities and reputed private institutions).
• Experience with enterprise-grade requirements: data privacy, security, governance,
  and compliance.
• Familiarity with open-source and proprietary model ecosystems and selection trade-
  offs.
• Exposure to MLOps/LLMOps practices (CI/CD, model/prompt versioning,
  monitoring, A/B testing).

Key Competencies

• Strong hands-on execution and ownership (single-project focus)
• Structured problem-solving and experimentation discipline
• Mentorship mindset (grooming junior DS)
• Cross-functional collaboration with engineering and MLOps
• Clear communication of results, risks, and recommendations

Reporting & Collaboration

• Reports to: Lead Data Scientist / AI Product Engineering Lead
• Collaborates with: AI Engineers, Data Engineers, MLOps/DevOps, Product/Program stakeholders, and (as needed) clients
