Job Description

Qualification & Eligibility:

  • Bachelor's or higher degree in a quantitative discipline (computer science, statistics, engineering, applied mathematics)

Working Experience:

  • Minimum 8+ years of experience
  • Startup experience preferred, Edtech work experience bonus

Roles & responsibilities:

Lead the roadmap for Generative AI (GenAI) solutions across product and platform teams.

Architect and optimise RAG pipelines (retrieval, embeddings, hybrid search, re-ranking, caching, latency-cost tradeoffs).

Establish robust evaluation frameworks (automatic + human-in-the-loop) to measure LLM outputs on factuality, reasoning, hallucinations, coverage, and safety.

Lead research and applied innovation around foundation model fi ne-tuning (instruction tuning, LoRA, adapters, PEFT, multi-task fi ne-tuning).

Mentor senior scientists/engineers, setting standards for model development, experimentation, and research rigour.

Partner with Product, Engg, and Business stakeholders to deliver AI systems with measurable business impact.

Skill Sets:

Deep understanding of foundational LLMs (architectures, tokenization, pre-training vs fi ne-tuning, context window optimization).

Strong experience with RAG systems (vector DBs, hybrid retrieval, embeddings, ranking models). Proven ability to design and implement eval pipelines (truthfulness, reasoning quality, safety, alignment).

Hands-on expertise in fi ne-tuning approaches: instruction tuning, LoRA, PEFT, model merging, distillation, prompt-tuning.

Strong background in representation learning, transformers, IR/retrieval models, and embeddings.

Profi ciency in Python, PyTorch/TensorFlow, and production ML pipelines.

Experience with MLOps practices: model serving, monitoring, observability for LLM systems.
