Senior Machine Learning Engineer (Search, Recommendations & Conversational AI)

Location: Remote

Role Type: Senior IC (P3+)

Team: Discovery – Search, Recommendations & AI Experiences

Urgency: Immediate (pre–IPL launch milestones)



About the Role

We are building next-generation conversational search, personalized recommendations, and AI-driven discovery for one of India’s largest entertainment ecosystems. This role is for a hands-on ML Engineer who can design, train, and productionize models powering search relevance, retrieval, personalization, and LLM-based conversational experiences at massive scale.

You will work closely with backend, platform, and catalog enrichment teams to deliver high-quality ML components under tight performance and latency constraints.



Key Responsibilities

  • Build and improve search ranking, retrieval, and query understanding models.
  • Develop ML components for Conversational Search:
  • Multi-turn context handling
  • Query intent detection and classification
  • Retrieval-augmented generation (RAG) pipelines
  • Reasoning workflows (ReAct, static + dynamic agent flows)
  • Design and optimize embedding models, vector stores, and similarity search systems.
  • Build personalized ranking and recommendation models using deep learning.
  • Work on large-scale ML systems optimized for:
  • Low latency
  • High throughput
  • Cost-efficient inference
  • Implement ML pipeline best practices (versioning, monitoring, A/B testing, observability).
  • Collaborate with platform teams to integrate ML services across search, recommendations, and conversational agents.
  • Develop caching strategies (prompt cache, vector cache, similarity caching) to hit strict SLA targets.
  • Contribute to long-term roadmap: foundational retrieval models, multi-objective optimization, user lifecycle modeling.



Required Qualifications

  • 4–10 years of experience in Machine Learning / Applied ML engineering.
  • Strong foundations in ML, deep learning, Transformers, and neural retrieval.
  • Hands-on experience with:
  • Search systems (retrieval + ranking)
  • Recommendation models
  • Embedding models & vector databases
  • TensorFlow / PyTorch
  • Proven experience building production-grade ML systems at scale.
  • Familiarity with LLMs, RAG architectures, prompt engineering, and agent workflows.
  • Strong coding skills (Python) and experience with modern ML stack (TensorFlow, PyTorch, Faiss/ScaNN, Triton, etc.).
  • Ability to work closely with backend teams to deploy models in distributed systems.
  • Excellent problem-solving skills and comfort working on ambiguous, high-impact problems.



Preferred Qualifications

  • Experience with conversational AI, chat-based retrieval, or multi-turn dialog modeling.
  • Experience in media, streaming, sports data or large catalog discovery.
  • Knowledge of micro-drama, short-video personalization, or multi-objective recommendation systems.
  • Strong understanding of scalability patterns: batching, async orchestration, caching layers.



Why Join

  • Work on flagship launches (World Cup → IPL) impacting hundreds of millions of users.
  • Solve some of the most challenging problems in search, discovery, and conversational AI at scale.
  • Collaborate with a world-class team building foundational discovery platforms for India’s largest digital ecosystem.
