Overview

We're looking for a seasoned Data Scientist who can take machine learning models from idea to production. You'll work across the full stack—building, training, and deploying Generative AI and LLM solutions on GCP/Azure/AWS, backed by solid engineering practices like CI/CD and API design. This hybrid role is based in Chennai, Bangalore, Pune, or Coimbatore.

What You'll Do8

  • 1Design, train, and fine-tune ML and Generative AI models using techniques like RAG, embeddings, and LLM integrations.
  • 2Develop production-grade microservices and APIs with Python and FastAPI, ensuring they are scalable and maintainable.
  • 3Deploy and manage ML workloads on cloud platforms such as GCP, Azure, or AWS.
  • 4Build and optimize CI/CD pipelines (using Jenkins or GitHub Actions) for ML pipelines and containerized microservices.
  • 5Apply solid Object-Oriented Programming principles to write clean, modular, and reusable code.
  • 6Lead cloud migration and modernization efforts for ML platforms and infrastructure.
  • 7Collaborate closely with Product, Data Engineering, and Infrastructure teams to align on solution architecture and delivery.
  • 8Implement robust API management and integration strategies to connect ML services with other systems.

Requirements5

  • 1At least 7+ years of hands-on experience in data science and Python development, with a strong focus on production-level code.
  • 2Deep expertise in Generative AI and Large Language Models—from prompt engineering to fine-tuning and deployment.
  • 3Proven ability to design and develop APIs using FastAPI and apply OOP patterns for maintainable software.
  • 4Experience deploying ML solutions on at least one major cloud provider (GCP, Azure, or AWS), including CI/CD tooling like Jenkins or GitHub Actions.
  • 5Nice-to-have: familiarity with Docker/Kubernetes and vector databases such as Pinecone, FAISS, or Chroma.

Who Should Apply

This role is ideal for a data scientist who leans toward the engineering side—someone who enjoys building robust, scalable systems around models rather than just experimenting in notebooks. You should be comfortable owning the full lifecycle of ML solutions, from model development to cloud deployment and monitoring. If you have deep experience with Generative AI and LLMs, and you thrive in a collaborative, cross-functional environment, we'd love to hear from you.
