Job description

Description :

Mandatory Requirements :

  • Minimum 5+ years of experience in designing, developing, and deploying Machine Learning / Deep Learning systems in production.
  • Strong hands-on experience with Python and deep learning frameworks such as PyTorch, TensorFlow, or JAX.
  • At least 1 year of experience in fine-tuning Large Language Models (LLMs) using LoRA / QLoRA and building RAG (Retrieval-Augmented Generation) pipelines.
  • Practical experience with MLOps and production-grade systems including Docker, Kubernetes, Spark, model registries, and CI / CD workflows.

Preferred Requirements :

  • Prior experience in open-source GenAI contributions, applied LLM / GenAI research, or large-scale production AI systems.
  • B.S. / M.S. / Ph.D. in Computer Science, Data Science, Machine Learning, or a related technical field.

    • Role and Responsibilities :

  • Lead end-to-end machine learning lifecycle activities including model design, training, evaluation, deployment, and scaling.
  • Build and manage production-ready ML pipelines with CI / CD, monitoring, testing, and model drift detection.
  • Fine-tune LLMs and implement RAG-based systems for enhanced retrieval and reasoning.
  • Design and develop agentic workflows for planning, reasoning, and decision-making.
  • Create both real-time and batch inference systems using Docker, Kubernetes, and Spark.
  • Utilize advanced architectures such as transformers, diffusion models, RLHF, and multimodal systems.
  • Work collaboratively with engineering and product teams to integrate AI models into production applications.
  • Mentor junior team members and promote best practices in scalable ML systems, MLOps, and responsible AI.

    • Ideal Candidate Profile :

  • Proven experience in production-grade ML / DL system design and deployment.
  • Expertise in LLM fine-tuning, RAG pipelines, and vector search tools (e.g., Weaviate, PGVector).
  • Strong software engineering background with knowledge of APIs, version control, and testing.
  • Familiarity with agent-based development approaches (e.g., ReAct agents, orchestration, function-calling).
  • Ability to balance research innovation with production scalability.
  • Additional advantage for open-source contributions, GenAI research, or large-scale applied systems.

    • Location Options : Mumbai / Bengaluru / Hyderabad / Gurugram

    Experience Required : 5 - 12 Years

    Working Days : 5 Days / Week (Hybrid - 3 Days WFO)
