Full job description

Lead Generative AI Engineer role requiring strong expertise in deep learning, transformer architectures, and building advanced GenAI applications beyond basic RAG systems. Responsibilities include building multimodal and agentic AI applications, designing AI workflows with reasoning and external integrations, developing knowledge graph-assisted AI systems, ensuring model safety and consistency, deploying scalable APIs and microservices using Python frameworks and Docker, monitoring ML systems on AWS/Azure/GCP, collaborating on CI/CD and MLOps pipelines, working with big data technologies like Apache Spark, Hadoop, and MongoDB, optimizing transformer-based models, implementing fine-tuning and model evaluation pipelines, developing information retrieval and predictive models, cross-functional collaboration, documentation, and mentoring junior engineers. Requirements include 5-6 years software development experience with ML model deployment, 2+ years deep learning and GenAI experience, advanced Python and backend framework skills, cloud platform expertise, big data knowledge, and strong mathematical foundations. The role supports a hybrid work model with minimum 2 days in office in Pune, Maharashtra, India.

What you'll do

  • Build conversational and non-conversational, multimodal, and agentic AI applications using LLMs and frameworks such as LangChain, LangGraph, LlamaIndex, AutoGen
  • Design AI workflows incorporating reasoning, planning, tool-use, memory, grounding, and external system integrations
  • Develop Knowledge Graph-assisted AI systems including entity extraction, linking, and KG-augmented retrieval
  • Ensure safety, consistency, and hallucination-control through structured evaluation and guardrails
  • Transform models into scalable APIs and microservices using Python, FastAPI/Flask, Docker
  • Deploy and monitor ML/AI systems in AWS/Azure/GCP optimizing for cost, latency, and reliability
  • Collaborate with MLOps teams on CI/CD pipelines, model versioning, monitoring, and automated evaluation
  • Work with big data technologies including Apache Spark, Hadoop, and NoSQL databases such as MongoDB
  • Build and optimize transformer-based and multimodal models using deep learning frameworks
  • Implement fine-tuning, alignment (RLHF/RLAIF), LoRA/QLoRA, pruning, and model evaluation pipelines
  • Develop information retrieval systems including hybrid dense–sparse retrieval, ranking, knowledge graphs, and relevance optimization
  • Build predictive models and ML pipelines from scratch including data preparation, feature engineering, and model selection
  • Work cross-functionally with CX, engineering, and product stakeholders to translate business needs into AI solutions
  • Document models, experiments, evaluation frameworks, and deployment processes
  • Mentor junior engineers and contribute to internal best practices, reusable components, and R&D initiatives

Requirements

  • Minimum 5-6 years of hands-on software development experience including building and deploying machine learning models into production
  • 2+ years of experience working with deep learning, GenAI, or transformer-based architectures
  • Demonstrated experience building GenAI applications beyond simple RAG (e.g., agents, multimodal, custom LLM fine-tuning)
  • Experience integrating AI systems in enterprise-grade environments
  • Advanced Python programming skills
  • Experience with API development and data engineering
  • Experience with backend frameworks such as Flask, FastAPI, Django
  • Knowledge of predictive modeling, deep learning, optimization, embeddings, vector search, model evaluation
  • Hands-on experience with cloud platforms AWS, Azure, or GCP for deploying and scaling AI systems
  • Experience with big data technologies including Apache Spark, Hadoop, and MongoDB
  • Strong understanding of data pipelines and large-scale processing
  • Mathematical foundations in linear algebra, probability, and statistics
  • Growth-oriented, collaborative, experimentation-driven mindset
  • Strong problem-solving skills with bias toward action
  • Ability to communicate complex concepts clearly to non-technical stakeholders
  • Open and flexible towards hybrid work structure with minimum 2 days in office
