About This Role

What you will own and the impact you can make in this role.

We are looking for skilled and experienced AI/ML Engineers with hands-on expertise in predictive modeling, Machine Learning, Large Language Models (LLMs), Generative AI, RAG pipelines, and agent-based systems. The ideal candidate should be capable of designing, developing, deploying, and optimizing scalable AI solutions for real-world business use cases. The role requires strong programming skills, practical experience with modern ML frameworks, and hands-on exposure to LLM fine-tuning and intelligent agent workflows.

Roles & Responsibilities

  • • Build, train, evaluate, and deploy predictive machine learning models.
  • • Design and develop LLM-powered applications and intelligent AI agents.
  • • Build and implement Retrieval-Augmented Generation (RAG) pipelines.
  • • Fine-tune Large Language Models using PEFT, LoRA, and QLoRA techniques.
  • • Perform feature engineering, data preprocessing, model training, and performance evaluation.
  • • Work with vector databases for efficient document retrieval and semantic search.
  • • Design and develop multi-step agent workflows for complex problem-solving.
  • • Integrate AI solutions with APIs, applications, and business workflows.
  • • Optimize AI/ML models and applications for scalability, accuracy, and performance.
  • • Collaborate with cross-functional teams including software developers, data engineers, product teams, and business stakeholders.
  • • Stay updated with emerging technologies and best practices in Machine Learning, Generative AI, LLMs, and agent-based systems.
