  • Design, develop, and deploy Gen AI applications using LLMs and agentic frameworks (e.g., LangGraph, AutoGen, Crew AI).
  • Fine-tune open-source and proprietary LLMs using techniques like LoRA, QLoRA, and PEFT.
  • Build and optimize RAG pipelines with hybrid retrieval, semantic chunking, and vector search.
  • Integrate Gen AI solutions with cloud-native services (AWS Bedrock, Azure OpenAI, GCP Vertex AI).
  • Work with unstructured data (PDFs, HTML, audio, images) and multimodal models.
  • Implement LLMOps practices including prompt versioning, caching, observability, and cost tracking.
  • Evaluate model performance using tools like RAGAS, DeepEval, and FMeval.
  • Collaborate with product managers, data engineers, and UX teams to deliver production-ready solutions.
  • Mentor junior engineers and contribute to code reviews, design discussions, and best practices.

Requirements

  • Bachelor's degree in Computer Science, AI/ML, or related field.
  • 5-8 years of experience in software engineering or data science, with 2-3 years in Gen AI or LLM-based systems.
  • Strong Python programming skills and experience with ML/AI libraries (Hugging Face Transformers, LangChain, PyTorch).
  • Hands-on experience with vector databases (FAISS, Pinecone, Weaviate, Azure AI Search).
  • Familiarity with cloud platforms and Gen AI services (AWS, Azure, GCP).
  • Experience with REST API development (FastAPI, Flask) and containerization (Docker).
  • Solid understanding of AI governance, model safety, and prompt engineering.

Nice to Have

  • Exposure to agentic workflows and autonomous agents.
  • Experience with CI/CD pipelines and DevOps tools (GitHub Actions, Jenkins, Terraform).
  • Familiarity with front-end integration (React, Angular, TypeScript) and GraphQL APIs.
  • Knowledge of model interpretability, bias mitigation, and human-in-the-loop systems.
  • Experience with multimodal models and perception systems (e.g., vision + language).

Qualifications

  • No additional formal qualifications specified beyond the required degree and experience.

Benefits & Perks

  • Medical/Dental/Vision/Life Insurance
  • Long-term/Short-term Disability
  • Health and Dependent Care Reimbursement Accounts
