Job description

We’re looking for a motivated Junior Generative AI Developer to join our newly launched IT Pod project. This is a hands-on individual contributor role where you’ll collaborate with senior engineers to design, implement, and optimize cutting-edge Generative AI solutions. You’ll work with technologies like LLMs (GPT-4, Claude, Gemini), diffusion models, and multimodal systems — all while following ethical AI practices.

Job requirements

1.Model Development & Fine-Tuning

  • Assist in training and fine-tuning generative models (text, image, code) using PyTorch, TensorFlow, or JAX

  • Implement RAG (Retrieval-Augmented Generation) pipelines and optimize prompts for specific domains

2. Tooling & Integration

  • Build applications using LangChain, LlamaIndex, Hugging Face Transformers

  • Integrate GenAI APIs (OpenAI, Anthropic, Mistral) into enterprise workflows

3. Prompt Engineering

  • Design and test advanced prompting strategies (few-shot, chain-of-thought, ReAct)

  • Create reusable prompt templates for workflows like customer support, code generation, and content moderation

4. Evaluation & Optimization

  • Develop metrics for hallucination reduction, output consistency, and safety alignment

  • Optimize inference costs using quantization, distillation, or speculative decoding

5. Collaboration

  • Work with cross-functional teams (product, data, UX) to deploy AI solutions

  • Document processes and contribute to knowledge-sharing sessions

  • Experience with deployment tools (FastAPI, Docker, MLflow)

AI/GenAI Exposure:
Experience with at least two of the following:

  • Hands-on projects with LLMs or diffusion models

  • Vector databases (Pinecone, Milvus) and orchestration tools

  • Fine-tuning LLMs (Llama 2, Mistral) using LoRA, QLoRA, RLHF

  • Building RAG pipelines with embedding models (BERT, OpenAI)

  • Developing applications with Stable Diffusion, DALL·E

  • NLP projects using spaCy or NLTK

Soft Skills:

  • Strong problem-solving mindset and curiosity about emerging AI trends

  • Ability to explain technical concepts to non-technical stakeholders
