AI Application Engineer

We are looking for a technically adept and instructionally strong AI Developer with coreexpertise in Python, Large Language Models (LLMs), prompt engineering, and vector searchframeworks such as FAISS, LlamaIndex, or RAG-based architectures. The ideal candidatecombines solid foundations in data science, statistics, and machine learning development with ahands-on understanding of ML DevOps, model selection, and deployment pipelines.3–4 years of experience in applied machine learning or AI development, including at least 1–2years working with LLMs, prompt engineering, or vector search systems.

Core Skills Required

• Python: Advanced-level expertise in scripting, data manipulation, and model development
• LLMs (Large Language Models): Practical experience with GPT, LLaMA, Mistral, or open-
  

source transformer models

• Prompt Engineering: Ability to design, optimize, and instruct on prompt patterns for various
  

use cases

• Vector Search & RAG: Understanding of feature vectors, nearest neighbor search, and
  

retrieval-augmented generation (RAG) using tools like FAISS, Pinecone, Chroma, or
Weaviate

• LlamaIndex: Experience building AI applications using LlamaIndex, including indexing
  

documents and building query pipelines

• Rack Knowledge: Familiarity with RACK architecture, model placement, and scaling on
  

distributed hardware

• ML / ML DevOps: Knowledge of full ML lifecycle including feature engineering, model
  

selection, training, and deployment

• Data Science & Statistics: Solid grounding in statistical modeling, hypothesis testing,
  

probability, and computing concepts

Responsibilities

• Design and develop AI pipelines using LLMs and traditional ML models
• Build, fine-tune, and evaluate large language models for various NLP tasks
• Design prompts and RAG-based systems to optimize output relevance and factual grounding
• Implement and deploy vector search systems integrated with document knowledge bases
• Select appropriate models based on data and business requirements
• Perform data wrangling, feature extraction, and model training
• Develop training material, internal documentation, and course content (especially around
  

Python and AI development using LlamaIndex)

• Work with DevOps to deploy AI solutions efficiently using containers, CI/CD, and cloud
  

infrastructure

• Collaborate with data scientists and stakeholders to build scalable, interpretable solutions
• Maintain awareness of emerging tools and practices in AI and ML ecosystems
  

Preferred Tools & Stack

• Languages: Python, SQL
• ML Frameworks: Scikit-learn, PyTorch, TensorFlow, Hugging Face Transformers
