AI Engineer

Job Brief:
We are looking for an AI Engineer with a strong backend foundation and an AI-First development mindset. You will be responsible for designing, developing, and deploying production-grade AI systems. Unlike traditional roles where AI is an "add-on," you will treat AI as the primary operating model—architecting systems that are natively intelligent, adaptive, and scalable.
Key Responsibilities:

• AI-First Backend Development: Build robust, scalable backend services using Python (FastAPI/Flask/Django) that serve as the backbone for AI-driven applications.
• Model Implementation & Fine-tuning: Work deeply with Transformers and LLMs (GPT-4, Claude, Llama 3, Mistral). Fine-tune open-source models for specific domain tasks using frameworks like Hugging Face, PyTorch, or TensorFlow.
• Advanced RAG Pipelines: Design and optimize Retrieval-Augmented Generation (RAG) systems, implementing sophisticated retrieval strategies and integrating Vector Databases (Pinecone, Weaviate, Milvus, PGVector or Chroma).
• Agentic Workflows: Develop AI agents and multi-agent systems using frameworks like LangChain, LlamaIndex, Google ADK, BAML , Agno or CrewAI to automate complex reasoning tasks.
• Production MLOps: Own the end-to-end lifecycle of AI models, from experimentation to CI/CD deployment, monitoring for hallucinations, and optimizing for latency and cost.
• System Architecture: Design "AI-native" architectures that prioritize semantic search, embeddings, and context-aware data flows over traditional keyword-based logic.
• On-Prem Model Serving & Optimization: Deploy and manage open-source LLMs (Llama 3, Mistral, DeepSeek) using high-throughput serving engines like vLLM, SGLang, and Ollama.

Required Qualification & Technical Skills:

• Python Mastery: 4+ years of professional Python experience, including deep knowledge of asynchronous programming (asyncio), type hinting, and high-performance backend patterns.
• AI & NLP Core: Proven experience working with Transformer architectures, attention mechanisms, and tokenization.
• Vector Infrastructure: Hands-on experience with vector embeddings and similarity search optimization.
• Data Engineering: Proficiency in building data pipelines for AI, including data cleaning, ingestion, and prompt engineering.
• DevOps/MLOps: Strong experience with Docker, Kubernetes, and cloud platforms (AWS/GCP/Azure). Familiarity with GPU orchestration and model quantization techniques (GGUF, AWQ).

Soft Skills & "AI-First" Mindset

• Problem Solver: You don't just "plug in an API." You understand the underlying math and logic of why a model behaves a certain way.
• Iterative Builder: Comfortable with the non-deterministic nature of AI; you build with robust error-handling and fallback mechanisms.
• Communicator: Ability to explain complex AI trade-offs (e.g., latency vs. accuracy) to non-technical stakeholders.
   

Bonus Points

• Experience with LLM evaluation frameworks (RAGAS, DeepEval).
• Contributions to open-source AI libraries or research papers in NLP.
• Knowledge of Graph Databases (Neo4j) for GraphRAG implementations.
