• Create intelligent pipelines for prompts, embeddings, and feedback loops

• Optimize GenAI systems for performance, modularity, and low-latency inference

• Collaborate with ML engineers on agentic components like Tool Agents and LLM Gateways

• Debug, profile, and improve GenAI applications across the stack

• Maintain high-quality documentation for AI services and deployment workflows

✅ What We're Looking For

1. 5+ years of IT experience
2. 1+ years hands-on with GenAI (LLMs, RAG, embeddings, fine-tuning, or prompt engineering)
3. Strong software engineering skills in Python (preferred), Java, or Scala
