AI Engineer Roadmap: Building LLM-Powered Apps

HireAI Career TeamPublished: Mar 04, 20269 min read

What Does an AI Engineer Do?

Unlike ML researchers who train models from scratch, AI Engineers integrate frontier LLMs (Gemini, Claude, GPT) into production software systems: 1. Prompt Engineering & Structured Outputs: JSON schemas and tool/function calling. 2. Advanced RAG: Chunking strategies, semantic routing, and re-ranking models. 3. Autonomous Agent Loops: Multi-step tool use, memory persistence, and reflection. 4. Evaluation & Guardrails: Continuous bench testing against hallucinations using frameworks like Ragas or TruLens.
