Here's How RAG Engineering Fits Into AI
The World-Class AI Engineer Cohort
RAG engineering is a growing specialization within AI engineering. It focuses on the intersection of search, retrieval, and language models—a critical skill as enterprises adopt AI.
RAG Engineer Focus
Vector databases, embeddings, chunking strategies, hybrid search, and retrieval optimization
AI Engineer Focus
Broader scope including AI agents, prompt engineering, various LLM applications, and full AI system design
The Relationship
RAG engineering is a specialization within AI engineering—every AI engineer should understand RAG
Meet Your Mentor
My aim has been the same for years: become a world-class AI engineer. Every career move I've made has been measured against that.
I started as a software tester on a $500/month internship in the Netherlands. Taught myself to code, learned to ship real systems, and worked my way to Senior Engineer at GitHub.
Then I left GitHub. I joined an AI research lab as Member of Technical Staff, where I currently build products for secure AI monitoring.
The cohort draws directly from my real experience so you can make progress fast.
I run this special cohort with only a few people because hands-on work with me is what it takes to bring you to become a world-class AI engineer.
Real Results
Vittor
AI Engineer
Built and deployed his portfolio piece, then landed the AI role
"The coaching played a huge part in my success. I focused on AI fundamentals, the certification path, and soft skills like professional writing. Having access to expert guidance gave me confidence during interviews and helped me feel I was on the right path.
I built my own platform (simple but functional) and deployed it on AWS. I used it in my portfolio and showcased it during interviews. The way complex topics were explained, especially the restaurant analogy for AI systems, really stuck with me. Focusing on doing the basics well was absolutely essential."

RAG Systems Are Everywhere. Specialists Are Rare.
Frequently Asked Questions
What is the main difference between RAG engineers and AI engineers?
RAG engineers specialize deeply in retrieval-augmented generation systems—they focus on embeddings, vector databases, chunking strategies, hybrid search, reranking, and retrieval evaluation. AI engineers have broader scope, working on various LLM applications, AI agents, prompt engineering, and general AI system design. RAG is a critical skill for AI engineers, but RAG engineers go deeper on the retrieval and search components.
Is 'RAG Engineer' a real job title in 2026?
Yes, it's becoming one. As companies deploy enterprise AI systems, they need specialists who understand knowledge retrieval deeply. You'll see titles like 'RAG Engineer,' 'Knowledge Systems Engineer,' or 'AI Search Engineer.' These roles focus on making AI systems answer questions accurately using company knowledge bases. The specialization emerged because RAG implementation is harder than it looks—poor retrieval ruins entire AI systems.
Do RAG engineers earn more than general AI engineers?
Specialists often earn premiums. RAG engineers at companies with complex knowledge bases can earn 10-15% more than generalist AI engineers because the skill is scarce and critical. In 2026, senior RAG specialists earn $160K-$220K while generalist AI engineers earn $140K-$200K at similar levels. However, generalist AI engineers have more job options across different types of companies.
Is it worth specializing in RAG versus staying a generalist AI engineer?
It depends on your interests and market. RAG specialization makes sense if: you enjoy search and retrieval problems, you want to work at enterprises with large knowledge bases, or you find the technical challenges of retrieval optimization engaging. Stay a generalist if: you want maximum job flexibility, you enjoy building diverse AI applications, or you're early in your AI career. Many engineers build RAG expertise as part of their AI toolkit without exclusively specializing.
What skills define a RAG engineer?
Deep expertise in: vector databases (Pinecone, Weaviate, Chroma, pgvector), embedding models and selection, chunking and document processing strategies, hybrid search (combining vector + keyword), query understanding and rewriting, retrieval evaluation metrics (relevance, recall), reranking models, and production RAG architecture. RAG engineers also need strong Python, API development, and understanding of LLM integration.
What's the career path for RAG engineers?
RAG specialization can lead to: Senior RAG Engineer, Knowledge Systems Architect, AI Search Lead, or AI Infrastructure roles. You can also transition to broader AI leadership since RAG expertise is valued across AI teams. The specialization is especially valuable at enterprises building internal AI systems—companies like law firms, healthcare organizations, and financial services that need AI to work with their documents.
I've signed up for cohorts before and dropped out. How is this different?
It probably isn't, and you should hold the money. Most cohort dropouts are people who couldn't articulate what they were shipping when they signed up. That's why the consult exists, and why I turn down most applications. If we get on the call and you can't tell me what you'll have shipped at the end of week 8, I'll point you to the AI Native Engineer community until you can.
I'm not pivoting careers. I want to build a product. Does this still work?
Yes, the cohort works for people shipping their first serious AI system whether the goal is to land a senior role or to launch a product. The shipped system serves both equally well.
Do I need prior AI experience?
You need to be able to code in Python or TypeScript. Complete beginners can follow the classroom they get access to before the cohort sessions to come in well-prepared.
How long does it take to develop RAG specialization?
With AI engineering experience: 2-4 months to develop deep RAG expertise. Focus on: vector database internals (not just APIs), embedding model selection and fine-tuning, advanced chunking strategies, hybrid search implementation, and retrieval evaluation. Build several RAG systems with different architectures to understand trade-offs. The learning curve is manageable because you're going deeper on concepts you already use.
What does it cost?
It's a four-figure investment that we discuss during the 30-minute consult, alongside whether the cohort is the right fit for your project.
Can I do this while working full-time?
Yes, most attendees do. The live session is one Tuesday a week and the async work fits around your existing schedule, as long as you can carve out roughly 6 hours a week.
I accept those who have the highest chance of success.
In the 30-minute call we discuss your goals and whether you are ready for the program.
