What LLM engineers actually build

Five categories of production systems — this bootcamp covers all of them.

LLM engineering is not prompt engineering. It's the full-stack discipline of building, deploying, evaluating, and operating AI applications that use large language models as their core.

🔍

RAG Systems

Retrieval-Augmented Generation — connecting LLMs to your own documents, databases, and knowledge bases so they answer questions based on real private data.

Lesson 2 — full lesson
🤖

AI Agents

Autonomous systems that use LLMs to plan, reason, and take actions — calling APIs, browsing the web, writing and executing code, managing files, and completing multi-step tasks.

Lesson 5 — full lesson
🧬

Fine-Tuned Models

Custom-trained versions of open-source or commercial models adapted to a specific domain, persona, or task — using LoRA, QLoRA, RLHF, and DPO techniques.

Lesson 4 — full lesson
📐

Evaluation Pipelines

Automated systems that measure LLM application quality — hallucination detection, factuality scoring, bias evaluation, and continuous A/B testing in production.

Lesson 6 — full lesson

Production LLM APIs

Scalable, observable, cost-optimized inference infrastructure — caching, rate limiting, multi-provider routing, latency optimization, and SLA-backed LLM endpoints.

Where this leads

LLM / AI Engineer salary benchmarks — 2026.

LLM engineers are among the fastest-rising AI specialisations in 2026 — the global AI market hit $900B and companies are racing to hire engineers who can ship LLM products that actually work in production. Figures below are gross annual base salary. Select a country.

Junior LLM / AI Engineer
€65,000–€85,000
gross/year · 0–2 yrs, strong Python + LLM project portfolio

Entry-level LLM roles require practical portfolio work — a deployed RAG system, a working agent, or a fine-tuned model matters more than certifications. Glassdoor Germany ML Engineer range: €57–93.4K (n=510, June 2026). LLM specialisation commands a premium above the standard ML Engineer band. Berlin and Munich lead in junior AI job density.

LangChainRAGOpenAI APIPython

Junior LLM / AI Engineer
€60,000–€80,000
gross/year · 0–2 yrs, strong Python + LLM project portfolio

Brussels, Antwerp, and Ghent are the primary Belgian markets. EU institutions in Brussels and regulated sectors (pharma, banking) are creating LLM engineering demand for compliance-aware AI applications. Belgian income tax (~50%) significantly reduces net take-home compared to equivalent German or Dutch roles at the same gross level.

Many Belgian AI engineers work as B2B contractors/freelancers to reduce the tax burden. Alcor data shows Belgian lead AI engineers reaching $12,400/month (~€148K/yr) at top of market — this likely reflects total contractor rates. Strong enterprise demand from Belgian banks (KBC, Belfius), pharma (UCB, Johnson & Johnson EU), and the large consulting sector (Deloitte, Accenture) deploying LLM solutions.

Is this for you

Beginner tier — no prior IT knowledge required at all.

This is the only Beginner-tier bootcamp in the SelfMagister catalogue. It assumes nothing. If you've never written code professionally and want to build AI applications, this is where you start.

This is for you

You have zero professional IT or ML background and want to learn LLM engineering from the ground up

You've used ChatGPT or Claude and want to understand how to build things like them, not just use them

You want to build RAG systems, AI agents, or fine-tuned models — and need to learn everything required to do that from scratch

You're a software developer or product manager who wants to add LLM engineering skills to what you already know

You want material that's still useful on the job — not just to get past an interview, but to actually build systems that work in production

You learn better reading and building at your own pace than attending scheduled classes

This is probably not for you

You're looking for a pure machine learning theory course — this is about building and operating LLM applications, not ML research

You want to learn Python, JavaScript, or a programming language from zero — this teaches LLM engineering concepts, not a language curriculum

You need live instruction, pair programming sessions, or a cohort to keep you accountable — this is entirely self-paced written material

You're looking for video walkthroughs — everything here is written and structured for deep reading, not watching

You want a certification exam prep guide — this teaches the actual engineering skills, not how to pass a specific exam

Never stuck, never alone

Every lesson ships with Mentor Bob.

Self-paced doesn't mean unsupported. Mentor Bob is an AI study assistant built into every section — it already read whatever you're reading, so you can ask it to clarify a concept or give you a different example the moment you get stuck.

  • Reads the exact section you're on before you even ask
  • Explains a concept a different way, or with a fresh example
  • Sitting in the corner of every lesson, every chapter, 24/7

— Included free with the bootcamp, not an upsell.

MENTOR BOB — INSIDE LESSON 5 · CHAPTER 3

YOU

Why does my agent keep calling the same tool in a loop instead of finishing?

BOB

That's almost always a missing stop condition or a tool result the model can't parse as "done" — walk through your agent's loop logic from this section and check what signal it's actually waiting for.

Stop using AI. Start building it.
