LLM Engineer Career
The Definitive Guide
LLM engineering is the hottest AI career path with $150K-$250K+ salaries.
Here's what the role actually involves and how to get there.
The Title Is New.
The Path Is Unclear.
LLM Engineer is everywhere, but nobody agrees on what the role actually requires.
Skills range from prompt engineering to fine-tuning to infrastructure. What matters most?
Without a clear path, you risk learning the wrong things.

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.

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."

Frequently Asked Questions
What does an LLM engineer actually do?
LLM engineers build applications powered by large language models. Day-to-day: designing prompt strategies, implementing RAG systems, building LLM-powered features, fine-tuning models for specific use cases, optimizing latency and cost, and deploying LLM applications to production. It's more engineering than research. You're not training GPT, you're building useful things with it.
What skills do LLM engineers need?
Core: Python, prompt engineering, LangChain/similar frameworks, RAG implementation, vector databases, LLM APIs (OpenAI, Anthropic). Production: streaming, caching, rate limiting, cost optimization, evaluation. Advanced: fine-tuning, model selection, multi-model architectures. Most LLM engineers are software engineers first, with specialized LLM knowledge layered on top.
How much time will this take?
You'll spend 3 hours every Tuesday in the live session and roughly 3 hours of async work in between, for 8 weeks. The Tuesday session time is fixed.
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.
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.
