AI Engineer vs LLM Engineer:
Same Role, Different Names?
The AI job market is full of overlapping titles.
Understanding what companies actually mean saves you from chasing phantom distinctions.
Title Confusion Is Real.
Don't Overthink It.
You see both titles in job postings and wonder if you're missing some important distinction between them.
Recruiters use these terms interchangeably, making it hard to know what skills each role actually requires.
You're optimizing your resume for one title when the other might get you the same jobs.
Here's What Companies Actually Mean
The World-Class AI Engineer Cohort
In most cases, AI Engineer and LLM Engineer refer to the same role. The distinction, when it exists, is about scope and specialization.
Usually the Same
90% of the time, these titles describe the same job: building applications with LLMs and AI APIs
When LLM Engineer Differs
Some companies use 'LLM Engineer' specifically for model fine-tuning, optimization, or working closer to model internals
Read the Job Description
The title matters less than the actual requirements. Focus on what they're asking you to build.
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 is the difference between AI engineer and LLM engineer?
In practice, minimal to none. Both titles typically describe engineers who build applications using large language models, work with AI APIs, implement RAG systems, and deploy AI-powered features. The 'AI Engineer' title is more established and broader. 'LLM Engineer' is newer and explicitly references the technology, but the job is usually the same. Some companies use 'LLM Engineer' for roles focused on model fine-tuning or optimization, but this is inconsistent.
Are AI engineer and LLM engineer the same role?
Usually, yes. Most job postings use these titles interchangeably. Both involve: working with LLM APIs (OpenAI, Anthropic, Google), building RAG systems, implementing AI agents, deploying to production, and monitoring AI applications. If you're qualified for one, you're typically qualified for the other. The title choice often reflects the company's branding or the hiring manager's preference, not a meaningful role distinction.
When do these roles actually differ?
In a minority of companies: 'LLM Engineer' may focus specifically on model-level work—fine-tuning, optimization, evaluation, or working with open-source models. 'AI Engineer' may be broader, including computer vision, audio, or other AI domains beyond language models. If the job description mentions model training, RLHF, or deep optimization work, that's a signal the LLM Engineer role differs from typical AI Engineering. Otherwise, assume they're the same.
Which title should I use on my resume?
Use 'AI Engineer' for broader appeal—it's the more established title and applies regardless of which specific AI technologies you work with. If you're targeting roles specifically focused on language models at LLM-focused companies, 'LLM Engineer' signals domain specialization. Many engineers list both: 'AI/LLM Engineer' to match both search terms. Let the job posting guide your resume customization.
Should I apply to both AI Engineer and LLM Engineer positions?
Absolutely. Apply to both since they usually describe the same role. Read each job description to confirm the requirements match your skills, but don't filter by title alone. Some companies posting 'LLM Engineer' roles will interview candidates with 'AI Engineer' experience and vice versa. The skills transfer completely between these title variations.
Do AI engineers and LLM engineers earn different salaries?
No meaningful difference. Both roles typically range from $130K-$250K depending on experience, location, and company. Since they're usually the same job with different names, compensation is driven by your experience and negotiation skills, not which title appears on the offer letter. Focus on building skills and demonstrating impact, not chasing one title over another.
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 become job-ready?
3-6 months with an existing software engineering background. You're learning to work with LLM APIs, build RAG systems, and deploy AI applications. If you're new to programming, add time for Python and software engineering fundamentals. The path is the same regardless of which title you're targeting.
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.
