LLM engineer is a job title, not a job category, and a narrow one at that. Of 168,899 live AI-related postings Level tracks, only 6,263 carry the words LLM engineer, against 640 titled AI engineer and 652 titled machine learning engineer.
The number this article rests on: 6,263 of 168,899 live postings carry the title LLM engineer, the smallest of the three titles this page compares. Measured October 2026.
A rare title is still a real question with four honest answers: how many postings use it, whether it pays more than the nearby titles, which tools show up in them, and where the work sits on Level's four-level scale. Every answer below comes from the live catalogue, not from a course description or a hiring guide, and is re-measured every six hours.
How many jobs are titled LLM engineer?
6,263 live postings, out of 168,899 tracked across the whole catalogue. That is fewer than the 640 postings titled AI engineer and the 652 titled machine learning engineer, the two broader titles most LLM-focused work is filed under instead. Measured October 2026.
That gap does not mean LLM work itself is scarce, only that most of it is filed under a wider title. The pattern holds across the whole catalogue: a narrow, specific job title almost always trails the broader discipline it sits inside, and counting titles alone will undercount the underlying work by a wide margin. Anyone hiring or job-hunting for this exact skill set should read the AI engineer and machine learning engineer numbers as the fuller picture, not a separate market.
Does an LLM engineer get paid more than a machine learning engineer?
On 164 live LLM engineer postings that publish a USD range, the median maximum is $179,500. That sits below the $265,675 median maximum for machine learning engineer on 270 postings, and below the $251,104 figure for AI engineer on 160 postings. Measured October 2026.
Read this comparison as a live snapshot, not a fixed multiple. A median built on a small title-matched sample can move further from one refresh to the next than a median built on a broader population, so the gap between LLM engineer and its two neighboring titles is exactly the kind of figure that is worth re-checking rather than memorizing. What holds steady is the direction of the comparison across recent snapshots, more than the precise dollar spread.
What tools do LLM engineer jobs use?
None of the retrieval and serving tools this page tracks clear a single live posting this month, while LangChain, LlamaIndex, vLLM, Hugging Face, and pgvector do not clear the top 20 tools ranked this month. Measured October 2026.
This list only tracks tools already inside the top tools this catalogue names each month, so a tool that is common in practice but rare in posting text will not surface here. That absence is a measurement gap, not proof the tool is unused; postings describe requirements in plain language, and not every hiring manager names a specific library where a resume-screening tool or an applicant tracking system might otherwise catch it. Treat the tools that do appear as a floor on real demand, not a ceiling.
What Level is an LLM engineer job?
Level does not tag a title with a level directly; it rates what the posting text describes. Building with large language models is close to the definition of Builds AI (AI Level 4), where 7,363 of 168,899 live postings sit (4.4%), with a median maximum salary of $264,000 on 3,445 USD postings. Measured October 2026.
Level and title are two different measurements, and this page keeps them separate rather than assuming one predicts the other. Plenty of postings that never use the words LLM engineer still build AI, because the day-to-day work is building with models rather than calling a hosted API from the side. That is precisely why the title count above and the Builds AI count here should be read as complementary views of the same underlying market, not as competing answers to the same question.
