How to become an LLM researcher: 16 beginner jobs open today

1. Know what the work is. An LLM researcher designs and trains large language models, the technology behind chat assistants. Beginner postings today use titles like Senior AI Infrastructure Engineer - Model Training; Large Language Model 연구 및 개발 Internship; ML Engineering Intern - LLM Research & Development; Internship, Foundation Models; (Senior) Machine Learning Scientist (LLM & Agents).
2. Learn the duties, not only the tools. Postings for this work describe what you will do more than which software you will use: read ten of them and list the duties that repeat.
3. Build proof you can show. Two or three results with a number, from a job, a course project or volunteer work. The kind of line a recruiter looks for: “Trained a ranking model in PyTorch that raised click-through on search results from 21% to 27% in an A/B test”.
4. Write the resume and the letter. Start from the LLM researcher resume example and the cover letter example, and replace every line with your own.
5. Apply where beginners are hired. 16 of today’s 136 open LLM researcher jobs are junior or intern roles or ask for two years of experience or less. See the open jobs and check each one with the resume match checker before you apply.

The step is the level word in the job title; “No level in the title” is usually the mid-level role. After senior, people move into lead, staff or principal roles, or into managing a team. What each level means.

• Build one piece of work you can show and talk about in an interview.
• Take one short course in the field and finish it with a project, not only a certificate.
• Keep a list of your results with numbers, updated every month: it becomes your resume lines and your interview stories.
• Find one person a few years ahead of you in this work and ask for a 20-minute talk each quarter.

• Headline: the title employers search for, then your strongest skills and one result: “LLM Researcher | [one result with a number]”.
• About: three short paragraphs: what you do, two results with numbers, what you want next.
• Skills section: list the skills postings name, in their words: Python, PyTorch, Machine Learning, LLM, AI.
• Open to work: set the job titles and places you want; recruiters filter by them.
