Where to Place Keywords in a LLM Engineer Resume

ATS systems give extra weight to keywords that appear in specific sections. Use this simple placement strategy:

  1. Headline / summary: Include LLM Engineer plus 2–3 core skills (Large Language Models, Fine-Tuning, RAG).
  2. Skills: Group hard skills and tools; keep soft skills (Communication, Teamwork, Problem Solving) short.
  3. Experience bullets: Each of your top 3 skills should appear in at least one quantified bullet.
  4. Education / certs: Only add credential keywords that are required or strongly preferred in the posting.
  5. Use both spelled-out terms and acronyms when the LLM Engineer posting mixes both.
  6. Weave keywords into achievement bullets—never dump them in a keyword cloud.

  • Hiding important keywords in graphics, tables, or icons ATS can't read.
  • Copy‑pasting entire job descriptions instead of tailoring authentic bullets.
