How to write a llm engineer resume
A strong LLM engineer resume shows depth on the model layer itself — fine-tuning (LoRA, RLHF), RAG architecture, structured outputs, evals, and inference optimization — with each bullet pairing the technique and a measured outcome (e.g. "LoRA fine-tuned Llama on 40K support conversations, beating the GPT-4 baseline on our eval set at 1/8th the serving cost"). Name specific models and frameworks; "worked with LLMs" matches nothing recruiters search.
What recruiters and ATS look for in a llm engineer resume
LLM engineer sits between AI engineer (application layer) and ML engineer (training infrastructure), and companies draw the line differently — so the resume must show which layer you actually own. Filters key on concrete technique nouns: LoRA, RLHF, quantization, distillation, RAG, function calling, evals, vLLM. The strongest signal is a decision story: why you fine-tuned instead of prompting, why you distilled instead of serving the big model — paired with the eval and cost numbers that proved it right. Coming from ML engineering, foreground any transformer work; coming from backend, foreground RAG and inference serving.
Section order: Summary → Experience → Projects (open-source or benchmarked side work) → Skills (grouped: Training / Serving / Evals) → Publications (if any) → Education.

LLM Engineer resume FAQ
An LLM engineer resume goes deep on the model layer — fine-tuning, quantization, serving, evals — while an AI engineer resume emphasizes shipping LLM-powered product features via APIs. The titles overlap and companies use them loosely, so mirror whichever framing the specific JD uses and lead with that layer of your experience.
No. Most LLM engineering work is fine-tuning, RAG, evals, and serving open-weight models — not pre-training. Pre-training experience only matters for frontier-lab roles. What JDs consistently ask for is evidence you improved a model against a real evaluation and served it economically.
Pair every technique with its measured result: eval score deltas, serving cost per million tokens, latency percentiles, and throughput. The pattern 'technique → benchmark → business number' (fine-tuned X, beat baseline by Y on our eval, cut cost Z%) is what separates practitioners from tutorial-followers.
The technique nouns: fine-tuning, LoRA, RLHF, RAG, quantization, distillation, vLLM, Hugging Face, PyTorch, evals. Spell them exactly — a recruiter searching 'LoRA' will not find 'low-rank adaptation methods'. List models you have genuinely worked with by name.
