Verbs that prove you shipped an LLM, not a prompt
Built, Shipped, Wired, Profiled, Authored. Junior LLM resumes that lean on 'experimented with GPT-4' read like notebook tourism. Open with verbs that show a running LLM in production.
Numbers anchor every LLM claim
p95 TTFT, JSON-validity rate, eval-pass rate, cost per 1M tokens, golden-trace count. 'Used GPT' without a metric reads like a hackathon poster. Numbers make the LLM real.
Connect every change to a measurable LLM outcome
Not 'used vLLM' but 'reaching 71 percent eval-pass rate on the internal eval set'. Every junior bullet should land with a measured outcome, not vibes.
Show feedback loops with people, not just frameworks
Senior LLM engineer, applied-science team, inference-platform reviewer. A junior LLM engineer who never feeds back to platform or science stays a notebook author.
Real LLM stack placed inside real artifacts
vLLM, Outlines, Instructor, Llama 3.1 8B, lm-eval-harness, LangSmith, Helicone. Naming the stack inside a deliverable proves you actually shipped the LLM.

Career Progression
LLM Engineer is one of the steepest emerging tech career arcs because the skill compounds across three axes simultaneously: stack depth (vLLM, TGI, Triton, Outlines, Axolotl), eval discipline (golden-trace replay, JSON-validity rate, hallucination rate (custom metric)), and cost-and-trust governance (per-1M-token cost ceilings, inference-trust posture). Most strong LLM engineers reach senior at frontier labs in five to seven years and head-of in nine to twelve, often pivoting from ML engineering, AI engineering, or systems-infra backgrounds.
Own one production LLM stack end-to-end through GA, including vLLM serving, structured-output gateway with Outlines, and a Braintrust or lm-eval-harness eval suite with at least 1,000 golden traces. Lead one explicit kill (prompt-only flow, open-temperature ad-hoc, vendor-only inference). Negotiate one per-1M-token cost ceiling with product or finance.
- Structured-Output Gateway Design
- Per-1M-Token Cost Governance
- Axolotl Fine-Tune Basics
- Quantization (fp8, INT4-AWQ)
Architect a multi-model serving fabric covering at least 6 model variants with measurable eval-pass rate held flat and cost-per-1M-tokens wins. Lead at least one strategic kill at runtime level. Author the LLM capability matrix or LLM-platform RFC adopted across teams. Influence at least one build-vs-buy decision on inference vendor or fine-tune tooling with a written memo.
- Multi-Model Serving Fabric
- Speculative Decoding Programs
- Cross-Org RFC Authorship
- Build-vs-Buy Memos
Own a portfolio of LLM runtime programs across multiple product surfaces. Negotiate a multi-year compute and inference commitment with vLLM, Together AI, Fireworks AI, or Anyscale. Stand up at least one governance structure (LLM Inference Council, LLM runtime lifecycle policy). Author the LLM engineer career ladder. Promote at least one mentee to senior IC.

Strong LLM engineers also pivot into Director of AI Engineering, Chief of Staff to a CTO at a frontier lab, AI safety research engineering, or operating partner roles at AI-focused venture funds. A common late-career move is founding an LLM-tooling startup (eval harnesses, structured-output gateways, fine-tune platforms, inference observability) or joining a frontier lab as a Principal LLM Engineer specializing in a single domain (open-weights serving, fine-tune pipelines, structured output, decoding research).
LLM Engineer resume templates and examples for every career stage. Whether you are wiring a first prompt-engineering and RAG flow, owning an eval-driven LLM stack with structured output and quantization, designing a multi-model serving fabric on vLLM, or running the LLM platform that the rest of the org bills against, your resume must prove you ship language-model systems with measurable JSON-validity rate, p95 TTFT, eval-pass rate, and cost per 1M tokens. Hiring panels at Anthropic, OpenAI, Cohere, Hugging Face, Mistral, Together AI, Fireworks AI, Anyscale, Databricks Mosaic, Notion AI, Glean, Perplexity, Cursor, Replit, and the Vercel AI SDK team filter out resumes that say 'used GPT' or 'integrated LLM' without an eval harness, a serving stack, or a per-1M-token cost number. This guide covers junior to lead resume strategies for LLM engineers with the specific stack (vLLM, TGI, Triton, llama.cpp, Outlines, Instructor, Guidance, lm-eval-harness, Braintrust, LangSmith, Helicone, Axolotl, Unsloth, TRL), the metrics that matter, and senior-coded language that gets loops at frontier LLM labs.
