Why This Resume Works

Verbs that signal research-to-prod ownership

Reproduced, Authored, Profiled, Extended, Implemented. Frontier labs scan for verbs that prove you can take a paper and turn it into runnable training code, not just 'used PyTorch'. This is the bar that separates research engineers from generic MLEs.

Eval and training-run numbers, not vibes

Within 0.6 points of HumanEval pass@1, 38 ablation runs, 17% of GPU-hours, 1.7x throughput. Research engineers are judged on benchmarked deltas; without the number, your ablation is folklore.

Rigor and FLOPs discipline visible in every bullet

Not 'trained a model' but 'across 3 distilled model sizes' and 'the 4 settings that survived golden-trace eval replay'. Frontier labs hire for rigor: ablations that prove a hypothesis, not training runs that burn compute. This is the part MLE-flavored CVs always miss.

Collaboration signal, even at intern level

In pair with two senior research engineers; landed in 3 internal training stacks. Even as an intern, prove you ship into shared codebases that other researchers depend on. This is NOT an MLE role; it is a paper-to-codebase role with peer reviewers.

Stack named at the layer a frontier lab cares about

Triton kernel, FSDP-Z2 sharding, golden-trace replay, EleutherAI lm-evaluation-harness. Do not write 'PyTorch'; write the specific layer of the training stack you touched. That is how research-engineer recruiters tell hobbyists from contributors.

Career Progression

AI Research Engineering is one of the highest-leverage tracks in frontier labs. Progression goes from ablation-owner / eval-harness contributor (junior) to small-model training-run lead (middle) to large-model training-run-tier lead (senior) to research-area architect (lead, MTS, staff). Each level adds compute scale, eval-suite ownership, and reusable artifacts. The ceiling for ICs is staff or principal research engineer; many leads also pivot to research-engineering management (head of pretraining, head of post-training).

  1. JuniorMiddle1-3 years

    Reproduce 2-3 frontier-lab papers with named eval deltas, contribute one merged PR to lm-evaluation-harness / trl / vLLM, own a small-model ablation series end-to-end, profile and report GPU-hour cost, ship one Triton kernel or NCCL-tuning fix, and start being the named on-call for at least one secondary training run.

    • FSDP-Z3 + activation checkpointing
    • SFT and DPO post-training
    • Triton kernel authoring
    • Eval-harness golden-trace replay
    • FLOPs accounting
  2. MiddleSenior2-4 years

    Be primary on-call for a real training run (>=7B parameters) with a reliability percentage, kill at least one multi-week ablation with named eval evidence, mentor 2 juniors through their first ablation-owner rotations, author a reusable artifact (post-training run-book, eval template, kernel pack), and start influencing the eval-harness contract used by adjacent teams.

    • RLHF and RLAIF post-training
    • NCCL collective tuning
    • Tensor parallel + pipeline parallel
    • Speculative decoding stacks
    • Reusable run-books
  3. SeniorLead3-5 years

    Own a frontier-tier training run (4-digit GPU count, 70B+ parameters, multi-week duration), produce a senior-only kill (multi-week initiative stopped after eval ablation, hundreds of thousands of GPU-hours redirected), mentor 2 ICs to research-engineer senior, author a company-wide eval-harness contract or FLOPs accounting library, and partner with a VP-level peer on the research-area roadmap.

    • Research-area architecture (post-training, inference-time compute, multimodal alignment)
    • Multi-million GPU-hour budget ownership
    • Eval-harness contract design
    • Promotion ladder design and IC rotation mechanisms
    • Cross-team partnerships with VP-level peers

Adjacent paths: research scientist (more publications, less code), MLE / production AI engineer (serving and infra at scale), mech-interp researcher (specialized branch of the field), research-engineering manager (people leadership), inference-systems engineer (vLLM / TensorRT / speculative decoding specialist). Some research engineers also pivot to AI safety / red-team-specific roles or to founding research-tooling startups (eval platforms, training-stack tooling).

AI Research Engineer CV templates and examples from intern to lead, written for the actual frontier-lab job spec. The role lives between the research scientist and the production MLE: you turn papers into runnable training and inference code, own the eval harness, run ablations, and ship frontier-model components. Recruiters at Anthropic, OpenAI, Google DeepMind, FAIR, NVIDIA Research, Cohere, and Apple AIML scan for very specific signals: paper-to-checkpoint turnaround, training-run reliability percentages, eval-suite pass rates on MMLU, GPQA-Diamond, HumanEval and MATH-500, FLOPs efficiency, GPU-hour cost discipline, and the discipline to kill ablations that fail to lift evals. This guide covers junior to lead with concrete metrics, the tools that matter (PyTorch, JAX, FSDP, DeepSpeed ZeRO, Megatron-LM, Triton, RLHF, DPO, golden-trace replay), and the wording that separates research engineers from generic ML engineers.

Frequently Asked Questions

AI Research Engineers turn research papers into runnable training and inference code, run ablations, own the eval harness, and ship frontier-model components. They sit between research scientists (who frame the hypothesis) and applied-AI / MLE engineers (who productionize models for users). Day to day they author training recipes, tune FSDP / tensor-parallel / activation-checkpoint settings, write Triton or CUDA kernels for hot paths, run hundreds of ablations against named eval suites (MMLU, GPQA-Diamond, HumanEval, MATH-500), kill experiments that fail to lift evals, and write the post-mortems and run-books other research teams reuse.

MLE / applied-AI engineers own production systems: serving infrastructure, RAG pipelines, latency, uptime, model deployment. AI Research Engineers own training quality, eval harnesses, ablation rigor, FLOPs efficiency, and the kernels and parallelism strategies that make a frontier-scale training run finish without crashing. The MLE bullet is 'p99 latency 180ms at 50M req/day'. The research-engineer bullet is '94% wall-clock-without-crash on 4096 H100s at 70B parameters via FSDP-Z3 + selective activation checkpointing'. Both are valid careers; recruiters reject CVs that confuse them.

No. The AI Research Engineer role is intentionally distinct from research scientist; many ICs at Anthropic, OpenAI, DeepMind, FAIR, and Cohere joined with a strong MS plus open-source contributions. PhDs are common at senior+ but not required. What matters: a reproduction of a recent paper, a merged PR to lm-evaluation-harness / trl / vLLM / a Triton kernel, named eval deltas, and FSDP-based training experience. Senior+ research-engineer levels increasingly expect PhD or equivalent industry depth (5+ years in a frontier-adjacent training stack).

MMLU (knowledge), GPQA-Diamond (graduate-level reasoning), MATH-500 (math), HumanEval / MBPP / LiveCodeBench (code), AIME (competition math), BBH (Big-Bench Hard), and increasingly task-specific evals like SWE-bench (agent). State the shot count (e.g. 5-shot MMLU, 0-shot GPQA-Diamond) and either an absolute number or a delta against a named baseline. Generic 'evaluated on benchmarks' is a CV killer; a research engineer's eval choices are themselves a signal of what the role you came from cared about.

Pick one paper from a frontier lab in the last 12 months and reproduce its training recipe in a real FSDP-based stack. Run at least 30 ablations, measure deltas on a named eval (MMLU, GPQA-Diamond, HumanEval), and ship a merged open-source PR (lm-evaluation-harness extension, a trl recipe, a Triton kernel, a vLLM optimization). One reproduction with a real eval delta and a real PR is more credible than ten Coursera certificates.
