AI Research Engineer
You build and run the experiments researchers design — training the models, not writing the papers.
Degree usually expected Hard, and the bar is implementation depth rather than novelty.
Can I actually do this?
Not an entry role. Of the three research-facing paths here it has the lowest barrier, because it is judged on engineering rather than publications — that is our reasoning from what the role assesses, not a hiring source we have checked. A PhD is common but not universal; demonstrated ability to reimplement papers is the substitute.
Who it suits. Strong engineers who want to work near research without needing to originate it — you make other people's ideas run, correctly and fast.
Runway. Long. Realistically you need to reach the point where you can reimplement published papers unaided, which is a depth statement rather than a duration we can source.
Coming from ML or systems engineering with strong PyTorch? That is the realistic route — this is engineering applied to research, not a change of discipline. Machine Learning Engineer GPU / CUDA Engineer

The route
Four stations, in order. Each one is a thing you finish before the next matters.
-
Station one
Learn it free
Only the best few, deliberately. Every one of these is free to use — the pill on each card says exactly what is and isn't free.
Practical Deep Learning for Coders (fast.ai)
Free to learn · no certificate
Free, complete deep-learning course taught top-down. No certificate, and fast.ai has never pretended otherwise.
Verified 2026-07-26
PyTorch tutorials (official)
Free to learn · no certificate
The framework virtually all AI research is written in. Free and open source; docs shown for version 2.13.0.
Verified 2026-07-26
Attention Is All You Need (the transformer paper)
Free to learn · no certificate
The paper the current era is built on, free on arXiv. Reading it is not the exercise — reimplementing it is.

Station two
Attest strategically
There is no certificate for this role and buying one would be a waste. The knowledge graph lists none, and our vendor research found none. Research engineering is assessed on code: a working reimplementation of a known paper is the currency.
Nothing here is worth paying for

Station three
Prove it
A certificate says you passed a test. These say you can do the job.
A paper reimplemented from scratch
Pick a published architecture and reproduce it, matching the reported numbers as closely as you can. Document where you diverged and why — the divergences are the interesting part.
A training run at real scale
Train something across multiple GPUs and document throughput, cost, and what you changed to improve them.
An ablation someone can check
Remove one component of a model and measure what it cost you. Ablations show scientific discipline, not just engineering.

Station four
Get hired
Search these exact titles
Who hires for this. AI labs, university research groups with engineering budgets, and industrial research divisions.
A public reimplementation that matches published numbers is checkable by anyone in the field, which makes it unusually strong evidence. That is our reasoning about what is inspectable, not a hiring statistic we have verified.
On salaryWe don't publish salary estimates. Numbers copied between blogs drift from reality, and a wrong number costs you real negotiating power. When we have a verified public source, it goes here with its date.
Where this route continues
- AI Research Scientist — usually alongside publications
- AI Safety Researcher — the safety-facing continuation
- Machine Learning Engineer — sideways move
- GPU / CUDA Engineer — sideways move
Continues into research scientist roles, usually alongside publications.
