Applied AI Scientist
Applied AI scientists live in the productive tension between research papers and product roadmaps. The work is reproducing a result from arxiv on a Tuesday, then deciding by Thursday whether it can be adapted to a problem nobody else has framed yet.
Days mix ablation studies, careful evaluation design, and conversations with engineers about what's realistic to ship. Good work here looks like an experiment that disproves your favorite hypothesis cleanly, then suggests a better one.
Students grow into this role by treating PyTorch and Hugging Face Transformers as their lab bench and learning to write up findings the way a scientist would — with assumptions, limitations, and a path for the next person to extend the work.

AI Safety Researcher
Think of this role as the loyal opposition inside an AI lab. While teammates race to make a model more capable, AI safety researchers ask what happens when it succeeds — at the wrong thing, for the wrong reasons, in the wrong hands. The work spans red-teaming prompts, designing constitutional methods that nudge models toward principled behavior, and translating findings into guardrails that product teams can actually adopt. Good work here is rigorous and humble: it admits what's still unknown rather than papering over it. Students grow into this path by pairing technical depth in PyTorch with reading widely across ethics, policy, and security. The field rewards people who can hold both at once.
AI Research
ML Researcher
What if attention worked differently? What if a smaller model, trained better, could match a much larger one? ML researchers chase questions like these for a living. The role exists to push the frontier of what models can do — through careful ablation studies, novel architectures, and the patient grind of running experiments that often disprove your favorite hypothesis. Days mix reading recent papers, sketching ideas, and writing JAX or PyTorch code that someone else will read in six months. Students grow into this path through reproducing published results before inventing their own, and learning to write up findings with intellectual honesty. The best researchers stay curious about why something worked, not just that it did.
AI Research
Research Scientist
What does a model actually learn, and can we prove it? Research scientists in AI labs spend their careers refining that question. The work alternates between long stretches of reading, careful ablation studies in PyTorch, and the rare moment when a benchmark moves and you understand why. CUDA kernels and diffusion model architectures sit in the toolkit, but the real currency is taste: knowing which experiment is worth a week of compute and which is a distraction. Students who thrive here tend to come from machine learning, physics, or pure math, and they read papers the way novelists read novels. Expect a long apprenticeship reproducing others' results before your own ideas earn a place at a top venue.
