Visa sponsorship available
A stealth AI startup is building technology that teaches models what
great
feels like — across writing, design, and creative expression.
They're hiring a
Machine Learning Research Engineer
to design and run experiments that shape how models learn taste, tone, and quality. You'll focus on post-training, reward modeling, and multimodal research, collaborating with creative experts and AI labs on frontier model behavior.
What you'll do
- Run
post-training and fine-tuning
experiments (RLHF, DPO, SFT). - Develop
benchmarks and evaluations
for subjective model outputs. - Train
reward models, classifiers, and verifiers
for tone and style. - Prototype and test
multimodal architectures
(text, vision, design). - Work closely with researchers, engineers, and creative collaborators.
You might be a fit if
- 2+ years in
ML research or engineering
, especially post-training or alignment. - Hands-on with
LLMs or multimodal models
(text + image). - Strong in
Python, PyTorch
, and experimental research cycles. - Experience at a
startup or small research team
. - Creative, curious, and interested in how AI learns taste and aesthetics.
If you want to help define how AI understands creativity, emotion, and style — this is the kind of research role that sets the standard.
