Job description
We’re partnering with a frontier AI startup
We’re working with an early-stage AI company that’s redefining how models learn to understand subjective quality , from writing tone and design aesthetics to emotional resonance and creative expression.
They’re collaborating with leading AI labs and building new methods that help models reason about creativity, taste, and quality. The founding team is small, highly technical, and deeply curious—building at the intersection of research, product, and creativity .
The Role
As a Machine Learning Research Engineer , you’ll own end-to-end research cycles—designing, running, and analyzing post‑training experiments that help models evaluate style and subjective quality. You’ll collaborate directly with AI labs and creative experts, and have the opportunity to publish your work.
What You’ll Do
Train reward models, classifiers, and verifiers across creative domains (writing, design, visual style)
Develop benchmarks and evaluation methods for subjective tasks
Run post‑training (RLHF/DPO) experiments on open‑source and proprietary models
Collaborate with AI labs and creative experts on pilots and research projects
Publish findings through blogs and whitepapers
What We’re Looking For
2–6+ years in post‑training, ML research, or ML engineering
Strong experience with Python, PyTorch, LLMs , and multimodal models
Proven ability to run fast, iterative experiments from data to evaluation
Curiosity for subjective AI —creativity, tone, and aesthetics
Low‑ego, collaborative mindset; thrives in a small, in‑person environment
Bonus
Experience working with post‑training data or data vendors (Scale, Labelbox, Snorkel, etc.)
Personal interest in creative fields (design, art, writing, or similar)
Why Join
Build at the edge of AI and creativity
Collaborate with frontier research labs
Work closely with an inspiring founding team in Jackson Square, San Francisco
Competitive salary and meaningful early‑stage equity
Compensation: $200K–$350K + 0.25–1.5% equity
Interview Process:
We’re proud to partner with a founder who values creativity, collaboration, and curiosity above ego.
