When should I hire a fractional data scientist?

When you need senior judgment on experiments and prototypes a few days a month, while delivery sits with engineers or a contractor.

Fractional data scientist vs fractional AI / ML engineer?

Data scientists lean toward experiment design and prototypes. AI / ML engineers lean toward serving, evaluation harnesses and production paths. Name the outcome.

How do I hire a fractional data scientist on carbon.talent?

Post the role free as fractional, set days and overlap, review vetted profiles, then agree the rate on the platform.

What belongs in the brief?

The decisions or products the science supports, data access, evaluation standards and what success looks like within the days you buy.
