Company Description

ReasonCore AI is a dynamic and innovative organization focused on advancing the field of artificial general intelligence.
We pair proprietary data-engine technology with a global network of vetted data experts to produce the high-end reasoning content that internet-scale data simply cannot supply — across scientific, financial, coding, and spatial domains.
Headquartered in the San Francisco Bay Area, ReasonCore AI is committed to fostering creativity, collaboration, and adaptability. Joining our team means contributing to impactful projects that push the boundaries of AI innovation.

The role

You will be one of the experts on the front line of our data engine: designing, authoring and reviewing reasoning content that frontier AI labs use to train their best models. This is not labeling. This is advanced LLM reasoning work — constructing multi-step problems, producing reference solutions, and helping us define what "a correct answer" looks like in your domain.

We are hiring across four reasoning verticals; please indicate your strongest domain when applying:





· Spatial reasoning (3D / 4D scenes, AV perception, robotics)

· Scientific (physics, chemistry, biology, materials science)

· Financial (markets, statements, quantitative tasks, risk modeling)

· Coding (multi-step software engineering, tool use, debugging)

What you will do

· Author original reasoning problems and reference solutions, calibrated to lab-defined difficulty bands.

· Review and rate model responses on rubric criteria; identify failure modes and edge cases.

· Contribute to private benchmarks and Eval-as-a-Service datasets shipped to frontier labs.

· Document your work clearly enough that it can train and evaluate models for years.

Whom are we looking for

· Currently enrolled (or recently graduated) students in one of the four domains above from an accredited university.

· Robust English written communication; clear, unambiguous, structured.

· Comfort working independ
