Questions

How much does xAI pay for backend engineering roles?

The median of the 22 posted ranges is $440k a year; the middle half sits between $346k and $440k.

Is this base salary or total compensation?

Base salary as written in the posting. Many US employers post ranges under state pay transparency laws (California, New York, Washington, Colorado and others); equity and bonus are not part of these figures.

Why posted ranges and not self-reported salaries?

A posted range is what the employer commits to for a role it has open today. It is fresher than a survey and cannot be inflated by respondents. Each posting counts once, at the midpoint of its range.
