Questions

How much does Northrop Grumman pay for backend engineering roles?

The median of the 199 posted ranges is $130k a year; the middle half sits between $115k and $148k.

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.

Which level pays most?

Staff and principal roles have the highest median here: $211k a year across 19 postings.
