Salary: $91,628.18 - $134,900.38/year FY 2027 schedule (last updated 2026-07-27)

New Jersey treats Geologist 4 as a competitive-class job, so the gate is an examination and the ranked list it produces rather than a direct offer.

This is the senior rung of the Geologist series, the level you reach after Geologist 3. The spec names a master's degree, but it leaves the door open to substitute experience for the degree. The FY 2027 range lands between $91,628 and $134,900, and state payroll currently lists 5 people in the title, most of them at Environmental Protection.
