CHEMIST 4

Code: 01555 Common Competitive Range: S28 (FY2027)

Career Family: CHEMIST

Salary: $91,628.18 - $134,900.38/year FY2027 schedule (last updated 2026-05-08)

New Jersey treats Chemist 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 Chemist series, the level you reach after Chemist 3. The spec names a bachelor's degree, but it leaves the door open to substitute experience for the degree. The FY2027 range lands between $91,628 and $134,900.

How to apply

  • Exam

    This is an application to sit an exam and be placed on an eligible list for this title, not an application for a specific job. A $35 application fee applies to Non-Public-Safety announcements issued on or after 2026-02-01. There may be no current vacancy behind it, and the list it produces may not be certified for months or years.

  • Exam

    Open to permanent employees in the competitive division who hold a qualifying lower title in the same unit. A $35 application fee applies to Non-Public-Safety announcements issued on or after 2026-02-01. Like the open competitive exam, this places you on a list; it is not itself a job offer.

Pay ladder: Chemist series

  1. Chemist 1 — $66,592 – $97,354
  2. Chemist 2 — $69,668 – $101,951
  3. Chemist 3 — $87,507 – $128,719
  4. Chemist 4 — $91,628 – $134,900 (this title)

Its top salary lands around the 81st percentile of all NJ civil service titles that publish a range.

Rungs are ordered by FY2027 pay. NJ level numbers are not always sequential, so ordering follows salary rather than the title number.
