NDT Jobs & Salaries in Greenville, TX
The NDT job market in Greenville is shaped directly by its industrial base — Defense aerospace MRO, ISR aircraft modifications, Avionics / electronics manufacturing. Major employers and asset owners in the area include L3Harris Greenville (Mission Systems), Majors Field (Greenville), all of which run continuous inspection programs and rotate inspection contractors against multi-year MSAs. Code authorities most often cited in local procurement specifications are FAA Part 145, NAS 410, MIL-STD-2154, so any inspector hunting work in Greenville should expect those references in interviews and pre-qualification packages. Wages track close to the national median for inspectors, with overtime making up the variable component. A recurring local theme: "L3Harris Greenville ISR work runs classified scopes — every NDT inspector cert and every instrument cal has to be audit-defensible without leaking program-sensitive data." BLS-anchored Level II wages in Greenville run around $66,000/yr; Level III with API endorsements layers on to roughly $100,000/yr — the gap between the two is the single biggest reason local inspectors pursue Level III. Jurisdictional layer matters here: FAA Part 145 and NAS 410 apply on top of the federal/national codes, and missing the local-authority reference on a procedure submission is a common rejection reason for first-time-into-Greenville contractors. One angle that differentiates Greenville from peer markets: L3Harris ISR work runs classified scopes; cert and cal records must be audit-defensible without leaking program data. Turnaround calendar: Spring TARs (Apr-May); Autumn TARs (Sep-Oct) — the inspection workforce flexes hard against this rhythm and overtime stacks during those windows.
