Senior Machinist - Machinist III 4-Axis 3D PAYCOR

Pay: $40.00 - $60.00 per hour Job description: 4‑Axis CNC Machining | Complex 3D Work | Mastercam / CAM Programming | Renishaw Probing Location: Elk Grove, CA Job Type: Full‑Time | On‑Site Pay Range: $40.00 – $60.00 per hour (DOE) Primary Machine: Doosan NHP 8000 Horizontal Machining Center | 4‑Axis (B‑Axis Rotary) | Pallet Changer PLEASE READ BEFORE APPLYING (Important) This is not a production operator role and not a “run existing programs” position.

If your experience is primarily: CNC operation without programming responsibility 3‑axis VMC work only High‑volume or repetitive production machining This position is not a fit. This role is for a Senior Machinist (Machinist III) who can program, set up, and machine complex 3D parts on a 4‑axis horizontal machining center, and who has hands‑on experience with Renishaw probing, including creating and modifying probing routines and subroutines/macros.

Applicants without CAM programming + 4‑axis experience + probing capability will be screened out.

Position Overview

We are seeking a highly skilled 4‑Axis CNC Programmer/Machinist to support complex, high‑value machining work requiring strong process ownership, advanced setup strategy, and in‑process probing/verification. This role is centered on a Doosan NHP 8000 horizontal machining center with pallet changing and a B‑axis rotary table.

The successful candidate will own jobs end‑to‑end — CAM programming → fixturing → setup → probing → machining → inspection → optimization — in a custom, non‑production environment. REQUIRED EXPERIENCE (Non‑Negotiable) Your resume must clearly demonstrate most of the following: ✅ CNC Programming (Required) Mastercam (preferred) or comparable CAM software (NX, Fusion, Power.

Mill, etc.) Creation and optimization of 3D toolpaths for complex geometry Experience programming 4‑axis machining using B‑axis rotation Ability to post, prove out, and safely run new programs Solid understanding of work offsets, tool control, and collision avoidance ✅ 4‑Axis / Complex 3D Machining (Required) Hands‑on experience machining complex 3D parts on horizontal machining centers Effective use of 4‑axis positioning (B‑axis) to access multiple faces and reduce setups Ability to hold tight tolerances and produce high‑quality surface finishes Advanced blueprint reading and GD&T ✅ Renishaw Probing + Routine Programming (Required) Hands‑on use of Renishaw probing systems for: part pickup and alignment work offset setting and updating bore/boss location verification in‑process inspection and verification checks Ability to create and edit probing routines Experience writing or modifying probe subroutines/macros to improve repeatability and reduce setup time ✅ Workholding & Process Ownership (Required) Experience designing and building custom fixtures Comfortable owning jobs independently from programming through completion Horizontal machining experience strongly preferred Experience using pallet‑changing machines a plus If your resume does not clearly show CAM programming, 4‑axis machining, and Renishaw probing experience, please do not apply.
