Senior Machinist – Machinist III PAYCOR

Location:

Elk Grove, CA
Job Type: Full‑Time
Pay Range: $40–60 per hour (DOE)

PLEASE READ BEFORE APPLYING

This is not a production CNC operator role.

If your experience is primarily:

• Small vertical mills only

This position will not be a fit.

This role is for a Senior Machinist (Machinist III) with hands‑on experience programming, setting up, and machining large custom parts on Horizontal Boring Mills, including custom fixturing and overhead crane handling.

Applicants without real large‑part HBM experience and CNC programming capability will be screened out.

We are seeking a highly skilled Senior Machinist (Machinist III) to support large, complex, one‑off machining work. This position requires the ability to program, plan, fixture, set up, and machine large parts independently, with minimal supervision.

You will also serve as a technical leader, supporting less experienced machinists and contributing to tooling, cutter selection, and process decisions for future work.

Applicants must clearly demonstrate experience in most of the following areas:

• CNC programming experience (Mastercam or similar CAM software)
• Setup and operation of Horizontal Boring Mills (HBM)
• Machining large parts and large weldments
• Designing and building custom fixturing
• Safe rigging and handling of large parts using overhead cranes
• Advanced blueprint reading and GD&T interpretation
• Machining stainless steel and structural / specialty alloys
• Independently owning jobs from programming through completion
• Working with minimal supervision in a custom job‑shop environment

Resumes that do not clearly show CNC programming + HBM + large‑part experience will be screened out.

• Program complex parts using Mastercam or similar CAM software
• Set up and operate Horizontal Boring Mills
• Develop efficient machining strategies for one‑off and short‑run work
• Hold tight tolerances on distortion‑prone parts
• Perform first‑article and in‑process inspections

• Design, fabricate, and modify custom fixtures
• Plan setups considering load paths, deflection, and thermal movement
• Troubleshoot machining, alignment, vibration, and access challenges
• Support manufacturability and continuous improvement efforts
• Safely rig, lift, rotate, and position large components
• Execute multi‑step setups involving overhead crane repositioning
• Understand center of gravity, load limits, and safe handling practices

• Act as a senior technical resource on the shop floor
• Mentor Machinist I & II team members
• Recommend machining approaches and best practices
• Assist with tooling, cutter, and fixturing selection
• Provide input for ordering specialty tools and cutters for upcoming jobs

$40–60 per hour (DOE)

• Senior‑level programming and machining skill
• Large HBM and crane responsibility

• You program your own parts, not just run them
• You’ve spent years on boring mills, not just VMCs
• You design fixtures instead of waiting for them
• You are comfortable handling very large parts safely
