Senior Machinist – Machinist III PAYCOR

Overview

Location:

Elk Grove, CA | Full‑Time | Pay Range: $40–48 per hour (DOE)

This is not a production CNC operator role. 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.

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.

• CNC Programming & Machining
  • 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
• Custom Fixturing & Job Planning
  • 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
• Technical Leadership
  • 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

Compensation

$40–48 per hour (DOE)

Pay reflects:

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

• You program your own parts, not just run them

• You are comfortable handling very large parts safely

Your resume must clearly state :

• CNC programming experience (CAM software used)
• Horizontal boring mills operated
• Largest parts you’ve machined
• Fixturing and setup responsibility
• Crane or rigging experience
