Senior Machinist – Machinist III PAYCOR

Large Part Machining Horizontal Boring Mills Custom Fixturing CNC Programming

Location: Elk Grove CA
Job Type: FullTime
Pay Range: $4048 per hour (DOE)

PLEASE READ BEFORE APPLYING

This is not a production CNC operator role.

If your experience is primarily:

• Running existing programs
• Small vertical mills only
• Highvolume or repetitive production work

This position will not be a fit.

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

Applicants without real largepart HBM experience and CNC programming capability will be screened out.

Position Overview

We are seeking a highly skilled Senior Machinist (Machinist III) to support large complex oneoff 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.

REQUIRED EXPERIENCE (NONNEGOTIABLE)

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 jobshop environment

Resumes that do not clearly show CNC programming HBM largepart experience will be screened out.

Key Responsibilities

CNC Programming & Machining

• Program complex parts using Mastercam or similar CAM software
• Set up and operate Horizontal Boring Mills
• Machine large heavy irregular highvalue components
• Develop efficient machining strategies for oneoff and shortrun work
• Hold tight tolerances on distortionprone parts
• Perform firstarticle and inprocess 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

Crane & LargePart Handling

• Safely rig lift rotate and position large components
• Execute multistep 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

What This Role Is (And Is Not)

CNC programming machining ownership
Largescale custom oneoff work
Highskill hightrust environment
Technical influence and autonomy

Production machining
Buttonpushing or operatoronly roles
Smallpartonly CNC work

Compensation

$4048 per hour (DOE)

Pay reflects:

• Seniorlevel programming and machining skill
• Large HBM and crane responsibility
• Highrisk highvalue custom machining environment

Ideal Candidate SelfCheck

You are likely a strong fit if:

• You program your own parts not just run them
• Youve spent years on boring mills not just VMCs
• You design fixtures instead of waiting for them
• You plan complete jobs before cutting material
• You are comfortable handling very large parts safely
• You prefer complex custom machining over repetition

How to Apply (Important)

Your resume must clearly state:

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

Applications missing this information will be screened out.
