Full Job Description

Large Part Machining | Horizontal Boring Mills | Custom Fixturing | CNC Programming

Location: Elk Grove, CA
Job Type: Full‑Time
Pay Range: $40–48 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
High‑volume or repetitive production work

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.

Position Overview

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.

REQUIRED EXPERIENCE (NON‑NEGOTIABLE)

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.

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, high‑value components
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

Crane & Large‑Part Handling

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

What This Role Is (And Is Not)

✅ CNC programming + machining ownership
✅ Large‑scale, custom, one‑off work
✅ High‑skill, high‑trust environment
✅ Technical influence and autonomy

❌ Production machining
❌ Button‑pushing or operator‑only roles
❌ Small‑part‑only CNC work

Compensation

$40–48 per hour (DOE)

Pay reflects:

Senior‑level programming and machining skill
Large HBM and crane responsibility
High‑risk, high‑value custom machining environment

Ideal Candidate Self‑Check

You are likely a strong fit if:

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 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 you’ve machined
Fixturing and setup responsibility
Crane or rigging experience

Applications missing this information will be screened out.

Optional Note to Candidates

This role may be well‑suited for experienced or semi‑retired machinists who enjoy hands‑on CNC programming and large‑part machining without the pressure of production quotas.

Pay: $40.00 - $48.00 per hour

Expected hours: No less than 40.0 per week

Benefits:
