Role Overview

The Senior Machining Estimator plays a critical role in determining which opportunities TOMI pursues and how work is priced. This position requires strong knowledge of CNC machining processes, drawing interpretation skills, and the ability to translate complex engineering requirements into accurate manufacturing cost models.

You will review RFQs, analyze manufacturability, determine machining strategies, estimate cycle times, and prepare quotes for both prototype and production work.

This role works closely with the VP of Business Development, engineering, and shop leadership to ensure TOMI wins the right work at the right margins.

Responsibilities

— Review RFQ packages including drawings, models, specifications, and quality requirements

— Analyze part geometry, tolerances, GD&T, and materials to determine manufacturing approach

— Develop machining strategies and operation sequences for multi-axis CNC milling environments

— Estimate cycle times, setup time, tooling requirements, and manufacturing labor

— Evaluate fixturing strategies and potential production bottlenecks

— Estimate prototype and production machining costs

— Account for required outside processes (heat treat, coatings, plating, etc.) when applicable

— Generate quotes using Paperless Parts, Excel, and JobBOSS

— Collaborate with engineering and shop personnel to validate manufacturing assumptions

— Identify cost drivers and manufacturability considerations early in the quoting process

— Support internal discussions around pricing strategy and capacity planning

Qualifications

Required

— 5+ years of experience in CNC machining, manufacturing engineering, or machining estimation

— Strong understanding of precision CNC machining processes, particularly milling

— Ability to interpret complex engineering drawings and GD&T

— Experience estimating tight-tolerance components with complex geometries

— Strong analytical mindset and attention to detail

— Ability to manage multiple RFQs in a fast-paced manufacturing environment

Preferred

— Experience in aerospace or defense manufacturing environments

— Familiarity with Paperless Parts, JobBOSS, or similar ERP/quoting systems

— Ability to review models using Mastercam, CATIA, or similar CAD/CAM tools

— Experience estimating both prototype and production machining

— Experience working within AS9100 quality environments

Location

Santa Ana, California (on-site)

Compensation

$90,000 – $160,000 (depending on experience and performance).

This is the lowest to highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting. We may ultimately pay more or less than the posted range, and the range may be modified in the future. An employee’s pay within the salary range will be based on several factors, including, but not limited to, relevant education, qualifications, certifications, experience, technical skills, geographic location, performance, and business or organizational needs.

Why TOMI

— Work on complex aerospace and defense hardware

— Join a growing precision manufacturing company

— Be part of a highly capable machining and engineering team

— Have a direct impact on which projects the company wins and how work is priced

We are looking for a 5-Axis Setup Machinist who can independently set up and run complex parts on multi-axis CNC machines.

Role Overview

The 5-Axis Setup Machinist is responsible for setting up, proving out, and running complex CNC programs on multi-axis machining centers.

This is a hands-on, high-skill role requiring strong understanding of machining strategy, workholding, tooling, and process control. You will work on both prototype and production aerospace components, including larger structural parts, and will be expected to take ownership of setups from start to first article.

This is not a button-pushing role—this position requires experience, judgment, and attention to detail.

Responsibilities

— Set up and operate 5-axis CNC machining centers (OKK, Okuma, Kitamura, Makino, or similar)

— Interpret setup sheets, tooling lists, and CNC programs to execute efficient setups

— Install and qualify tooling, fixtures, and workholding for complex parts

— Perform first article prove-out, making necessary offsets and minor program adjustments

— Run parts to print, ensuring compliance with tight tolerances and surface finish requirements

— Work with engineering and programmers to resolve issues during setup and production

— Inspect parts using standard inspection tools (calipers, micrometers, height gauges, etc.)

— Maintain setup efficiency while ensuring quality and repeatability

— Troubleshoot machining issues including tool wear, chatter, and dimensional variation

— Maintain clean and organized work area and follow all shop procedures

Qualifications

Required

— 5+ years of CNC machining experience, including significant 5-axis setup experience
