Wire EDM Machinist

Valar Atomics•Hawthorne, CA

About The Position

We’re looking for a skilled Wire EDM Machinist to run precision parts on a Mitsubishi MV 2400S. This role covers the full workflow from print to part: programming, setup, cut strategy selection, process optimization, and inspection. You’ll work in a high-mix, low-volume environment where accuracy, surface finish, and repeatability are critical.

Requirements

Proven experience as a Wire EDM Machinist, including setup and operation on Mitsubishi or similar machines.
Strong ability to read and interpret prints, GD&T, and technical specifications.
Solid understanding of EDM fundamentals: burn conditions, skims, flushing, wire selection, workholding, and material behavior.
Comfortable troubleshooting process issues and making adjustments to consistently hit tolerance and finish.
Skilled with precision measuring tools and inspection best practices.
High attention to detail and commitment to producing accurate, high-quality parts.
Ability to work independently and collaborate with a team in a fast-paced shop environment.

Nice To Haves

High-mix, low-volume experience is a plus.

Responsibilities

Set up, operate, and maintain a Mitsubishi MV 2400S Wire EDM to produce high-quality, high-precision components.
Program and edit wire EDM jobs at the machine and/or using offline programming as applicable (cut conditions, skim strategies, and start hole planning).
Interpret engineering drawings, blueprints, and GD&T to ensure parts meet dimensional and geometric requirements.
Select and optimize wire type/diameter, power settings, flushing, and skim passes to hit tolerance and finish targets.
Plan and execute challenging cuts including tight tolerances, fine features, sharp internal corners, and fragile geometries.
Perform quality control inspections using micrometers, calipers, height gauges, indicators, pin gauges, optical comparator/CMM (as available).
Troubleshoot issues such as wire breaks, unstable cuts, taper/straightness variation, poor finish, and dimensional drift.
Work with engineering and production to improve fixturing, reduce cycle time, increase reliability, and prevent scrap.
Track consumables and maintain machine condition (filters, dielectric system, wire path components) according to preventative maintenance schedules.
Maintain a clean, safe work environment and follow all safety and operational standards.
Support documentation of setups and repeat jobs (fixtures, notes, inspection plans) to improve repeatability.
