Delva Tool & Machine•Cinnaminson Township, NJ

1d•$30 - $43•Onsite

About The Position

Delva Tool & Machine is an AS9100 Rev D certified precision shop in Cinnaminson, NJ, producing aerospace and defense components. We hold tolerances to +/-0.0002" across aluminum, titanium, stainless, and tool steels. Our floor runs two shifts on Vertical Mills, Lathes, Swiss Lathes, and Mazak 5-axis horizontals with robotic loaders and automated pallet systems. This is not a commodity job shop. The work is complex, the standards are high, and the mission is real.

Requirements

5+ years of hands-on CNC machining experience, including multi-axis or 5-axis equipment.
Demonstrated ability to set up and adjust programs on CNC machining centers without hand-holding.
Experience with fixture setup and part prove-out, including FAI processes.
Ability to read and interpret engineering drawings, GD&T; callouts, and job routers.
Working knowledge of feeds, speeds, and tooling selection for aluminum and at least one exotic alloy (titanium, stainless, tool steel).
High School Diploma or GED, Trade/Vocational Certificate, Associate's Degree, or equivalent work experience.
Authorization to work on ITAR-controlled aerospace and defense components.

Nice To Haves

Direct experience on Mazak 5-axis horizontal machining centers and/or Palletech automated pallet systems.
Familiarity with AS9100 quality standards and participation in shop-floor audits.
Prior lead or mentor experience on a machine shop floor.

Responsibilities

Get up to speed on the Mazak 5-axis horizontal machining centers and the Palletech robotic pallet system within your first 90 days, becoming the go-to resource on the floor for both.
Lead setup, adjust programs, and operate complex multi-axis CNC equipment; validate new programs through first runs and first-article inspections.
Serve as the primary point of contact for operators' day-to-day questions on setup, tooling, job routing, and troubleshooting; mentor Machinist I and II team members and help keep work moving efficiently on shift.
When no Supervisor or Manager is on shift, act as the floor's first point of contact for safety incidents and personnel concerns: ensure immediate safety steps are taken, document factual observations, and contact on-call leadership or HR right away. All investigation and disciplinary decisions stay with leadership.
Partner with Engineering and CNC programmers to reduce scrap, hold tight tolerances, and recommend design-for-manufacturing improvements; contribute to continuous improvement, lean, and 5S initiatives.
