Job description

The Work

Delva Tool & Machine builds precision aerospace and defense components where a half-thousandth of an inch is the difference between a part that ships and a part that doesn't. We need production operators who can run Haas CNC equipment consistently, keep parts moving, and take pride in hitting tolerance every cycle.

What You'll Own

• Run production cycles on Haas CNC mills and lathes, loading and unloading parts and materials per established work instructions.
• Within your first 90 days, become trained and fully operational on all current production parts running on your assigned equipment.
• Measure and verify parts using calipers, micrometers, and gauges at each stage, catching issues before they reach inspection.
• Monitor your machine for any irregularities, tool wear, or abnormal behavior and flag problems to your supervisor immediately.
• Deburr, clean, and prep finished parts for inspection or the next operation, following the traveler and work instructions step by step.
• Keep your work area clean, organized, and in compliance with shop safety policies at all times.

Why Delva

We hold tolerances to +/-0.0002" on aerospace and defense components, which means the work you do here actually matters. Our facility is AS9100 Rev D certified and runs two full shifts across Vertical Mills, Lathes, Swiss Lathes, and Mazak 5-axis horizontals with robotic loaders and automated pallet systems. This is not a job shop turning out one-offs; it's a disciplined production environment where precision is the baseline, not the goal.

What You Bring

Required (Machinist I):

• High School Diploma, GED, Trade/Vocational Certificate, or equivalent hands-on work experience.
• Basic comfort operating CNC equipment (mills, lathes, or similar machine tools).
• Ability to use common hand measuring tools: calipers, micrometers, and gauges.
• Attention to detail and a willingness to follow written work instructions precisely.

Required (Machinist II, if applying at the higher level):

• 3+ years of CNC machining experience.
• Ability to read and interpret engineering drawings, blueprints, and GD&T callouts.
• Experience adjusting offsets, replacing tooling, and diagnosing common machining problems (dimensional drift, surface finish, tool wear).
• High School Diploma, GED, Trade/Vocational Certificate, Associate's Degree, or equivalent work experience.

Nice to have (either level):

• Prior experience on Haas CNC equipment specifically.
• Background in aerospace, defense, or other high-tolerance manufacturing environments.
• Familiarity with AS9100 or similar quality management systems.

Pay and Benefits

$20.00-$30.00 per hour ($41,600-$62,400 per year), depending on level and experience. Delva offers medical benefits, 401(k), and paid time off. Full details provided during the interview process.
