Job summary

Delva in New Jersey is seeking skilled CNC machinists to operate Vertical Mills, Lathes, Swiss Lathes, and Mazak 5-axis horizontals. The role requires reading prints, performing in-process inspections, and documenting results with calipers, micrometers, and bore gauges.

At Level II, troubleshoot chatter and dimensional drift, maintain tolerances within +/-.0005", and mentor Level I operators. Pay ranges from $20–$30/hr, with full medical/dental/vision, 401(k), and PTO benefits.

Qualifications

• Operate CNC machine tools safely and follow traveler instructions.
• Read prints and traveler work instructions; perform in-process inspection with calipers, micrometers, bore gauges.
• Interpret GD&T and set up multi-axis jobs; troubleshoot dimensional issues.

Responsibilities

• Operate assigned CNC machines safely and independently.
• Read prints and traveler instructions; perform in-process inspection and log results.
• Identify tool wear early and flag issues to avoid out-of-tolerance conditions.
• Troubleshoot chatter, tool life drops, and dimensional drift; maintain tight tolerances.
• Mentor Level I machinists on the machine.

Job description

• Operate assigned CNC machines (Vertical Mills, Lathes, Swiss Lathes, Mazak 5-axis horizontals) safely and independently, contributing clean, documented spindle hours every shift
• Read prints, router sheets, and traveler work instructions accurately; perform in-process inspection using calipers, micrometers, and bore gauges; log results and downtime codes correctly
• At Level I: recognize tool wear signs and flag them before failure; escape any out-of-tolerance condition immediately and correctly, every time
• At Level II: independently troubleshoot chatter, tool life drops, and dimensional drift using a logical sequence; hold tolerances in the +/-.0005" range while accounting for thermal drift and machine-specific behavior
• Catch potential nonconformances before they become MRB events -- zero containment events from operator error is the baseline, not a stretch goal
• At Level II: actively mentor a Level I machinist on your machine

What You Will Own

• Operate assigned CNC machines (Vertical Mills, Lathes, Swiss Lathes, Mazak 5-axis horizontals) safely and independently, contributing clean, documented spindle hours every shift
• Read prints, router sheets, and traveler work instructions accurately; perform in-process inspection using calipers, micrometers, and bore gauges; log results and downtime codes correctly

• Catch potential nonconformances before they become MRB events -- zero containment events from operator error is the baseline, not a stretch goal
• At Level II: actively mentor a Level I machinist on your machine

What You Bring

Required (Level I):

• High School Diploma, GED, Trade/Vocational Certificate, or equivalent work experience
• Ability to operate CNC machine tools safely and follow traveler work instructions
• Basic measurement skills: calipers, micrometers, gauges
• Attention to detail and willingness to ask when something does not look right

Required (Level II):

• 3+ years of relevant CNC machining experience
• High School Diploma, GED, Trade/Vocational Certificate, Associate's Degree, or equivalent
• Proven ability to interpret GD&T, set up 5-axis or multi-axis jobs independently, and troubleshoot dimensional issues without guesswork
• Demonstrated track record of zero MRB events from operator error

Nice to Have (either level):

• Experience on Mazak 5-axis horizontals or DMU-style machines
• Eurotech lathe experience (active plus -- we are expanding those lines)
• Background in aerospace or defense manufacturing; familiarity with AS9100 quality systems
• Comfort with rotary/tilt axis offset strategy and bonus tolerance calculation

Pay and Benefits

$20.00 - $30.00/hr ($41,600 - $62,400/yr), based on experience and level. We offer medical, dental, and vision coverage, 401(k) with company match, and paid time off. Delva runs two shifts -- let us know your preference when you apply.
