CNC MACHINIST II (B Shift)

LISI•Garden Grove, CA

1d•$24 - $30

About The Position

The CNC Machinist II is an intermediate-level machinist responsible for independently operating CNC machines, performing basic setups, adjusting and changing tooling without supervision, troubleshooting routine machine and process issues, and supporting the training of new hires. The role requires technical judgment, ownership of assigned equipment, and proactive communication to support safe, efficient, high-quality production. The machinist operates equipment according to programs, work instructions, and safety procedures; selects materials and tooling; makes tooling and offset adjustments; and addresses routine machining issues within the role’s scope. Complex setup, programming, tooling, or quality issues are escalated to a CNC Machinist III, CNC Machinist Lead, or Supervisor. The role also communicates equipment and job status through pass-downs and problem-solving meetings, assists with work organization and continuous improvement, supports new-hire training, and maintains a clean, organized, safe work area. This position is based in a manufacturing machine shop. Work involves exposure to machine noise, metal chips, coolants, oils, fumes, mists, and temperature variations. Required personal protective equipment includes safety glasses, steel-toe footwear, and hearing protection. Physical demands include standing and walking throughout the shift, lifting and moving up to 30 pounds, repetitive hand and wrist motions, and bending, reaching, pushing, pulling, grasping, and loading parts into machines.

Requirements

3–4 years of CNC machining experience in a manufacturing environment, or an equivalent combination of training and experience.
Ability to perform basic CNC machine setups independently.
Ability to select tooling and change all tooling without supervision.
Ability to troubleshoot routine machining, tooling, and process issues.
Ability to read and interpret blueprints and basic GD&T.
Experience using precision measuring equipment.
Strong communication skills for pass-downs and problem-solving.
Experience supporting or training less-experienced machinists.
Follow safety rules, job safety analyses, and PPE requirements; stop work and escalate concerns when safety or quality risks are identified.
Complete inspections and documentation accurately and demonstrate reliable attendance.
Work collaboratively with supervisors, engineers, and planners and support teamwork and continuous improvement.

Responsibilities

Operate CNC machines in accordance with established programs, work instructions, and safety procedures.
Perform basic CNC machine setups, including tooling changes, offsets, and fixture adjustments.
Select proper materials, tool holders, and tooling in accordance with work instructions and engineering requirements.
Change tooling independently and without supervision; adjust tooling and offsets to maintain dimensional accuracy and part quality.
Troubleshoot routine machine, tooling, and dimensional issues; take appropriate corrective action within scope and escalate complex issues.
Use pass-down sheets when face-to-face shift changeover is not feasible and participate in face-to-face problem-solving meetings to communicate tooling, maintenance, equipment, machine performance, setup, and job status.
Use shop-floor systems for production tracking, quality documentation, and communication.
Assist supervisors, mechanical engineers, and planners with work organization and continuous improvement, including reducing setup time, cycle time, and machine downtime.
Implement and suggest waste-elimination initiatives, including recycling opportunities and reductions in production-related waste.
Train and support new hires on machine operation, tooling changes, inspection methods, and shop procedures.
Maintain a clean, organized, and safe work area in accordance with 5S standards.
Comply with company safety, quality, and production policies and perform other related duties as assigned.
Participate in developing and promoting the HSE culture, correcting or reporting risks and malfunctions, implementing preventive actions, and participating in requested risk, incident, or HSE working-group analyses.
Follow health, safety, and environmental instructions and rules; understand relevant workplace risks, environmental impacts, and site HSE policy and objectives; and propose improvements to working conditions and environmental impact.
