Lead CNC Field Service Engineer -- 5‑Axis Milling & Gantry Systems

Job Description

Job Description

Step into a day on our service team

Morning: a 5‑axis gantry throws an alarm. You arrive on site, isolate the fault with an oscilloscope and multimeter, verify encoders and servo loops, and bring the Milling Center back to peak performance. Afternoon: you level and align a newly installed moving‑table machine, confirm geometry with a laser interferometer and ballbar, and document every action in the ERP with parts usage and downtime notes. Evening: you prep for tomorrow’s trip, ready to solve the next complex challenge.

What you’ll own

• Troubleshoot and repair electrical, mechanical, hydraulic, and pneumatic issues on advanced CNC Milling Centers.
• Plan and execute preventative maintenance: lubrication, alignments, and sensor verification to extend machine life.
• Install, level, and commission new CNC machines and automation peripherals.
• Calibrate and verify accuracy using laser interferometers, ballbars, and precision metrology (calipers, micrometers).
• Create thorough service records: diagnostics performed, components replaced, and downtime tracked.

Electrical and controls depth

• Diagnose AC/DC drives, servo motors, encoders, and power supplies; validate I/O and communication interfaces.
• Read and interpret complex electrical schematics and PLC ladder logic to pinpoint root causes.
• Service CNC control hardware (Siemens or Fidia), including boards, HMIs, and fieldbus communications.
• Use digital multimeters, oscilloscopes, and megohmmeters for circuit tests, continuity, and insulation checks.
• Work to NFPA 70E and company safety protocols with rigorous Lockout/Tagout (LOTO) discipline.
• Integrate and troubleshoot automation: bar feeders, robotic loaders, rotary tables, and related interfaces.

What you bring

• 5+ years as a CNC Service or Field Service Technician, with independent field repair experience.
• Advanced mastery of CNC controls (Siemens or Fidia) and solid understanding of ladder logic.
• Proven autonomy in machine leveling, geometry alignment, and complex on‑site diagnostics.

Preferred extras

• Background with large 5‑axis systems (gantry or moving table).
• Experience with Linear Motor, Torq Motor, and Rack & Pinion motion architectures.
• Customer‑centric communication and interpersonal skills.

Travel profile

• Frequent overnight trips for installs and complex repairs; willingness to travel multiple days in a row.
• Flexibility for short‑notice dispatches, occasional weekends, and overtime to minimize customer downtime.
• Valid driver’s license with a clean record.
• High travel intensity (approximately 75%–100%), with regional, national, or international assignments as needed.

Tools, platforms, and machines you’ll touch

• Flexible Manufacturing Systems (Siemens, Fastems)
• Flexible Circuits & Interconnects (DuPont — Kapton flexible circuits, Amphenol)
• 2D Drawings (AutoCAD, SolidWorks)
• Multimeters, oscilloscopes, megohmmeters
• Industrial Controls (Siemens), VFDs, HMIs, Servo Motors
• ERP software for service documentation
• CNC Mills (5+ axis VMC), Universal Machining Centers (5‑axis UMC), Horizontal Machining Centers (5+ axis)
• Calipers and Micrometers

Core capabilities

• Mechanical and electrical troubleshooting; installation and repair across 120/208/240/480 V systems
• Industrial electrical systems; insulation resistance testing; high‑voltage safety
• Pneumatics troubleshooting; spindle maintenance & repair
• Field service readiness; equipment diagnostics; LOTO best practices

Benefits that support your work

• Company vehicle (truck or service van) for field deployments
• Daily per diem for meals and incidentals while traveling
• All travel and hotel costs covered or reimbursed
• Company‑provided cell phone and laptop
