CNC Controls & Mechatronics Service Specialist (Siemens/Fidia)

Job Description

Job Description

Is this you?

• Do you thrive on cracking tough faults in multi‑axis Milling Centers?
• Can you read a complex schematic, trace ladder logic, and zero in on a failed drive or encoder fast?
• Are you comfortable commissioning new machines on Monday and integrating automation on Tuesday?

What you’ll do

• Diagnose electrical, mechanical, hydraulic, and pneumatic problems on CNC equipment and restore performance quickly.
• Execute scheduled PMs: lube systems, alignments, sensor calibration, and accuracy checks.
• Install, level, align, and commission new CNC machines and related automation.
• Validate precision using laser interferometer and ballbar testing; verify results with precision metrology.
• Document repairs, parts consumed, and machine downtime in our ERP.

Must‑haves

• Minimum 5 years in CNC service or field service, independently handling complex onsite calls.
• Advanced command of Siemens or Fidia CNC controls and comfort with PLC ladder logic.
• Demonstrated autonomy in geometry alignment and machine leveling at customer locations.

Electrical depth and safety

• AC/DC drive systems, servo motors, encoders, and power supplies: test, diagnose, and repair.
• Expert schematic and wiring diagram literacy; trace faults to root cause.
• Troubleshoot CNC control hardware (I/O boards, HMIs, comms) on Siemens/Fidia platforms.
• Use DMMs, oscilloscopes, and megohmmeters for continuity and insulation testing.
• Operate to NFPA 70E standards and strict LOTO procedures.
• Integrate CNC with bar feeders, robotic loaders, rotary tables, and other peripherals.

Nice to have

• Experience on large 5‑axis systems (gantry or moving table).
• Familiarity with Linear Motor, Torq Motor, and Rack & Pinion motion designs.
• Strong customer service instincts and clear communication.

Travel requirements

• Frequent overnight travel for installations and complex service events.
• Short‑notice dispatches, occasional weekends, and overtime as customer needs dictate.
• Valid driver’s license with a clean record is required.
• High travel load (about 75%–100%), with regional, national, and potentially international trips.

Tools and platforms

• FMS: Siemens, Fastems
• Flexible Circuits & Interconnects: DuPont (Kapton), Amphenol
• CAD: AutoCAD, SolidWorks (2D drawings)
• Test: Multimeter, oscilloscope, megohmmeter
• Industrial Controls: Siemens; VFDs; HMIs; Servo Motors
• ERP service documentation
• Machine Platforms: 5+ axis VMCs, 5‑axis UMCs, 5+ axis HMCs
• Metrology: Calipers and micrometers

Core competencies

• Mechanical/electrical troubleshooting and repair across 120/208/240/480 V
• Industrial electrical installation and diagnostics (heavy equipment)
• Insulation resistance testing; high‑voltage systems
• Pneumatics troubleshooting; spindle maintenance and repair
• Maintenance planning; field service readiness; LOTO
• Equipment diagnostics and root‑cause analysis

Perks & support

• Company truck or service van for field work
• Daily per diem while traveling
