Loop Testing Technician – Ground Equipment

The Senior Loop Testing Technician plays a critical leadership role in the commissioning and validation of instrumentation and control loops for ground equipment. This role oversees complex loop testing operations, ensures adherence to project timelines, and provides advanced troubleshooting expertise. The technician works closely with I&C engineers and project managers to guarantee the operational integrity of all control and monitoring systems used in facility, test stand, or launch operations.

Key Responsibilities:

• Lead Loop Testing Activities:
  Plan, execute, and supervise end-to-end loop checks on analog, digital, and control signals between field devices (sensors, valves, transmitters) and control systems (PLC/DCS).

• Advanced Troubleshooting:
  Identify and resolve complex instrumentation issues, including signal interference, grounding faults, scaling mismatches, and configuration errors.

• System Commissioning Support:
  Collaborate with engineering teams during system bring-up and commissioning to validate loop functionality under operational conditions.

• Mentorship & Team Leadership:
  Mentor junior and mid-level technicians, delegate tasks, review test results, and ensure consistent application of best practices and standards.

• Documentation & Reporting:
  Oversee the completion and accuracy of loop test sheets, redline drawings, and final as-built documentation. Report test metrics and status updates to project stakeholders.

• Compliance & Standards:
  Ensure loop testing activities comply with industry standards (ISA, IEC, NEC) and organizational quality procedures.

• Interface with Engineering Teams:
  Coordinate with control system engineers and I&C designers to review loop drawings, instrument specifications, and calibration procedures.

Key Focus Areas:

1. System Integrity & Reliability:
   Ensure all instrumentation loops are fully verified, documented, and capable of providing accurate real-time data under operational stress.

2. Technical Leadership:
   Serve as the field authority on loop testing practices and provide hands-on leadership during high-stakes system validations.

3. Commissioning Efficiency:
   Minimize rework and project delays by proactively identifying risks and resolving signal or configuration issues early.

4. Continuous Improvement:
   Identify gaps in loop testing processes and contribute to the development of improved testing standards and procedures.

Qualifications:

• Associate or bachelor’s degree in Instrumentation, Electrical Engineering Technology, or related field

• 5–10+ years of hands-on experience in I&C loop testing and commissioning for ground support or industrial systems

• Proficient with loop testing tools (multimeter, loop calibrator, HART/Fieldbus communicator, signal simulators)

• Advanced ability to read and interpret P&IDs, loop drawings, wiring diagrams, and instrument data sheets

• Strong understanding of control systems architecture (PLC/DCS/SCADA), sensor technology, and signal processing

• Proven ability to lead field teams and interface with multidisciplinary engineering teams

• Familiarity with safety regulations, documentation standards, and QA/QC processes
