Job summary

Iron Systems, Inc. is seeking an experienced Senior Fiber Optic Splicer to support break/fix, remediation and restoration in a hyperscale data center setting. You will own defects from review to repair, documenting results and closing tickets.

The role demands hands-on expertise with single-fiber fusion splicing, ribbon/mass splicing, SC/MTP/MPO and MMC connectivity, OTDR interpretation and rigorous safety practices in energized environments.

Qualifications

• Demonstrated professional experience performing fiber fusion splicing in data center, colocation, enterprise or mission-critical environments.
• Recent hands-on experience working with live/in-service fiber infrastructure.
• Production-level proficiency in single-fiber fusion splicing, ribbon or mass fusion splicing, ribboning loose-tube fiber, SC terminations and patching, MTP/MPO connectivity, MMC high-density connectivity.

Responsibilities

• Perform fusion splicing of single-mode fibers using repeatable fiber preparation, cleaving and splicing procedures.
• Execute 12-fiber ribbon and mass fusion splicing, including ribboning fibers from loose-tube cable.
• Work with SC, MTP/MPO and MMC fiber connectivity in high-density data center environments.
• Install and repair splice-on connectors, pigtails, fan-outs and related fiber assemblies.
• Diagnose and repair defects identified through audits, inspections, testing or trouble tickets.
• Interpret fiber drawings, cable schedules, port assignments, splice plans and methods of procedure.

Job description

Position Summary

We are seeking experienced Senior Fiber Optic Splicers to support fiber break/fix, remediation, testing and restoration activities within an active hyperscale data center environment.

This is a production-level position for technicians who can independently diagnose and resolve fiber defects in both live/in-service and non-live fiber environments. The technician will be expected to own assigned defects from initial ticket review through repair, testing, documentation and closure.

Candidates must have recent, hands-on experience with single-fiber fusion splicing, ribbon/mass fusion splicing, SC connectivity, MTP/MPO systems and MMC high-density fiber connectivity. This is not a learn-on-the-job position, and routine technical issues should be resolved without requiring escalation back to the client.

Key Responsibilities

• Perform single-mode, single-fiber fusion splicing using repeatable fiber preparation, cleaving and splicing procedures.
• Perform 12-fiber ribbon and mass fusion splicing, including ribboning fibers from loose-tube cable.
• Work with SC, MTP/MPO and MMC fiber connectivity in high-density data center environments.
• Install and repair splice-on connectors, pigtails, fan-outs and related fiber assemblies.
• Diagnose and repair defects identified through audits, inspections, testing or trouble tickets.
• Interpret fiber drawings, cable schedules, port assignments, splice plans and methods of procedure.
• Understand MTP/MPO polarity methods, including Methods A, B and C.
• Verify MTP/MPO key orientation, pinned versus non-pinned configurations, gender and trunk/harness/cassette architecture.
• Perform OTDR testing and interpret traces to identify events, excessive loss, reflections, breaks and fault locations.
• Conduct insertion-loss testing using optical light sources and power meters.
• Verify results against applicable loss budgets and project acceptance requirements.
• Inspect and clean SC, MPO and other fiber end faces using appropriate inspection probes and cleaning tools.
• Apply end-face pass/fail standards consistent with project requirements and IEC 61300-3-35.
• Follow live-environment safety procedures and never inspect an energized fiber directly.
• Work strictly according to the approved ticket and method of procedure.
• Avoid disconnecting, moving or disturbing fiber components that are not included in the assigned scope.
• Document repairs, test results, photographs and supporting evidence before closing tickets.
• Provide required morning, progress and end-of-day status updates.
• Maintain splicing machines, cleavers, testing equipment and inspection tools in proper working condition.
• Follow site safety requirements, including ladder, fall-protection, access-control and tool-control procedures.

Required Qualifications

• Demonstrated professional experience performing fiber fusion splicing in data center, colocation, enterprise or mission-critical environments.
• Recent hands-on experience working with live/in-service fiber infrastructure.
• Production-level proficiency in:
• Single-fiber fusion splicing
• Ribbon or mass fusion splicing
• Ribboning loose-tube fiber
• SC terminations and patching
• MTP/MPO connectivity
• MMC high-density connectivity
• Ability to independently diagnose, repair, test and close fiber defects.
• Hands-on experience operating core-alignment fusion splicers such as:
• Fujikura 70S/90S series
• Sumitomo Type-72/Q-series
• Comparable professional fusion-splicing equipment
• Proficiency with OTDRs, optical power meters, light sources and fiber inspection microscopes.
• Ability to interpret OTDR traces rather than only operate the test equipment.
• Understanding of insertion loss, loss budgets, splice-loss thresholds, reflectance and fiber cleanliness.
• Ability to read fiber drawings, port maps, cable schedules and technical procedures.
• Strong documentation and ticket-closure discipline.
• Ability to work independently without routine client escalation.
• Comfortable working in a safety-controlled, construction-oriented data center environment.

Experience Guideline

Three or more years of directly relevant fiber-splicing experience is preferred.

However, demonstrated capability with live data-center fiber, ribbon splicing, MPO/MMC and OTDR interpretation should carry more weight than total years of experience.

Preferred Qualifications

• FOA Certified Fiber Optic Technician — CFOT
• FOA Certified Fiber Optic Specialist in Splicing — CFOS/S
• BICSI Installer or Technician certification
• OSHA 10 or OSHA 30
• Previous hyperscale data center experience
• Previous experience on Turner-managed construction sites
• Experience supporting fiber audits, remediation or live-network restoration
• Ownership of professional hand tools, fiber preparation tools or inspection equipment
