Responsibilities

As a Lead Fiber Technician on SpaceXAI's traveling data center build team, you will lead crews in the installation, testing, and commissioning of high-performance fiber optic infrastructure across multiple new and expanding data center sites. You’ll bring strong leadership, technical expertise, and a safety-first mindset to fast-paced hyperscale construction projects. This role involves significant travel to support greenfield and expansion builds, ensuring reliable, high-speed network connectivity that powers SpaceXAI's AI training clusters. You will mentor technicians, drive execution excellence, and help deliver mission-critical infrastructure on aggressive timelines.
Serve as crew leader for traveling fiber teams, managing daily work assignments, resource allocation, and execution based on Fiber Span sheets, site surveys, path planning, and cross-functional coordination.
Lead and mentor a team of Fiber Technicians across multiple project sites, providing on-the-job training, technical guidance, and performance feedback.
Oversee all phases of fiber optic installation projects from planning and mobilization through execution, testing, handover, and closeout at new data center builds.
Ensure a safe, productive, high-quality, and compliant work environment in dynamic construction settings.
Develop and monitor sensor indicators; conduct timely inspections and quality checks to prevent system issues.
Troubleshoot, resolve, repair, and install complex fiber optics systems in both OSP and ISP environments.
Lead fiber splicing (fusion and mechanical), termination, labeling, and certification activities.
Examine, replace, and optimize faulty or aging fiber optic cables and infrastructure.
Organize scheduled maintenance, testing routines, and documentation during build phases.
Monitor signal strength, attenuation, and overall network performance; maintain detailed system records, as-built drawings, and designs.
Coordinate closely with superintendents, project managers, other trades (electrical, mechanical, controls), and GC teams to align with overall data center construction schedules.
