Responsibilities

Lead traveling fiber teams by managing daily work assignments, resource allocation, and execution based on Fiber Span sheets, site surveys, path planning, and cross-functional coordination.
Lead and mentor Fiber Technicians across project sites, providing on-the-job training, technical guidance, and performance feedback.
Oversee fiber optic installation projects from planning and mobilization through execution, testing, handover, and closeout at new data center builds.
Maintain a safe, productive, high-quality, and compliant work environment in construction settings.
Develop and monitor sensor indicators and conduct timely inspections and quality checks to prevent system issues.
Troubleshoot, resolve, repair, and install fiber optic systems in outside plant and inside plant environments.
Lead fiber splicing, including fusion and mechanical splicing, 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 network performance; maintain system records, as-built drawings, and designs.
Coordinate with superintendents, project managers, electrical, mechanical, and controls trades, and general contractor teams to align with data center construction schedules.
Support site mobilization and demobilization, tool and equipment management, and knowledge transfer between projects.

Desired Qualifications

Experience in Tier 3 or Tier 4 and hyperscale environments.
Experience on traveling or multi-site construction and build projects.
Hands-on knowledge of fiber optic best practices, optical time-domain reflectometer and power meter testing, structured cabling, and safety protocols.
Fiber optics and/or cable installation certification, such as FOA, BICSI, or equivalent.
Extensive experience with fusion splicing, high-density fiber deployments, and hyperscale, AI, or high-performance computing data center environments.
Technical knowledge of communication networks, fiber types such as single-mode and multimode, and associated systems.
Background in data center greenfield construction or rapid deployment projects.
Experience coordinating with general contractors and multi-trade teams in fast-paced builds.
Proficiency with project documentation, digital tools, and quality assurance processes.

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.

SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.

LEAD FIBER TECHNICIAN

As a Lead Fiber Technician on SpaceXSI'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 SpaceXSI's AI training clusters. You will mentor technicians, drive execution excellence, and help deliver mission-critical infrastructure on aggressive timelines.
