## Job description

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 understand the universe and help expand humanity’s knowledge and capabilities. We work across the full Super Intelligence stack: compute (Colossus supercomputers), models (Grok), and applications (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.

## ABOUT THE ROLE:

As a Data Center Fiber Technician at SpaceXAI's data center, you’ll dive into the world of fiber optic systems, applying your core skills and eagerness to grow in a high-growth tech environment. Working onsite with passionate teams, you’ll tackle hands-on challenges to install and maintain critical network infrastructure, ensuring seamless connectivity. Expect to collaborate closely, refine your expertise, and keep our systems running smoothly to support SpaceXAI's mission of accelerating human scientific discovery through AI.

## RESPONSIBILITIES:

- Under the guidance of the Foreman Supervisor, Project Manager, and Superintendent manage all phases of data center installation projects
- Ensure a safe and productive work environment
- Develop sensor indicators and conduct timely inspections, so that a faulty fiber optic system does not destabilize its performance
- Troubleshoot, resolve, repair and install fiber optics systems, ensuring that they work properly
- Examine and replace faulty and/or old fiber optic cables
- Organize scheduled maintenance routines
- Take care of fiber splicing and rectify fiber optic problem areas
- Keep track of the signal strength of different devices
- Formulate and maintain system records and system designs

## BASIC QUALIFICATIONS:

- 3+ years of direct data center experience installing and routing optical fiber in large scale Tier 3 or 4 facilities as a commercial fiber optic technician
- High school diploma or equivalency certificate
- Position is subject to pre-employment drug and random drug and alcohol testing
- Position is subject to pre-employment and annual post employment background checks
- Physical Requirements:
- Work is often performed in tight quarters and physical dexterity is necessary to perform job functions
- Ability to lift up to 35lbs unassisted
- Comfortable working at elevated heights (up to 50 feet) with appropriate safety gear
- Comfortable working in an environment requiring exposure to noise
- Available to work evenings and weekends, as the schedule varies depending on site operational needs; flexibility is required

## PREFERRED SKILLS AND EXPERIENCE:

- Certification in fiber optics and/or cable installation
- Extensive experience in fiber splicing
- Technical knowledge of communication networks
- Knowledgeable of computers and associated electronic systems
- Knowledgeable of different fiber types
- Experience installing, certifying, and troubleshooting fiber in hyperscale data center environments
- Experience installing structured cabling
- Highly proficient using a light meter, OTDR (Optical Time Domain Reflectometer), OPMs (optical power meter), fiber certifier, loopback, and optical probes
- Able to understand different types of switches and port identifications
- Able to properly clean fiber and validate cleanliness
