Key details
Why this role is notable
A company that builds its own fiber network, tying a Colossus AI supercluster to its own ground infrastructure, is vertically integrating the physical plumbing of AI compute rather than leasing it, a sign of a bet that the bottleneck to frontier AI is physical build-out, not just chips or models.
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 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.
CONSTRUCTION MANAGER, FIBER
Most construction managers inherit a schedule someone else built and a set of contractors someone else hired. This one does not.
SpaceX builds its own launch sites, factories, test stands, and AI superclusters — and it plans to keep building. The rockets, the chips, and the missions only matter if the ground under them is real. Construction is how that ground gets built, to a standard the company can actually use. The work does not dry up between jobs. There is a next site, and one after that.
You are the senior construction lead for the fiber scope. You own the site relationships, the vendors, and the outcome. You report to central construction leadership, and that line can shift as the project evolves. You are on the job, walking the work, and clearing what is in the way.
Scope includes, but not limited to fiber optic backbone and horizontal cabling, pathways, splicing, testing, certification, and handover documentation for the data center.
Right now the job is the data center in Memphis, Tennessee. Later work can move to other U.S. construction sites.
RESPONSIBILITIES:
- Act as the senior construction representative for the Memphis data center fiber scope, managing relationships with contractors, partners, and internal stakeholders
- Oversee fiber execution from pre-construction and site development through testing, certification, and handover
- Coordinate multiple vendors so field and technical teams stay aligned on fiber backbone, horizontal cabling, pathways, splicing, and testing
- Identify and mitigate risks to quality, safety, system integrity, and operational readiness
- Drive progress on the fiber scope and resolve roadblocks so the schedule holds
- Align the fiber schedule with SpaceXSI's infrastructure goals through cross-functional collaboration
- Partner with teams on commissioning and close issues as they come up
- Deliver regular updates with clear KPIs and dashboards for internal and external stakeholders
- Hold the work to the technical and quality standards in the base design
- Perform quantity take-offs and field verifications to track progress and support reporting
- Manage change orders, cut unnecessary changes, and control cost
- Lead site safety around fiber installation, splicing, testing, and work at heights
- Support cross-functional partners as the project requires
BASIC QUALIFICATIONS:
- High school diploma or equivalency certificate
- 5+ years leading construction teams, including supervision of superintendents and foreman
PREFERRED SKILLS AND EXPERIENCE:
- Experience managing large-scale data center or mission-critical construction projects
- Certification in fiber optics and/or cable installation (FOA, BICSI, or equivalent)
- Advanced expertise in fiber splicing, OTDR testing, and certification procedures
- Deep technical knowledge of hyperscale data center networking, structured cabling, and fiber infrastructure
- Experience in AI/HPC data centers or other mission-critical facilities
- Highly proficient using a light meter, OTDR (Optical Time Domain Reflectometer), OPMs (optical power meter), fiber certifier, loopback, and optical probes
- Knowledge of different fiber types, proper cleaning/validation techniques, switches, and port identifications
- Proficiency with computers, fiber management software, and electronic testing systems
- Excellent problem-solving, communication, and organizational skills
- Deep expertise in construction management, commissioning, and site operations
- Proven ability to lead on-site with authority and build trust with vendors, partners, and technical teams
- Experience managing large programs with multiple vendors and dynamic priorities
- Strong communication skills across disciplines, from field updates to technical escalations
- Thrives in solving complex, real-time problems with adaptability and composure
- Previous experience in data center construction or highly technical facilities
- Familiarity with local Memphis building codes and regulations
- Strong problem-solving skills and ability to handle complex construction challenges
ADDITIONAL REQUIREMENTS:
- 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
- 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
- Ability to lift at least 25 lbs
- Must be willing to travel as needed
- This is a full-time, onsite role based in Memphis, Tennessee, with relocation required depending on additional construction locations within the US
