What the posting says

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.

NETWORK CONNECTIVITY ENGINEER, FIBER OPTIC LAYOUT

The Data Center Engineering team designs training and inference compute clusters from first principles, pushing thermal, electrical, and optical systems to the limit of physics. We operate as a highly cross disciplinary team comprised of mechanical, electrical, optical, and software engineers, all working to maximize the efficiency, reliability, and deployment speed of terrestrial compute to serve rapidly scaling demand.

As a Network Connectivity Engineer, you will design, deploy, and qualify large scale fiber optic networks for hundreds of thousands of coherently connected GPUs. You’ll architect systems for maximum bandwidth and minimum latency, collaborating with optical, mechanical, and software engineers to translate your designs into the largest coherent computing networks in the world.

RESPONSIBILITIES:

Design and plan scalable, future-proof data center connectivity for clusters of hundreds of thousands of GPUs, including structured cabling plants that support evolving architectures and speeds beyond 800G

Procure fiber, copper, and other connectivity materials for new builds, expansions, and technology refreshes

Provide project management and construction oversight for connectivity scope on new data center builds and expansions

Plan and implement network upgrades and overhauls for technology refreshes in live data center environments

Develop Methods of Procedure (MOPs) and Standard Operating Procedures (SOPs) for connectivity deployments in live environments

Audit existing and new connectivity installations and hold vendors accountable for troubleshooting and repairs prior to network deployment turnover

Develop and maintain as-built documentation for all data center connectivity

Release and troubleshoot ISP circuits across multiple regions; interface with data center providers to drive circuit and cross-connect deployments

Collaborate with capacity planning, network engineering, hardware reliability, and construction teams on cluster design and delivery

Apply knowledge of applicable building codes and industry standards to connectivity design and installation

BASIC QUALIFICATIONS:

Bachelor’s degree in electrical engineering, mechanical engineering, computer science, or a technical discipline; OR 8+ years of practical experience

5+ years of experience working in and designing data center connectivity

Experience with multimode fiber, singlemode fiber, copper, and other low-voltage telecommunication systems

Experience with structured cabling and both active and passive cabling elements

PREFERRED SKILLS AND EXPERIENCE:

RCDD (Registered Communications Distribution Designer) certification

Experience performing budget loss, insertion loss, and return loss calculations for structured cable systems

Experience deploying network elements such as routing switches, aggregation switches, optical transceivers, and DWDM

Ability to interpret fiber test results

Experience with network connectivity testing (singlemode duplex, multimode duplex, MPO8, MPO12, MPO16, AOC, DAC, and copper) and troubleshooting using OTDR, light meters, VFLs, loopbacks, and BERT across vendors

Experience building and designing scalable fiber and connectivity plants for large-scale data centers across Ethernet, InfiniBand, and RoCE networks

Experience designing and deploying connectivity for high-speed / high-bandwidth HPC and ML applications

Experience troubleshooting optical transceivers, network switches, fiber, and other Layer 1 hardware

Knowledge of basic programming languages such as Python and SQL

Experience deploying monitoring and alerting systems for environmental, mechanical, and electrical data center systems

Ability to manage multiple projects across different time zones simultaneously

Knowledge of relevant building codes and industry cabling standards (TIA, BICSI, NEC)

ADDITIONAL REQUIREMENTS:

Physical ability to perform hands-on work in data center environments, including heat, cold, and tight quarters

Ability to work extended hours and weekends as needed to support deployments and cutovers

Ability to travel approximately 40% as required by project needs

Valid driver’s license

Ability to lift up to 25 lbs unassisted
