Network Engineer

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.

ABOUT THE ROLE:

Join the High Power Engineering team supporting SpaceXSI to design, build, operate, and maintain electrical infrastructure for AI training campuses. As a Network Engineer on the Battery Storage team, you will work with a small on-site team to scale high-capacity power systems on a schedule set by compute demand. The position is based in Memphis, TN, with potential travel to other sites.

RESPONSIBILITIES:

• Own the operational technology network the storage fleet runs on: packs, inverters, medium-voltage collection, and the plant controller must talk deterministically, redundantly, and securely.
• Own site network architecture: topology, redundancy, switch selection and configuration, VLAN and subnet design, and IP addressing across the fleet.
• Own the fiber and copper physical plant: single-mode and multimode runs, splice plans, patch panel layout, labeling, OTDR acceptance testing, and pathway coordination.
• Own industrial protocol integration across Modbus TCP, DNP3, and IEC 61850 including GOOSE, plus mapping between pack controllers, PCS, plant controller, and EMS.
• Own precision time distribution using PTP per IEEE 1588 and IRIG-B for sequence-of-events and disturbance analysis.
• Own OT cybersecurity for the storage plant: segmentation per IEC 62443, firewall rules, remote access, patch and firmware management, and applicable NERC CIP evidence.
• Specify and commission industrial switches, media converters, gateways, protocol converters, terminal servers, and time sources; own configuration backup and change management.
• Support commissioning with network validation, latency and packet-loss testing, failover testing, and pack-level communications troubleshooting.

BASIC QUALIFICATIONS:

• Bachelor's degree in electrical engineering, computer engineering, computer science, or a related technical discipline, or 6+ years of relevant experience in lieu of a degree.
