About the Job

Requirements

A bachelor's degree in computer science, computer engineering, or another STEM discipline and at least 3 years of professional network engineering experience, or at least 5 years of professional network engineering experience in lieu of a degree.
At least 2 years of hands-on experience in Operational Technology (OT) networking, critical facility infrastructure, industrial automation, or controls engineering.
Experience designing, deploying, supporting, and troubleshooting Layer 2 and Layer 3 networks in latency-sensitive or industrial environments.
Experience with multiple network vendors in production or lab environments.
Experience using and contributing to GitOps and Infrastructure as Code frameworks.
Ability to work in tight quarters and perform job functions requiring physical dexterity.
Availability for extended hours and/or weekends as site operational needs vary, and flexibility to accommodate that schedule.
Ability to provide 24x7 on-call support in emergencies and participate in an after-hours on-call rotation.
Willingness to travel up to 20%, including flying to other sites worldwide, and potential time at sea supporting marine systems.
Ability to lift 30 pounds.
Ability to work at heights.
Ability to drive and hold an active, valid driver's license.

Responsibilities

Design and implement highly available networks, balancing routing and redundancy technologies to meet the distinct requirements of production and launch.
Design and maintain mission data center and site networks according to company network standards, collaborating with adjacent infrastructure and enterprise teams.
Evaluate, procure, and deploy network hardware, including switches, firewalls, multiplexing, and SD-WAN appliances.
Contribute to network automation tooling by implementing configuration analysis, linting, and scalability in the deployment framework.
Plan and coordinate network outage windows with stakeholders for software updates, hardware refreshes, and general network maintenance, sometimes on weekends and evenings.
Troubleshoot and resolve network issues, publish root cause analysis documentation, and host retrospective data reviews.
Provide direct networking support during launch and test campaigns, and provide on-call or real-time networking support as the responsible engineer during operations.
Tailor network monitoring to improve operational telemetry and detect issues before operational impact.
Create and update network documentation, including architecture overviews, design drawings, and operational procedures.
Collaborate with cross-functional teams to identify and resolve potential technical issues with network designs, particularly systemic cascading failure modes and superficial redundancy.
Conduct job walks with customers, vendors, and contractors to gather network requirements and create implementation plans.
Ensure networks comply with industry and cybersecurity standards, including ITAR, ISO, and NIST, with particular attention to network segmentation and security controls.
Design and validate resilient, scalable, multi-site OT network topologies optimized for critical facilities.
Audit and enforce zero-trust firewalls to decouple facility infrastructure from the corporate DMZ.
Author system and network architecture drawings, IP/VLAN schemes, and data flow diagrams.
Support on-site system deployment, physical network cutovers, and new site commissioning.

Desired Qualifications

Strong understanding of the OSI model and network standards.
Hands-on experience with Cisco, Arista, and Juniper data center-class switches.
Experience with Wave Division Multiplexing (WDM) and fiber-optics infrastructure.
Extensive knowledge of common enterprise and media protocols.
Experience with switch port security features, network segmentation, Quality of Service (QoS), multicast, and redundancy protocols.
Familiarity with network monitoring tools and Layer 1 testing tools.
Proficiency in scripting with Bash, PowerShell, or Python, and experience with automation frameworks such as Terraform or Ansible.
Professional or laboratory Linux and Windows system administration experience.
Industry-standard certifications such as CCNA or CCNP.
Experience supporting real-time systems, industrial control networks, or OT environments in aerospace, defense, energy, oil and gas, or similar high-reliability industries.
Ability to communicate effectively with internal and external customers, vendors, and management in formal and informal situations.

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.
