Sr. IT Network Engineer (OT)

About the role

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 enabling human life on Mars. SpaceX is looking for a Senior Operational Technology (OT) Network Engineer with experience in routing, switching, and wireless in industrial network environments. This employee will be a member of the IT Network Engineering team, which is responsible for maintaining a stable, reliable, and diverse network. This network supports the design, manufacturing, and launching of rockets, spacecraft, satellites, and human spaceflight. This position will design and support industrial and OT networks for production, test, site operations, and live data center build environments. The ideal candidate will be a great communicator, able to document work in a ticketing system, excel at multi-tasking, resolve issues to prevent failures, and enjoy a fast-paced high-tech environment.

Responsibilities

• Design and implement large-scale, highly available networks, balancing routing and redundancy for production, test, and site requirements.
• Design and validate resilient, scalable multi-site OT network topologies for critical facilities.
• Evaluate, procure, and deploy network hardware: switches, firewalls, multiplexing, and SD-WAN appliances.
• Develop and contribute to network automation tooling, including configuration analysis and scalable deployment.
• Plan and coordinate network outage windows with stakeholders for software updates, hardware refreshes, and maintenance.
• Troubleshoot and resolve network issues. Publish root-cause analysis and host retrospective reviews.
• Provide networking support during launch and test campaigns, including on-call or real-time support as the networking responsible engineer.
• Tune network monitoring for operational telemetry and issue detection before impact.
• Create and update network documentation: architecture overviews, design drawings, and operational procedures.
• Work with cross-functional teams on network designs, including failure modes and redundancy.
• Perform job walks with customers, vendors, and contractors to gather requirements and create implementation plans.
• Segment industrial networks from campus and corporate networks. Maintain controls-network segmentation.
• Author system and network architecture drawings, IP/VLAN schemes, and data flow diagrams.
• Support on-site deployment, physical network cutovers, and new site commissioning.

Qualifications

Bachelor's degree in electrical engineering, computer engineering, or other STEM discipline and 5+ years of professional network engineering experience; OR 8+ years of professional network engineering experience and high school diploma or equivalency certificate in lieu of a degree.

Skills

• Industrial, utility, or operational technology network engineering experience.
• Expert understanding of the OSI model and network standards.
• Cisco, Arista, and Juniper data center-class switches.
• Wave Division Multiplexing (WDM) and fiber optics infrastructure.
• Enterprise and media protocols.
• Switch port security features, network segmentation, QoS, multicast, and redundancy protocols.
• Network monitoring tools and layer-1 testing tools.
• Scripting (Bash, PowerShell, Python) and automation frameworks (Terraform, Ansible).
• Linux and Windows system administration.
• GitOps and infrastructure as code, as a user and as a contributor.
• Layer 2 and Layer 3 design, deployment, and troubleshooting in latency-sensitive or industrial environments.
