Network Engineer
Neuralink · South San Francisco, California, United States
About this role
**About Neuralink** We are creating devices that enable a bi-directional interface with the brain—restoring movement to the paralyzed, restoring sight to the blind, and revolutionizing how humans interact with their digital world. **Team Description** Neuralink’s Information Technology team owns the corporate environment that engineers, scientists, and clinicians depend on. Within IT, the **Network** function is responsible for the connectivity underneath it all: campus and data center networks, plus the firewalls, wireless, and zero-trust access that keep traffic secure. When the network is down, research stops—so we hold a high bar for reliability, observability, and configuration managed as code. **Job Description & Responsibilities** Neuralink is looking for a **hands-on Network Engineer** to own the design, build, and operation of our campus and data center networks. You’ll be responsible for switching, routing, wireless, firewall, and NAC infrastructure connecting research labs, assembly lines, offices, and compute clusters—along with the fiber and structured cabling that ties it together. We manage network configuration as code wherever possible and expect you to work the same way. You should thrive in a fast-paced, high-stakes environment, respond aggressively to incidents, and enjoy building reliable, scalable networks from the ground up. **You will:** - Design, deploy, maintain, and monitor campus & data center network infrastructure (switching, routing, wireless, NAC); respond aggressively to incidents to maintain uptime - Architect and operate high-speed data center fabrics for HPC/GPU clusters (ECMP, low-latency switching, east-west traffic design) - Deploy and manage firewalls, SD-WAN, and site-to-site connectivity; partner with IT Security & Identity on segmentation, 802.1X, and zero-trust access - Own fiber and structured cabling design across buildings and data center spaces (including WDM, GPON, and fiber plant documentation) - Automate network configuration, provisioning, and validation using Terraform, Ansible, and scripting (Python, Bash); treat network state as versioned, reviewable code - Operate network observability (SNMP, sFlow, telemetry, alerting in Prometheus/Grafana); drive capacity planning from the data - Plan and coordinate maintenance windows, upgrades, and expansions; maintain 24/7 on-call readiness for network incidents - Ensure compliance with HIPAA, PII handling requirements, and applicable cybersecurity standards (ISO, NIST) - Author and maintain network topology diagrams, design documents, runbooks, and SOPs - Manage network hardware inventory, vendor relationships, and procurement for switches, routers, wireless, and optics **Required Qualifications** - Hands-on experience with enterprise switching, routing, and wireless platforms - Working knowledge of routing protocols and network technologies: BGP, OSPF, ECMP, TCP/IP, DNS, DHCP, SNMP, NTP, PTP, ARP, CDP, LLDP - Experience with firewalls, SD-WAN, NAC, and enterprise network security technologies - Experience designing or operating high-speed data center networks for compute or storage clusters - Familiarity with network monitoring and telemetry (Prometheus, Grafana, sFlow, or similar) - Experience automating network configuration with Terraform, Ansible, or scripting - Bachelor’s degree in a technical field **or** equivalent practical experience **Preferred Qualifications** - Familiarity with Wave Division Multiplexing, fiber optics, GPON
