Network Engineer

Team Description:

Neuralink's Information Technology team owns the corporate environment that every engineer, scientist, and clinician depends on to do their work. Within IT, the Network function is responsible for the connectivity underneath all of it: the campus and data center networks that link our research labs, assembly lines, offices, and compute clusters, and the firewalls, wireless, and zero-trust access that keep that traffic secure. When the network is down, research stops and the line stops, so we hold a high bar for reliability, observability, and configuration managed as code.

Job Description and 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 will be responsible for the switching, routing, wireless, firewall, and NAC infrastructure that connects our research labs, assembly lines, offices, and compute clusters, and for the fiber and structured cabling that ties them together. We manage network configuration as code wherever possible and expect you to work the same way. The ideal candidate thrives in a fast-paced, high-stakes environment, responds aggressively to incidents, and has a passion for building reliable, scalable networks from the ground up. The job responsibilities will include:

• Design, deploy, maintain, and monitor campus and data center network infrastructure including switching, routing, wireless, and NAC; respond aggressively to incidents to maintain uptime
• Architect and operate high-speed data center fabrics supporting HPC and GPU clusters, including ECMP, low-latency switching, and east-west traffic design
• Deploy and manage firewalls, SD-WAN, and site-to-site connectivity; partner with the IT Security & Identity function on segmentation, 802.1x, and zero-trust network 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, and alerting in Prometheus and 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 network systems comply 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, and FTTH
• Experience with eBPF-based observability or packet analysis tooling
• Exposure to real-time systems and industrial telemetry networks
• Experience with mesh VPN and identity-aware, zero-trust network access
• Experience with centrally managed next-generation firewalls
• Industry certifications such as CCNA, CCNP, or equivalent data center certifications

Compliance & Data Privacy:

Neuralink handles sensitive patient health information and personally identifiable information (PII). All employees are expected to understand and comply with HIPAA regulations and Neuralink’s data privacy policies. This role may involve access to protected health information (PHI) and requires a demonstrated commitment to confidentiality, data security, and responsible handling of sensitive information.
