Network Engineer

About Giga

Giga is building gigawatts of AI data centers to hasten a future of intelligence and abundance. We build data centers fast and at scale by combining the capabilities of an equipment supplier, engineering firm, general contractor, and real estate developer under one roof. Our team moves quickly and thinks practically. If you're ready to make an impact in an industry that matters, we're looking for people like you.

Why join Giga

• The Pace: We're building at a speed most companies talk about but never actually operate at. If you've been bored somewhere else, you won't be here.
• The Impact: Every person at Giga touches the work that matters. No layers, no waiting for approval chains. You'll see your fingerprints on what we ship.
• The Team: A team of operators defining the future of AI infrastructure. We recruit A-players from the most innovative companies in the world, and they choose Giga because the work here means more.
• The Moment: AI doesn't run without power, and that's us. Giga is the picks and shovels behind the AI revolution. This industry is about to explode, and you'll be in the room where it's already happening.

What you'll do

As the Senior Network Engineer, you will own data center networking design and implementation. We build data centers from construction through commissioning, then operate them as colocation. 
During construction you design it: the switching and routing the building runs on, structured cabling standards,
and the segmentation that separates controls traffic from everything else. Security is part of the same job, not a
separate one: firewall policy, intrusion detection, and access control between zones are yours to design and run.
After turnover you operate all of it, and you are the escalation point when something on the network breaks.
Cross-connects need to be clean and repeatable, and the controls network has to stay up. We are also building
multiple sites at once, so the standards you set on the first one determine how quickly the rest go in.

Where you'll work

This role is remote. Travel to our sites is required and will be heavy during active construction and
commissioning, when you should expect to be on site for design reviews, testing, and turnover. We have offices
in San Francisco, Long Beach, and Houston if you are near one.

Responsibilities

• Own network architecture across the portfolio: core and distribution switching, routing, out-of-band management, addressing and DNS, firewalls, and remote access, plus the standards and reference designs that make each new site a deployment rather than a redesign. • Design the physical layer inside the facility: structured cabling, pathways and cable management, cabinet and cross-connect standards, and fiber and copper plant throughout the building. • Own network security at the sites: firewall policy and rule lifecycle, intrusion detection and prevention, segmentation and access control between zones, secure remote access for staff and vendors, and network logging into our monitoring stack. • Build the colocation side of the network: customer handoffs, cross-connect provisioning, and a repeatable process for turning up tenant connectivity without one-off engineering each time. • Partner with the controls and security teams on OT networking: segmentation between IT and OT, network zones for SCADA and BMS, and reliable device-to-server paths for controls traffic. • Write the specifications, drawings, and bills of material we hand to contractors and low-voltage vendors, and review their designs and submittals so we get what we specified. Own network commissioning at each site: point-to-point testing, fiber certification, labeling, as-built drawings, and turnover documentation. • Run the network in production: monitoring and alerting, capacity planning, change control, configuration and firmware management, backups, and root cause analysis after events. • Participate in an on-call rotation and act as the escalation point for network incidents at live sites. • Write and maintain the standards, runbooks, and documentation that let the next site and the next engineer repeat this work without starting over.
