Senior Network Engineer

What You'll DoWe're building data center sites, and each one needs a Facility network that's designed right, built right and runs right after go-live. This role owns that, from the ISP handoff all the way to the BMS.You'll draw your own designs, configure your own gear, work with vendors and contractors to get it built, and support it once it's live. We move fast, so you need to be comfortable making decisions and keeping things moving.Where You'll WorkThis role is ideally based in our San Francisco, Long Beach, or Houston offices, with full-time onsite expectations outside of bi-weekly WFH Fridays.That said, we will make exceptions for truly exceptional talent if you live outside one of our hubs.

Design and draft the site-level network drawings: structured cabling, cable tray and pathways, cable specs, cabinet and cross-connect standards, and fiber and copper plant throughout the building.Network security. Own firewall policy and rules, intrusion detection and prevention, segmentation and access control between zones, secure remote access for staff and vendors, and logging into our monitoring stack.OT network.

You can write a cabling design and review someone else's.Can read and mark up construction drawings, riser diagrams and floor plans, and hold Giga's standard in design reviews with GCs and low-voltage subs.OT network security experience, including IT/OT segmentation.Experience with DCIM platforms and integrating network and infrastructure data into asset and capacity management.Strong CAD skills.
