What You'll Do:
We are building a global optical backbone designed to support infrastructure at massive scale. We are looking for experienced Optical Network Engineers to help design, build, operate, and evolve the optical network that underpins our global IP backbone.
This is a senior engineering role for engineers with deep, hands-on experience designing and operating production optical networks. You will work across the complete optical lifecycle, from dark fiber and photonic engineering through DWDM system design, deployment, capacity expansion, automation, monitoring, and production operations.
You will work closely with IP Backbone Engineering and Network Architecture to ensure that the optical and IP layers are designed together to provide predictable capacity, physical diversity, failure isolation, and resiliency.
We are specifically looking for engineers who understand the underlying optical network, not just how to configure individual platforms.
About the role:
You will help design, build, and operate our global optical backbone.

Who You Are:
This is a senior-level position. Candidates should have significant hands-on experience designing, deploying, and operating large-scale production optical networks.

What Success Looks Like
Successful engineers on this team will be able to independently take ownership of complex optical engineering problems. That might mean designing a new long-haul dark-fiber route, determining amplification and regeneration requirements, troubleshooting an unexpected Q-margin degradation, analyzing an OTDR trace after a fiber event, commissioning a new DWDM system, automating wavelength deployment, or working with IP Backbone Engineering to determine whether a proposed network design actually provides physical diversity.
Most importantly, you will help us build an optical backbone that can continue scaling while remaining understandable, observable, resilient, and operationally manageable.
Wondering if you're a good fit?
We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams – even if you aren't a 100% skill or experience match.
