Sr. Engineer - Core Network
About the role
Company Summary
Lumos is on a mission to deliver lightning-fast, 100% Fiber Optic internet to the communities that need it most. After the merger of Lumos Networks and North State in 2022, we quickly rose to become a leading fiber internet provider. And as of April 1, 2025, we’ve joined forces with T-Mobile to launch T-Fiber—a joint venture that blends Lumos’ infrastructure expertise with T-Mobile’s national reach to bring fiber to more homes than ever before.
We currently connect over 475,000 homes, businesses, and multi-family buildings across nine states in the East and Midwest. With major growth in markets like Ohio, Alabama, Florida, and Georgia—and a shared goal of reaching 12 to 15 million homes by 2030—Lumos is playing a vital role in closing the digital divide.
Our Mission and Values
At Lumos, we are driven by our commitment to a brighter tomorrow. We take pride in being the first to deliver 100% Fiber Optic Internet for families, small businesses, and communities. Guided by our purpose and startup mindset, we step up, move first, and adapt as we go. We are all servant leaders, confident in our purpose and humble enough to pay close attention to the details. We put people first and are passionate about our customers’ experience.
