MasTec Communications Group jobs

The communications side is the part of MasTec that matters on a fiber board: wireless and wireline fiber engineering, building, installation, maintenance, and upgrades, reported as its own segment. The parent is an infrastructure engineering and construction company with about 36,000 employees and 810 locations as its 2025 filing counts them, in business for over 95 years counting its predecessor companies.

Everything else in the group tells you what a career here can turn into. MasTec also builds power delivery infrastructure, including transmission, distribution, and grid hardening; power generation, mostly clean energy and renewables; pipelines for natural gas, water, and carbon capture; heavy civil work such as roads, bridges, and rail; and environmental remediation. In early 2025 it moved a utility component out of the Communications segment and into Power Delivery to line the segments up with their end markets, which is the kind of reshuffle that quietly changes who a crew reports to. Most of the work runs under master service agreements, generally multi-year, rather than one-off projects, so the crews tend to stay in a region across several jobs. If you are weighing fiber contractors, that mix of long agreements and 810 locations is the practical difference from a shop that lives project to project.
