Tunnel Superintendent

With 125 years of experience, the FCC Group's Infrastructure Division is present in 25 countries, and its activities cover all areas of engineering and construction. It is a leader in the execution of transport infrastructure, as well as in residential and non-residential construction. FCC Construcción is currently the fourth-largest construction company in Spain in terms of contract volume and ranks among the top 30 in the world, according to the international magazine ENR (Engineering News-Record).

We are looking for a Tunnel Superintendent to join our FCC Team assigned to the MTA’s Second Avenue Subway Project.

This position is based in New York, NY, and requires daily presence in the office and/or on construction sites.

The MTA’s Second Avenue Subway project is a $7.7B expansion that will extend the Q Line from 96th Street into East Harlem, adding three new ADA-accessible stations at 106th, 116th, and 125th Streets. This long-awaited project will restore rapid transit access to a community underserved for decades, ease overcrowding on the Lexington Avenue line, and cut commute times—delivering a transformative impact for East Harlem residents and the city as a whole.

This position will support the $2 billion design-build contract for Phase 2, which includes two tunnels that will enable the development of two new subway stations in New York. Led by Connect Plus Partners, a joint venture between FCC Construction and Halmar International, the project brings together extensive experience in large-scale infrastructure, complex tunneling, and urban transit construction.
