Job Description - Transmission Project Manager (Onshore Infrastructure)

*Please Note: During these unprecedented times during the covid-19 pandemic, we are still able to recruit, hold interviews and complete any onboarding remotely. Our clients understand that processes much change and so for this position all interviews, decision and job offers will eb made remotely.*

ERSG USA are currently recruiting for a Project Manager with significant experience in transmission activities to join a world leading offshore wind company with offices across the United States and Europe.

The Project Manager for Transmission is a senior role of our clients technical and management team and will take full responsibility for managing the delivery of onshore transmission infrastructure including onshore cabling activities, landfall and the substation. This role is considered to be a critical position in terms of team interface, with strong relationships needed to be built with grid connection teams (and management), as well as the permitting team to ensure all parties are on the same page.

If we had to describe the most important responsibility for the Project Manager position, we would say it would be to competently and confidently manage a highly visible, complex, ever-changing electrical transmission project that has a high number of stakeholders, as efficiently as possible within budget and schedule.

The Project Manager will work closely with personnel throughout this major US offshore wind project to permit, design, site and construct all transmission-related elements of the project. Primary duties include overall responsibility for management of all phases and aspects of the onshore transmission project including managing the development and process for assessing the technical feasibility of the transmission circuit route options identified by the Development Team (securing land, permitting, proper siting…), managing the development and evaluation of documents for engineering, design, construction and procurement of material and support systems. The Onshore Transmission Infrastructure PM will also manage third party contractors supporting the day to day work.

As the project matures and further projects are awarded, we fully expect this position to evolve, with the Project Manager promoting themselves into more of a Package Manager position - so the immediate room for growth is already there.

This role will be based at Mayflower's office located in Boston. Should expect domestic and international travel to meet and work with stakeholders as well as occasional visits to the corporate offices of our client, whether in the UAS or Europe/
