About the Role

As a Senior Commercial Manager within WSP’s PMCM Rail Team, you will play a critical part in overseeing and driving the commercial success of complex rail projects of regional and national importance.

Your Team

You’ll join a diverse and motivated team of Project Managers, Commercial Managers and Rail specialists, all focused on delivering high‑quality commercial leadership in the Rail sector. We pride ourselves on delivering tailored solutions that shape the built environment and support the next generation of Rail infrastructure.
