You can embrace your curiosity in a culture that celebrates new ideas and diverse perspectives. You can experience a world of opportunity and the chance to shape a career as unique as you.

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. Operating within our clients’ organisations and delivery teams, you will ensure commercial governance, financial control, and proactive risk management across multidisciplinary rail programmes. You’ll work hand‑in‑hand with your client’s Project Manager and wider teams to safeguard commercial performance, support programme delivery, and maintain the integrity of commercial processes from project initiation through to close‑out. This role is ideally suited to a mid‑career commercial professional with strong Rail sector experience who is ready to take greater ownership, lead client relationships, and operate confidently on large, fast‑paced programmes with multiple stakeholders.

At WSP, our Senior Commercial Managers thrive because they are adaptable, collaborative and highly capable of navigating complex delivery environments. You’ll work flexibly across WSP offices, client offices, and project sites to support the successful delivery of strategic Rail programmes. We are committed to supporting a positive work–life balance. You’ll be based in one of our modern, central UK offices, with hybrid working (minimum three office days per week) to help you stay connected with colleagues and clients. With WSP, you’ll have the opportunity to progress your career, deepen your Rail expertise, and shape the commercial outcomes of some of the UK’s most significant transport investments.

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.
