Reports to: Infrastructure Sales Director
At HSS ProService, we’ve built a smarter way for businesses to get the tools, equipment, and materials they need. Our marketplace connects customers with trusted suppliers quickly and easily, helping major projects operate faster, smarter, and more sustainably.
We’re transforming a traditional industry through technology, service, and bold thinking — and nowhere is that more visible than within our Infrastructure division, supporting some of the UK’s most significant projects including HS2 and Lower Thames Crossing.
The team you'll join
You’ll join our growing Infrastructure team — a fast-paced, commercially driven group working at the centre of some of the UK’s largest and most complex construction projects.
This is a team that works collaboratively, thinks proactively, and thrives on solving problems for customers operating in live, high-pressure environments. We move quickly, support each other, and work closely with operational, supply chain, and commercial teams to deliver exceptional results on critical infrastructure programmes.
The impact you'll have
As a Key Account Manager, you’ll take ownership of key infrastructure customer relationships across HS2, LTC, and other major projects throughout the South.
You’ll be responsible for driving account growth, delivering operational excellence, and becoming a trusted partner to customers operating on major live sites. This is a highly visible role where you’ll balance relationship management, project coordination, commercial awareness, and operational problem-solving.
