THE TEAM
At JSM Group, we don’t just deliver power and communication solutions — we build the infrastructure that powers the future. Since 1998, we’ve grown into a high-margin, high-growth business backed by private equity, operating across gas, power, telecoms, and multi-utility frameworks.

What makes us a bit different?

Chartership support and investment in your development
Hybrid working and real work-life balance not just lip service

SCOPE OF ROLE
As a Senior Quantity Surveyor, you’ll report to our Chief Quantity Surveyor and play a key part in the commercial success of a wide range of civil engineering and utility contracts. You’ll lead both pre- and post-contract work from pricing and tendering through to valuations and final accounts. You’ll manage risk, drive value, and work closely with both operational and leadership teams. It’s a varied role, with a strong commercial voice at the table.

Own monthly valuations, applications for payment, and variations control
Produce accurate cost reports and CVRs across multiple high-value contracts
Implement and maintain strong commercial systems and recordkeeping
Proactively identify risks – and take action before they become issues
Collaborate with delivery teams to align commercial and project goals
Mentor junior team members and contribute to a positive team culture

WHAT IT TAKES

Strong commercial acumen and end-to-end project experience
Confident in NEC, JCT, and bespoke contracts
Skilled in setting up and managing site-based commercial systems
Hands-on leadership style with a proactive mindset
Comfortable negotiating and solving commercial challenges
Strong communicator with good stakeholder management skills
Proficient in Microsoft Office and commercial tools like Envision
