Job description

THE TEAM

At JSM Group, we deliver integrated power and communications solutions across the UK. Since our founding in 1998, we’ve grown into a high-margin, high-growth organisation backed by significant private equity investment. Our Gas Division is a key area of the business, and we’re now looking for a Senior Quantity Surveyor to help us continue delivering high-quality, commercially successful projects.

SCOPE OF ROLE

As a Senior Quantity Surveyor, you’ll report to the Chief Quantity Surveyor and be responsible for overseeing the commercial and contractual aspects of a wide range of civil engineering and utility contracts. This role spans both pre- and post-contract responsibilities, from tendering through to contract management, valuation, and cost control. You will also lead the commercial administration of projects across frameworks and high-value standalone contracts.

HOW YOU'LL SUCCEED

• Managing subcontractor relationships, including negotiating rates, reviewing packages, agreeing variations, and assessing applications.
• Leading on tender preparation and submission, including cost analysis, reviewing T&Cs, and evaluating subcontract responses.
• Overseeing contract administration, including monthly valuations, payment arrangements, variations control, and claim assessments.
• Producing detailed cost reporting and monthly CVRs, tracking cost vs value across all assigned contracts.
• Implementing commercial reporting systems and maintaining accurate records throughout each project lifecycle.
• Identifying commercial and contractual risks early and taking proactive measures to manage and mitigate them.
• Working collaboratively with operational teams to align commercial strategy and project delivery.
• Supporting the development and mentoring of junior commercial team members.

WHAT IT TAKES

• Experience in civil engineering or utility contracts (gas sector preferable but not essential).
• Proven ability to manage the full commercial lifecycle of multiple projects.
• Strong knowledge of contract forms (NEC, JCT, and bespoke).
• Ability to lead and manage site-based commercial reporting systems.
• Strong problem-solving and negotiation skills.
• A collaborative, ‘hands-on’ approach to commercial leadership.
• Strong organisational skills and attention to detail.
• Proficiency in Microsoft Office and cost control systems (e.g. Envision).
• Strong communication and interpersonal skills, with customer awareness and commercial insight.

WHAT WE OFFER YOU

We truly value your work, time, and skills! In return, we will offer you a competitive salary and some additional benefits to support your professional growth, including:

• Participation in mentoring and coaching programmes.
• 28 days of holiday (excluding bank holidays).
• 2 paid volunteering days a year.
• Continuous training and development, in both technical and business skills.
