At JSM Group, we are a leading specialist infrastructure engineering company. We design and install the complex power networks, digital infrastructure and specialist systems a future-focused worldwide marketplace needs — from high-power grid connections to critical utilities, data centres to renewable energy.
Our full turnkey solution teams manage the full scope of complex infrastructure projects, helping clients deliver at speed, on time, and with reduced legislative, technical and commercial risk.
You'll join JSM's commercial team, reporting to our Chief Quantity Surveyor. Since 1998, JSM has grown into a high-margin, high-growth business backed by private equity, delivering long-term frameworks for major clients across gas, power, telecoms and multi-utility infrastructure.
The commercial team leads from the front rather than reporting the numbers after the fact, working closely with operational delivery, site management and leadership to keep cost, risk and programme aligned across a portfolio of civil engineering and utility contracts. There's a clear path to progress into Commercial Manager roles, chartership support along the way, and hybrid working that's a genuine mix of site, office and home rather than a policy on paper.
As Senior Quantity Surveyor, you'll report to the Chief Quantity Surveyor and take commercial ownership of a portfolio of civil engineering and utility contracts — from pricing and tendering through to valuations and final accounts. You'll manage risk, drive value, and act as the commercial voice at the table for both operational and leadership teams.
Day to day, you will:
This role is hybrid, with regular travel between site and office as contracts require.
You'll do well here if you recognise yourself in this:
If you meet most but not all of the above, we'd still like to hear from you. We'll look at what you've delivered and what you're capable of, not just the list.
At JSM Group, we're not just shaping the future of utilities, we're raising the bar for what a great place to work looks like.
Our values aren't words on a wall. They drive every decision we make and every project we take on, pushing us to go further, do better, and leave a real mark on the industry.
We want people who are hungry to grow, ready to take on complex challenges, and excited to work alongside clients and partners who are changing the landscape of the utility sector across the UK, Europe and beyond.
In return, we give you the room to develop fast, the work to stretch you, and the platform to build a career that actually means something.
In addition to an industry-competitive salary, we offer:
