JSM Group
JSM Group designs and builds the power networks and digital infrastructure that clients across the UK, Europe and beyond depend on — from high-voltage grid connections and critical utilities to data centres and renewable energy. Our civil, power and digital engineers work under one roof, giving clients one team from design to energisation, with the technical, commercial and consenting risk managed from day one.
Belonging here isn’t accidental — it’s engineered. Our values of personal responsibility, sound judgment and drive, shape how we work, and you’ll get the work to stretch you and the support to develop fast. See life at JSM at careers.jsmgroup.com.
The Role
You’ll produce accurate, detailed pricing for multi-disciplinary schemes — cable installation, civils, reinstatement, utility connections, enabling works and specialist solutions such as HDD — giving us the confidence to bid sharply and deliver profitably.
What You’ll Do
- Review tender documents, anticipate risk early and shape the bid strategy with colleagues.
- Build first-principles estimates in Causeway (and Excel) covering labour, plant, materials, subcontractors, traffic management and Local Authority fees — keeping cost models current.
- Gather the inputs behind a robust price — Gazetteer data, permits and restrictions from Street Works and Planning, quotations from Procurement, and outputs and programme from Delivery, including site surveys where needed.
- Compile tender submissions, issue and evaluate subcontract enquiries, and support final bid review and sign-off with senior managers.
- Lead pre- and post-tender commercial activity, from client clarifications to BAFO reviews, then hand won schemes over to the Delivery team and QS.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.

- Good knowledge of utility contracting and highways reinstatement
- A degree or HND/HNC in civil engineering or at least 5 years in a similar utilities-focused estimating role

You’ll thrive here if you
- Take ownership of your work and your development
