Design & Estimating Engineer – M&E / Integrated Systems

  • Portsmouth
  • £45000 - £65000 per annum
  • Full-Time

Are you a technically minded professional with strong design skills who also has experience in estimating?
We’re partnering with a forward-thinking industry leader known for innovation and quality, who’s looking for a Design Estimator to join their growing team.
This is a key role where you’ll help bridge the gap between client vision and technical delivery — transforming project concepts into accurate designs and costings that drive successful installations.
What You’ll Be Doing

  • Producing clear, accurate designs using CAD or Revit for a variety of building systems.
  • Preparing estimates and costings, translating designs into tangible project budgets.
  • Collaborating with Sales and Project Fulfilment teams to evaluate risks and identify practical solutions.
  • Reviewing project specifications and drawings to deliver cost-effective, compliant designs.
  • Supporting project documentation, including technical submissions and proposals.

What We’re Looking For

  • Proven experience with design tools such as CAD or Revit.
  • Prior estimating experience in a similar technical or building systems environment — you don’t need to be an expert, but solid exposure is essential.
  • M&E (Mechanical & Electrical) background is a bonus, but not mandatory.
  • Strong communication and organisational skills, comfortable collaborating across teams and with clients.
  • Relevant qualifications in Engineering, Quantity Surveying, or Construction Management are desirable.
  • Full UK driving licence (occasional site visits required).
  • CSCS / SMSTS, IOSH, or NEBOSH qualifications are a plus.
  • UK work eligibility required; we are unable to provide visa sponsorship.

Why Join? You’ll be part of a progressive, tech-driven business that values innovation, collaboration, and precision. Expect a role where your design skills and estimating experience are developed, your ideas are valued, and your work directly contributes to successful projects across the UK.
