About the RoleThis is more than just a job — it’s an opportunity to be part of a transformative infrastructure programme with 15 years still to run, offering long-term stability, professional growth, and the chance to make a lasting impact.
As a Construction Engineer, you’ll play a pivotal role in ensuring the safe, compliant, and high-quality delivery of projects from pre-construction through to site completion. You’ll be at the heart of shaping how electrical works are delivered across road and infrastructure schemes, applying your specialist knowledge to influence design, drive constructability, and oversee on-site execution.
Working independently from framework contractors, you’ll ensure that every aspect of the build aligns with CP/CPS design standards, NEC contract requirements, and CDM regulations. From conducting early-stage design reviews to physically witnessing construction activities, your input will be critical in maintaining safety, quality, and efficiency.
You’ll collaborate closely with OPS teams to develop smart, cost-effective solutions that protect and enhance our assets. Your oversight will extend to supervising construction works, managing temporary works, and ensuring that health and safety, asbestos protocols, and final sign-offs are all completed to the highest standards.
This role offers excitement, challenge, and the chance to grow your career in a dynamic environment. With flexibility to work nights and weekends when needed, you’ll be part of a team that’s driving real change — and with over a decade of work ahead, you’ll have the stability to build something truly meaningful.
