TECH-AGNOSTIC ROLE

Role: Integration Engineer

Position: Contract

Location: Bridgwater - SDC / HPC

Duration: Ongoing Contract

Pay: £345 p/d PAYE + 36 Days Annual Leave // £468.92 p/d Umbrella

Shape the Infrastructure of the UK’s Largest Construction Project

Rullion is supporting the HPC Delivery Integration Team in appointing a Civil Integration Engineer to help coordinate and de-risk infrastructure works across the site.

This role sits within the Safety & Schedule Assurance / PMO function, supporting the planning and coordination of major civil and infrastructure works outside the main buildings - including access routes, utilities corridors, drainage, earthworks, enabling works and supporting structures.

This is not a pure design role. It is a delivery-facing integration role focused on ensuring work is sequenced, resourced, and buildable before it hits site.

The Role

As an Integration Engineer (Civils), you will support the Area Integration Senior Engineer in ensuring that planned works - typically 16 weeks ahead of implementation - are credible, coordinated, and deliverable.

You will review construction sequences for civil infrastructure and external works, checking that:

  • Activities are logically sequenced
  • Interfaces with other disciplines are understood
  • Materials, plant and access arrangements are available
  • Constraints and clashes are identified early
  • Key schedule milestones are protected
  • You will work across multiple contractors and stakeholders, helping to resolve ‘hotspots’ and supporting Best for Project decision-making.

Principal Accountabilities

  • Review and validate construction sequences for infrastructure and civil works
  • Interrogate Primavera P6 schedules to identify risks, clashes and constraints
  • Assess readiness to commence works (labour, materials, plant, logistics)
  • Support resolution of delivery ‘hotspots’
  • Provide oversight of Delivery Work Packs (DWP) and Interface Data Sheets (IDS)
  • Use 3D / 4D tools (Navisworks / Synchro) to visualise and validate sequencing
  • Manipulate schedule data using Excel and present insights clearly
  • Work collaboratively with Engineering, Planning, Project Management, Procurement, Delivery and Commissioning teams
  • Support transverse issues across multiple areas and systems
  • Safety is the overriding priority. All work must align with HPC Life Saving Rules and Right First Time principles.

What You’ll Bring to the Project

We are specifically seeking a Civil Engineer with approximately 5+ years’ experience delivering complex infrastructure or large-scale construction projects.

You may currently be working as a:

  • Site Engineer
  • Civil Construction Engineer
  • Section Engineer
  • Infrastructure Engineer
  • Project Engineer (Civils)
  • But you understand how work actually gets built - and you can think beyond your immediate scope.

Essential Experience & Qualifications:

  • Degree in Civil Engineering or equivalent experience
  • Around 5 years’ experience on complex infrastructure or major projects
  • Strong understanding of construction sequencing and interfaces
  • Experience operating in regulated or high-safety environments
  • Knowledge of planning tools (Primavera P6 preferred)
  • Experience interrogating 3D models (Navisworks desirable)
  • Strong Excel and analytical skills
  • Confident communicator able to influence across disciplines

Desirable

  • Nuclear project experience
  • Experience under CDM regulations
  • IOSH Managing Safely (or equivalent)
  • Experience on large infrastructure programmes (power, rail, highways, energy, major civils)
