* Collaborate with clients, stakeholders, and the supply chain to manage interfaces and timelines.
* Provide commercial insight into programme impacts, production rates, and sequencing.
* Engage with commercial, design, and delivery teams to build realistic, achievable plans.
* Prepare and present progress reports, trends, labour efficiencies, and mitigation strategies.
* Support continuous improvement across planning processes and systems.
* Mentor and develop junior team members, sharing planning best practices.
About You
* Skilled in programme development from first principles – able to interpret drawings, perform quantity take-offs, apply output rates, determine durations, and logically sequence works.
* Confident communicator who can present complex programmes clearly to internal teams and external stakeholders.
* Experienced with planning software such as Primavera P6 and/or Asta Powerproject. Familiarity with Synchro, Navisworks, Power BI, or Asite is desirable.
* Strong contractual awareness, ideally with experience of NEC contracts.
* Engineering background preferred, with strong understanding of project lifecycle, including scope, schedule, cost, and quality management.
* Proven experience planning large-scale infrastructure or power projects, preferably substations and high-voltage works.
* Degree in Civil Engineering, Construction Management, or a related field. Chartered Membership of CIOB is desirable.
Why Join This Project?
* Long-term stability on a high-profile national infrastructure project.
* Career-defining opportunity with visibility, responsibility, and real impact.
* Supportive, inclusive culture where your contribution is recognised.
