The Opportunity
This is more than just a job; it’s a mission.
As a Senior Project Planner, you’ll play a critical role in supporting our PMO and programme teams as they deliver some of the UK’s most complex defence projects.

Role Responsibilities
- Develop, maintain and control fully integrated master schedules using Primavera P6 for large, multi-workstream defence programmes.
- Ensure schedules are logically linked, baselined and structured in line with best practice, contractual requirements and internal governance.
- Provide proactive planning support including critical path analysis, what-if modelling and recovery planning.
- Identify, analyse and manage schedule risks and opportunities, integrating mitigations into programme schedules.
- Support bids and proposals by creating compliant, credible Primavera P6 schedules and planning inputs.
- Apply Earned Value Management to track schedule performance, support variance analysis and assess change impacts.
- Conduct and support Schedule Risk Analysis, including quantitative modelling, and present findings to senior stakeholders.
- Produce clear, high-quality schedule performance reports and dashboards for internal and customer reviews.
- Support internal and external audits related to planning, EVM and risk.
- Collaborate with engineering, supply chain, manufacturing and commercial teams to maintain schedule integrity.
- Provide mentoring and oversight to junior planners and act as a subject matter expert in Primavera P6, EVM and schedule risk management.
