You will work at the interface of delivery, governance, and client assurance, translating scope and constraint into schedule logic that holds up under audit. This is a role for someone who wants their planning judgement trusted at the highest levels of a programme.

• Lead schedule risk analysis, including quantitative techniques such as Monte Carlo simulation

• Produce clear planning reports and dashboards for governance boards, senior stakeholders, and client reviews

• Support assurance reviews, audits, and gate readiness assessments to defence and government standards

• Strong analytical skills, with the ability to interrogate schedule logic and identify critical path risk

• Clear, precise communication suited to senior governance and client audiences

• Sound judgement under time pressure, with the discipline required for security-sensitive delivery

• Collaborative style, able to align engineering, commercial, and delivery stakeholders

Qualifications

• Degree in engineering, construction management, project management, or a related discipline (or equivalent experience)
