  • Partner with functional leaders to ensure readiness across quality systems, training, supply chain, manufacturing systems, facilities, and operational processes.
  • Maintain visibility of programme risks, issues, and key milestones, helping teams resolve challenges before they impact delivery.
  • Support the transition from commissioning and qualification activities through to operational readiness and routine manufacturing.
  • Drive operational rehearsal activities, scenario planning, and contingency preparedness.
  • Build strong relationships across site functions to enable collaboration and alignment.
  • Support executive communications and reporting, providing clear insights on progress, risks, and priorities.
  • Identify opportunities to improve readiness frameworks, governance processes, and ways of working while capturing lessons learned for future initiatives.

  • Experience supporting facility start-up, operational readiness, technology transfer, process validation, PPQ, product launch, or commercial manufacturing activities.
  • Proven track record of leading or coordinating complex cross-functional programmes within a regulated manufacturing environment.
  • Strong stakeholder management and influencing skills with the ability to build credibility across all levels of an organisation.
  • Demonstrated ability to manage competing priorities, navigate ambiguity, and deliver results in a fast-paced environment.
  • Excellent communication, presentation, planning, and organisational skills.
  • Experience preparing updates, recommendations, and risk assessments for senior leadership teams.
