This includes root-cause analysis, remediation ownership, progress tracking, recovery validation and lessons learned. • Lead complex regional initiatives that strengthen technical acceptance resilience, improve monitoring and detection, remove recurring failure modes, and support technical acceptance stability. Apply disciplined project-management practices to define scope, milestones, dependencies, risks, governance, stakeholder communications and delivery plans. • Build strong internal partnerships across Networks, Operations, Sales, Market Development, and Strategy Teams; understand the broader ecosystem to influence decisions and drive alignment across differing priorities. • Build up and maintain clear KPIs, reporting, playbooks, escalation paths, operating controls and documentation for technical acceptance monitoring, investigation and remediation to prepare the team to scale. • Represent the UK Technical Quality of Acceptance function in governance forums, launch-readiness reviews, roadmap discussions and upda
