• Lead the implementation phase for new customers, including managing enterprise project scope, budget, plan, resources, and timeline
• Build strong stakeholder relationships and communicate effectively with internal and external stakeholders to drive the project forward through visibility and accountability to reach customer goals
• Lead and collaborate with senior leadership and multiple departments across complex, cross-functional teams to ensure successful project delivery in enterprise environments
• Proven ability to engage with and influence C-level stakeholders, ensuring alignment and driving forward complex projects with multiple dependencies
• Proven expertise in navigating and managing complex, cross-functional projects across global teams with an emphasis on large enterprise environments
• Apply expertise in risk management to identify, assess, and mitigate project risks, ensuring smooth delivery of enterprise projects
