Looking to take your project management career to the next level? Interested in a role where you\’ll operate as a strategic partner, overseeing the delivery and implementation of e‑invoicing software for a portfolio of global multinational clients? This could be the opportunity for you.
Thomson Reuters is seeking a Senior Project Manager to join our ONESOURCE Pagero Professional Services team. In this senior role, you\’ll have end‑to‑end accountability for the successful implementation of e‑invoicing solutions for large, complex, multi‑national organizations. You will lead and coordinate internal and external project teams – from project initiation through to completion – ensuring delivery within agreed scope, timeline, and budget. Partnering closely with senior stakeholders across North America and Europe, you\’ll leverage your advanced communication, leadership, and organizational skills to drive a portfolio of concurrent projects to successful outcomes.
This is an excellent opportunity for a proactive and results‑driven project manager with a deep understanding of project management methodologies and a strong track record of delivering complex, cross‑functional initiatives. You\’ll thrive in a collaborative environment, provide clear direction and guidance to teams, and excel at anticipating, escalating, and mitigating project and program‑level risks.

• Proactively identify, assess, and mitigate project and program risks, implementing robust governance and escalation paths.
• Lead decision‑making and problem‑solving activities, facilitating resolution of complex issues across teams and stakeholders.
• Ensure all project documentation, including plans, requirements, and lessons learned, is complete, current, and appropriately stored and shared.
• Champion best practices, standards, and continuous improvement in project management across the team, mentoring and supporting more junior colleagues where appropriate.
