Build Your Future With Us

The digitization of tax compliance is fundamentally changing global commerce and how businesses need to operate and grow. Governments now have real-time visibility into business data, creating new challenges and new opportunities for organizations around the world. At Sovos, we're transforming tax compliance from a business requirement into a driver of growth through AI-powered technology that delivers the accurate, real-time insights businesses need to make smarter decisions.

We're solving more than today's tax compliance challenges. We're helping reshape global economies by enabling organizations to navigate increasingly complex and rapidly changing regulatory environments with confidence – and helping communities thrive.

AI is accelerating what's possible, enabling tax and technology professionals to more effectively drive critical regulatory decisions. That's where Sovos excels, combining intelligent technology with human expertise to help customers stay ahead of change.

Don't worry if you don't check every box. We're focused on hiring great people, not perfect resumes. It's less about what you've done elsewhere and more about what you're capable of doing here.

The Role

At Sovos, we're building the future of tax compliance technology across Europe. We're looking for a Senior Project Manager to join our European Professional Services team, with the ability to be based in the United Kingdom, Netherlands, or Spain. This is a senior delivery role for someone who understands the complexity of enterprise SaaS implementations and brings deep familiarity with tax compliance, e-invoicing, or regulatory technology. You'll own end-to-end delivery of complex, multi-country implementations for enterprise clients across EMEA, operating with autonomy and directly impacting client satisfaction and the reputation of Sovos Professional Services in Europe.

More specifically, you will:

• Own end-to-end project delivery for enterprise e-invoicing and tax compliance implementations across multiple EMEA countries simultaneously.
• Serve as the primary point of contact and escalation for client stakeholders, from project teams to executive sponsors, throughout the engagement lifecycle.
• Lead structured project governance, including weekly status meetings, monthly steering committee sessions, and go/no-go decision processes, in alignment with Sovos delivery methodology.
• Manage project scope rigorously; identify, document, anddrive change orders when client requests exceed agreed statement-of-work boundaries, and track project hours against retainer balances.
• Coordinate cross-functional Sovos resources (Solution Consultants, Technical Consultants, SAP specialists, Regulatory, and Product teams) to deliver against project commitments.
• Develop and maintain detailed project plans, risk registers, issue logs, and status reports; proactively surface risks and drive resolution before they become escalations, leveraging AI tools to improve efficiency and insights where appropriate.
• Contribute to continuous improvement of Professional Services delivery methodology, statement-of-work templates, onboarding playbooks, and project governance frameworks based on insights from your client portfolio.

• You have hands-on experience with retainer-based Professional Services engagements, including scope management, change order discipline, and hour burn-down governance.
• You're an exceptional stakeholder manager, able to build trust with client executives and navigate competing priorities without losing delivery momentum, and you bring strong commercial acumen around project delivery, revenue recognition, and margin.
• You're a proactive risk manager and clear, structured communicator (written and verbal), capable of adapting tone and detail level for technical teams, client project managers, and executive sponsors alike, and you're comfortable operating with ambiguity and adapting quickly as client needs evolve.
• You're proficient with project management tooling (e.G. Salesforce, Jira, or equivalent PSA/CRM platforms); PMP, PRINCE2, or equivalent project management certification preferred; Background in Business,Information Systems, Finance, or equivalent experience.
