Enterprise Project Manager in London

Build your future with Sovos. If you're seeking a career where innovation meets impact, you've come to the right place. As a global leader, Sovos is transforming tax compliance from a business requirement to a force for growth while revolutionising how businesses navigate the ever-changing regulatory landscape. At Sovos, we're dedicated to more than just solving compliance challenges – we're committed to making a positive and lasting difference in everything we do.

Our purpose-built systems provide the tools you need to thrive in a world where governments demand increased visibility, faster reporting and greater control over business processes. Excited about the possibilities? So are we! Don’t worry if you don't check all the boxes – apply anyway! We're focused on hiring the right people, not just the "right" resume. It's not about what you've done elsewhere; it's all about what you're capable of doing here.

The Work You'll Do:

• 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 C-suite sponsors — throughout the engagement lifecycle.
• Develop and maintain detailed project plans, risk registers, issue logs, and status reports; proactively surface risks and drive resolution before they become escalations.
• 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, and drive change orders when client requests exceed agreed SOW boundaries.
• Coordinate cross-functional Sovos resources — Solution Consultants, Technical Consultants, SAP specialists, Regulatory, and Product — to deliver against project commitments.
• Track and report project hours against PS retainer balances; proactively communicate burn-down status and initiate retainer expansion conversations at appropriate thresholds.
• Ensure all project data, time entries, and status records are accurately maintained in Cloud Coach and Sovos project management tooling in real time.
• Manage Hypercare periods post-go-live and execute formal project handover to Sovos Customer Support.
• Contribute to the continuous improvement of PS delivery methodology, SOW templates, onboarding playbooks, and project governance frameworks.
• Provide structured feedback to Product Management on implementation patterns, recurring defects, and enhancement opportunities observed across the client portfolio.

What We Need From You:

• 7+ years of project management experience, with at least 4 years delivering enterprise SaaS implementations in a client-facing Professional Services environment.
• Demonstrated experience managing complex, multi-stakeholder implementations in the tax compliance, e-invoicing, VAT, or regulatory technology space — this is a differentiating requirement.
• Proven track record managing projects with enterprise clients (500M+ revenue) across multiple countries and time zones concurrently.
• Experience with SAP-integrated implementations (SAP ECC, S/4HANA, or Process Orchestration) is strongly preferred.
• Hands-on experience with retainer-based PS engagements, including scope management, change order discipline, and hour burn-down governance.
• Familiarity with EMEA e-invoicing mandates — including France (PPF/PDP), Germany (XRechnung/Peppol), Poland (KSeF), and/or Turkey (e-Fatura/e-Arşiv) — is a significant advantage.
• Exceptional stakeholder management — able to build trust with client executives and navigate competing priorities without losing delivery momentum.
• Strong commercial acumen — understands the relationship between project delivery, revenue recognition, and margin, and manages accordingly.
• Proactive risk management mindset — identifies and escalates issues early, documents decisions, and drives accountability without being asked.
• Clear, structured communicator — written and verbal — capable of adapting tone and detail level for technical teams, client project managers, and executive sponsors alike.
• Comfortable operating with ambiguity and driving clarity in fast-moving, multi-mandate environments where priorities can shift quickly.
• Proficiency with project management tooling (e.g. Cloud Coach, Salesforce, Jira, or equivalent PSA/CRM platforms).
• PMP, PRINCE2, or equivalent project management certification preferred.
• Bachelor’s degree in Business, Information Systems, Finance, or a related field; equivalent experience considered.
• Fluency in English required; proficiency in French, German, Dutch, Spanish, or Polish is a meaningful advantage given the client base.
