Role overview

We’re looking for an indirect tax transformation manager with a primary focus on supporting the delivery of e-invoicing projects within our growing Digital Tax Consulting team. This is a client-facing role initially focusing on global e-invoicing and e-reporting mandates but will also provide the opportunity to grow and support other areas of our transformation business as required i.e. implementation of VAT solutions, working on ERP programs.

As a manager, you will support on the end-to-end delivery of e-invoicing engagements – from solution selection/design through to requirements gathering, configuration, testing and go-live while building client relationships. You’ll lead and help coach junior members of the team, and represent the practice in front of clients.

• Support with and help lead the end-to-end delivery of e-invoicing projects, managing scope, budget, risk and quality across the full project lifecycle

• Support, develop and help the senior team in maintaining alliances with third party technology providers

• Interpret country-specific e-invoicing mandates globally, including data and process impact/requirements and translating them into practical delivery actions for clients as part of projects

• Support and coach Senior Associates and Associates on projects through review, delegation and day-to-day guidance

• Own engagement risk and quality: apply firm policies and procedures, maintain appropriate documentation, and ensure compliance with internal quality standards and external regulatory expectations

• Drive business development: support in identifying and shaping new e-invoicing opportunities, along with supporting on proposals and bids

• Strengthen the wider practice — refine delivery methodology and support in building reusable accelerators and tools

Key skills and experience

Essential

• Experience delivering tax technology or e-invoicing implementation projects in a consulting, professional services, or in-house tax technology environment

• Deep working knowledge of e-invoicing and e-reporting regimes in at least one major region (EU, Middle East, Latin America or Asia-Pacific), and the ability to speak credibly about how mandates differ across jurisdictions

• Hands-on experience implementing/integrating at least one e-invoicing or tax compliance platform

• Proven ability to lead complex, multi-stakeholder technology engagements, managing budget, risk and quality without close supervision

• Strong stakeholder management

• People leadership experience: managing, coaching and developing team members across engagements

• Sound understanding of engagement risk, quality standards and regulatory expectations in a professional services environment

Additional advantageous experience

• Professional tax or accounting qualification (e.g. CTA, ACA, ACCA) or equivalent

• ERP experience (Oracle, Microsoft Dynamics, SAP S/4HANA) specifically for tax or e-invoicing purposes

• Experience leading global rollout programmes spanning multiple countries and jurisdictions

• Broader indirect tax technology exposure – VAT compliance solutions, Tax engines etc.

• Familiarity with data analytics or automation tools (Alteryx, Power BI, SQL, Python) to support e-invoicing data validation and reporting
