Your journey with us

Are you an experienced transformation professional ready to help organisations redesign how tax and finance operate?

We’re looking for a Business Process Transformation Manager – Tax & Finance to join our Tax Technology & Transformation team, a dynamic group helping leading organisations reinvent their operating models through smarter processes, digital tools, data-driven insights and effective change.

You do not need to be a tax specialist. You may bring experience from finance transformation, business process improvement, shared services, ERP-enabled change or a related field, combined with a practical understanding of how tax requirements connect with finance processes, data and systems.

As part of the TTC team, you’ll help clients rethink and redesign tax operating models in their broader finance and business context. You’ll work closely with multidisciplinary teams to deliver transformation projects across strategy, governance, organisation, processes, data, technology and change.

You’ll bring structured problem-solving, strong stakeholder skills and a pragmatic understanding of how technology, including AI, can improve ways of working. You will also coach junior colleagues and help build the team’s transformation capabilities.

Key Responsibilities

• Lead workstreams within tax and finance operating-model transformation projects, from current-state assessment through future-state design and implementation.

• Assess end-to-end business processes and identify opportunities for simplification, standardisation, automation, improved controls and clearer ownership.

• Translate strategic objectives into practical operating-model components, including governance, roles and responsibilities, process design, service delivery, data and technology requirements.

• Collaborate with tax, finance, IT, data and business stakeholders to ensure solutions are practical, integrated and aligned with wider transformation initiatives.

• Support ERP-enabled transformation from a business-user perspective, helping clients connect process and reporting requirements with the capabilities of major ERP platforms.

• Identify and articulate practical AI and automation use cases, including examples of how these technologies can improve productivity, quality, insight or user experience.

• Prepare and facilitate workshops, interviews and working sessions with client stakeholders, and communicate recommendations clearly to senior audiences.

• Support change management, implementation planning and adoption of new processes, tools and ways of working.

• Coach and guide junior team members, providing day-to-day direction, constructive feedback and quality review.

• Contribute to proposals, thought leadership, methodologies and the continued development of the TTC team’s transformation offering.

• Stay current on developments in business process transformation, tax and finance technology, ERP, data, AI and digital operating models.

Let's talk about you

• Six to ten years of overall professional experience, including at least five years in business process transformation, finance transformation, operating-model design, technology-enabled change or a comparable role.

• A background in tax is nice to have but not required. Experience in finance, controllership, shared services, enterprise transformation or consulting is equally relevant, provided you have an understanding of tax touchpoints and are interested in developing this further.

• Demonstrated experience analysing and redesigning end-to-end processes, defining future ways of working and supporting implementation.

• Working knowledge of major ERP systems from a business-user or process perspective, such as SAP, Oracle or Microsoft Dynamics. Deep technical configuration experience is not required.

• Tech-savvy and comfortable adopting digital tools. You understand the fundamentals of AI, can use AI tools responsibly in day-to-day work, and can explain realistic efficiency opportunities and limitations.

• Strong analytical and problem-solving skills, with the ability to connect strategy, processes, people, data and technology.

• Confidence facilitating workshops and engaging with stakeholders across tax, finance, IT and the wider business, including senior stakeholders.

• Experience coaching or supervising junior colleagues and taking ownership for the quality and timely delivery of team outputs.

• A proactive, collaborative and pragmatic mindset, with the curiosity and adaptability needed to work across different industries and transformation challenges.

• Fluent in English and in either Dutch or French. Knowledge of both Dutch and French, or of additional European languages, is considered an asset.

What We Offer

• The opportunity to work on complex tax and finance transformation challenges across different industries.

• A collaborative environment that values innovation, creativity and learning.

• Access to leading tax, finance, ERP, data and AI-related technologies and methodologies.

• A strong focus on professional development, with learning opportunities in transformation, technology and leadership.

• A competitive salary and benefits package tailored to your experience and ambition.
