£800 per day

MUST HAVE MEDIA AGENCY EXPERIENCE

The Role

The ERP Requirements Project Manager (Contract) will work within the Finance team at my client. This is a senior, fixed-term contract role responsible for leading the requirements definition phase of my clients migration from MediaOcean to Microsoft Dynamics 365.

The successful candidate will play a key part in design workshops, engage with senior stakeholders across the business, and ensure that all functional requirements are comprehensively identified, challenged, and documented before the technical build commences. This is a pivotal role that will directly shape the quality of our future finance systems and processes.

Background

My client is undergoing a significant period of Finance Transformation. This includes migrating trade to fewer legal entities, simplifying systems and making processes more standard.

A central pillar of this transformation is the migration of our core ERP platform from MediaOcean to Microsoft Dynamics 365. This move will modernise our financial infrastructure, improve data integrity, and create a scalable platform to support continued growth.

To deliver this successfully, we need a senior finance professional who can take control of the requirements phase with authority - someone who understands both the technical landscape of Microsoft Dynamics 365 and the commercial/operational realities of working within a large, complex media business.

Approach

In line with our wider Finance Transformation principles, this role will adopt a people-first and continuous improvement mindset, ensuring that:

• Requirements reflect the genuine needs of our finance teams and are

designed for willing adoption, not simply a like-for-like replication of existing processes

• Legacy ways of working are critically challenged, with the new system seen as an opportunity to embed best practice from the ground up including leveraging automation

• All key stakeholders are meaningfully engaged throughout the requirements process, with clear governance and sign-off at every stage

• The solution is aligned to a single source of truth, enabling accurate, timely, and insightful financial reporting across the business.

What You'll Do:

• Be a key contributor to the requirements workstream for the Microsoft

Dynamics 365 implementation.

• Bring deep Microsoft Dynamics 365 expertise to challenge and shape

requirements, ensuring the business benefits from best-practice system design rather than replicating existing process inefficiencies

• Lead current-state process reviews, working with finance teams to

understand existing MediaOcean workflows and identify improvement

opportunities as part of the transition to Dynamics 365

• Drive gap analysis between current MediaOcean functionality and Microsoft Dynamics 365 capabilities, proactively surfacing risks and proposing pragmatic solutions

• Produce and maintain high-quality requirements documentation,

including Business Requirements Documents (BRDs), process flow diagrams, and prioritised user stories, to a standard ready for handover to the technical implementation team

• Act as the senior point of contact between Finance, IT, and implementation partners during the requirements phase, ensuring alignment and resolving conflicting priorities with authority

• Identify, manage, and escalate risks and dependencies that could impact the integrity of the design or downstream delivery milestones

• Prepare and present materials for senior stakeholder and governance

forums, providing clear and concise updates on requirements progress,

decisions needed, and outstanding risks

• Contribute to data migration planning, advising on data structures,

cleansing requirements, and field-level mapping from MediaOcean to

Microsoft Dynamics 365

What You'll Bring:

To succeed in this role, you will have:

• A recognised accountancy qualification (ACA, ACCA, CIMA or equivalent)— essential

• Hands-on experience of at least one full Microsoft Dynamics 365

Finance & Operations implementation at a senior level, whether as a project lead, senior functional consultant, or requirements owner — essential

• Previous experience within the media industry, with a strong

understanding of media-specific financial processes including client billing, agency revenue recognition, inter-company recharges, and supplier management — essential

• Demonstrable experience owning a requirements workstream end-to-end, including planning, facilitation, documentation, and stakeholder sign-off

• The gravitas and confidence to challenge existing ways of working and advocate for best-practice solutions, even where that requires difficult conversations

• Exceptional stakeholder management skills, with experience engaging and influencing at Finance Director level and above

• Outstanding written and verbal communication skills, with the ability to translate complex system design concepts into clear, accessible language for non-technical audiences

• A highly organised and self-directed working style, with the ability to

structure and manage a demanding workstream independently within a fixed-term engagement

• Proven ability to work at pace and under pressure, delivering high-quality outputs to immovable deadlines

What We Would Love You to Have:

• Direct experience of MediaOcean and a strong understanding of its data structures, chart of accounts, and financial workflows

• Exposure to data migration projects, including data mapping, cleansing strategies, and validation frameworks

• Knowledge of Power BI or other reporting and analytics tools that

integrate with Microsoft Dynamics 365

• Experience working alongside business architecture or solution design teams to ensure the right solution is being built, not simply the one the business initially asks for
