Job Description
Citadel Source are delighted to be working on an exclusive basis with a high-impact, mission-led organisation to recruit a Finance Systems Implementation Manager on a fixed-term contract. This role represents a fantastic opportunity to lead on a business-critical transformation project, while also providing essential support to the finance function during a period of change. This is a hybrid role based near Bristol, offering the chance to make a tangible difference across the business by delivering a new integrated finance system that will support future growth, efficiency, and control.
About you
The ideal candidate will be an experienced finance professional with a strong track record of leading finance system implementations. You’ll be technically astute, process driven, and capable of bridging the gap between systems, finance and operational teams. You bring a proactive, hands-on approach and are comfortable managing system configuration, user testing, data migration, and change management — while also supporting the wider finance team with business-as-usual operations.
The role
This is a dual-purpose role:
- Leading the implementation of a new integrated finance system, ensuring the organisation achieves maximum benefit from the change;
- Supporting business-as-usual finance operations during the implementation phase to maintain continuity and control.
As a Finance Systems Implementation Manager, your role will include, but not be limited to:
- Lead and manage finance system implementation in collaboration with the system supplier, internal project teams, and finance colleagues
- Support supplier selection through expert input on systems, architecture, and control requirements
- Manage configuration discussions to ensure optimal future workflows and reporting outputs
- Analyse current and future state processes, working with suppliers to align them with system capabilities
- Oversee data migration: ensure quality and integrity of migrated data and validate successful transfer
- Lead on the design and implementation of a new chart of accounts to support internal and external reporting needs
- Plan and manage user acceptance testing (UAT), including test scripts and issue resolution
- Support integration of third-party systems into the finance platform and lead on resolution of technical issues
- Create user-friendly documentation, process guides and training materials
- Develop a cutover and go-live plan that balances transformation needs with operational continuity
- Champion adoption and embed new ways of working across finance and the wider organisation
- Contribute to lessons learned reviews and post-implementation improvements
- Support the finance team with operational tasks to free up capacity for others to focus on the project
Ideal Candidate Profile
Essential:
- Proven experience leading or supporting finance system implementations
- Strong technical understanding of finance processes and controls
- Track record of managing UAT, data migration, systems configuration, and go-live planning
- Experience documenting processes and training non-finance users
- Ability to manage multiple stakeholders across finance, IT, operations, and suppliers
- High attention to detail and process improvement mindset
- Comfortable with hybrid working, with regular on-site presence as needed
Desirable:
- Knowledge of change management and embedding new ways of working
- Familiarity with integrating finance systems with other platforms
- Previous experience in hands-on finance operations (e.g. management accounting, reporting)
What the client offers
- A values-driven organisation with a strong sense of purpose
- Key role in a high-impact systems transformation project
- Flexible, hybrid working (Bristol base)
- Collaborative culture and supportive team environment
- Competitive salary (dependent on experience)
- Fixed-term contract for the duration of the implementation project
