- Own metadata architecture, dimensional design, optimisation, and best practice governance.
- Create new models and enhancements using Analytic Blend, PFx, Task Manager, Application Control Manager, and other v9 capabilities.
- Collaborate closely with Group Finance and FP&A to translate functional requirements into scalable technical solutions.
- Lead workshops, technical design sessions, and solution walkthroughs.
- Provide expert recommendations on process improvement, modelling, and architecture.
Core Experience Requirements
- Extensive hands‑on experience developing OneStream solutions (v8/v9) within complex, multi‑currency, multi‑entity group environments.
- Strong technical capability across BR/Calc Scripts, Vb.net, Extender Rules, Dashboards, Cube Views, Data Management, and Workflow.
- Solid understanding of consolidation models, including FX, intercompany, eliminations, and minority interest.
- Experience building planning models such as driver‑based planning, forecasting, and allocation frameworks.
- Demonstrable ability to design scalable metadata structures and optimise cube performance.
- Robust integration experience.
- Excellent communication skills with the confidence to partner effectively with Finance stakeholders.
- Familiarity with Analytic Blend, Task Manager, PFx, and Application Control Manager.
- Understanding of end‑to‑end finance processes (close, consolidation, reporting, planning).
- Background in consulting or large‑scale EPM/CPM implementations.
Qualifications
- Degree in Finance, Accounting, Computer Science, or a related field.
- Professional accounting qualification (ACCA/CIMA/ACA/FCCA) is advantageous but not essential.
- OneStream certifications or formal training are highly valued.
