You will work closely alongside the Global Solution Lead for Consolidation and report into the broader OneStream leadership structure.

• Own the functional design, optimisation, and ongoing evolution of Forecasting and xP&A solutions on the OneStream platform
• Act as the primary partner to Forecasting and xP&A business owners across Group Control, operational finance, and supply chain functions

• Support post-change evaluations, performance monitoring, and insight-led recommendations
• Develop training materials and provide guidance to drive adoption and best practice usage

Ways of Working

• You will be part of a small, senior OneStream SME group, each owning distinct functional areas of the platform
• End-user first and second-line support is handled by an external provider
• Complex technical development is led by a dedicated OneStream architect and developer team
• The role is heavily business-facing, focused on solution design, prioritisation, and value delivery rather than technical build
• From time to time, you may act as project lead for medium or large change initiatives

Candidate Profile

• Minimum 5 years' experience working with enterprise EPM platforms in a functional or hybrid role
• At least 2 years' experience working with forecasting, planning, or xP&A capabilities within an EPM environment
• Strong working knowledge of OneStream is highly preferred
• Solid understanding of forecasting, scenario modelling, and operational planning processes
• Experience translating complex business requirements into robust system designs

• Certification in OneStream, project management, or agile methodologies is advantageous but not essential

Details

• Permanent position with competitive salary and benefits
• Role available in the Stockholm and Gothenburg regions with flexible hybrid working arrangements
• Opportunity to work with a sophisticated, business-critical OneStream platform supporting enterprise-wide forecasting and xP&A
• High-impact role influencing how the organisation plans, models, and responds to future scenarios
