  • A significant part of your contribution will involve mentoring FP&A and technical teams. You will share your expertise on architectural best practices, code quality, and system scalability, thereby building organizational capacity and deep expertise within the OneStream platform.
  • You will be at the forefront of evaluating and implementing emerging OneStream technologies, such as BI Relational Blend, Genesis, and Sensible AI. This proactive approach aims to transform our financial reporting from static analysis to predictive insights, driving more strategic business decisions.
  • This role offers a unique opportunity to influence the direction of financial systems at a leading global analytics software company. You will work with cutting-edge technology and collaborate with a world-class team, contributing directly to FICO's ambitious growth strategy.
  • The Principal OneStream Architect will act as a subject matter expert, guiding the technical vision and execution for the OneStream platform. This includes staying abreast of new features, best practices, and industry trends to ensure FICO remains at the forefront of financial technology.
  • You will be responsible for the technical integrity and scalability of the OneStream solution, ensuring it meets the evolving needs of the business. This involves proactive identification of potential issues and the development of strategic solutions.
  • The role demands a strong understanding of financial processes, including budgeting, forecasting, and regulatory reporting, to ensure the OneStream architecture effectively supports these critical functions.
  • You will play a key role in change management, ensuring smooth transitions for new features, integrations, and system upgrades, while minimizing disruption to finance operations.
  • Collaboration with cross-functional teams, including IT, data engineering, and business intelligence, will be crucial to ensure a holistic and integrated approach to financial systems management.
  • The Principal OneStream Architect will contribute to the development of a multi-year roadmap for the OneStream platform, aligning technology investments with business priorities and strategic goals.
