Job details

Salary: $120k to $130k/year Your New Role: The Manager, EPM Platform is a people-leadership role accountable for the governance, change management, and controls posture of the organization's EPM platforms, leading a team of two EPM Administrators covering OneStream, the organization's new EPM platform, and Hyperion, the legacy platform. Acting as the primary point of accountability between the business, the EPM Administrators, and third-party MSO consultants, the Manager quarterbacks all incoming requests from intake through resolution, triaging priority and complexity, assigning the appropriate resource, and ensuring work is delivered within a disciplined change management and controls framework. This role owns the Hyperion transition, with Hyperion no longer receiving operational updates after December 2026 while maintaining system access beyond that date. The successful candidate will establish and enforce the protocols that protect the integrity, security, and auditability of the EPM environment while ensuring the business experiences a single, well-managed front door for EPM platform needs. What You'll Need to Succeed: The successful candidate will serve as the single point of accountability for all OneStream-related requests from the business, triaging incoming requests for priority, complexity, and risk while determining the appropriate resourcing path between EPM Administrators, third-party MSO consultants, or a combination of both. You will engage directly with business stakeholders to clarify scope, gather requirements, set expectations, and provide status updates through resolution. You will act as the day-to-day relationship owner with third-party MSO consultants, directing their work, reviewing deliverables, and holding them accountable to timelines and quality standards. The role requires reinforcing EPM as the mandatory first point of contact for all OneStream requests and escalating complex, cross-functional, or resourcing conflicts with clear recommendations when required. You will own and continuously improve the change management framework for the OneStream platform, covering configuration, security, integrations, and reporting/planning logic. This includes establishing and enforcing formal change intake, approval, and sign-off processes, assessing business, technical, and risk impacts of proposed changes, maintaining a complete auditable change register, and coordinating release schedules to minimize disruption during key business cycles. The position is responsible for designing, implementing, and enforcing governance protocols and standard operating procedures for OneStream administration and system change. You will define, monitor, and enforce security, access, and segregation-of-duties controls, ensuring all administration and change activities meet internal controls, audit, and regulatory requirements. Regular reviews of system configuration, user access, and change history will also form part of the role. You will oversee platform and vendor management activities, including managing relationships with third-party MSO consultants, directing work, validating deliverable quality, overseeing Testing/QA and User Acceptance Testing (UAT), and ensuring system and control documentation accurately reflects the live-state configuration of the platform. As a people leader, you will directly manage two EPM Administrators supporting OneStream and Hyperion. Responsibilities include workload planning, performance management, coaching, professional development, recruitment, onboarding, and fostering collaboration across the EPM function. You will also own the Hyperion end-of-life transition plan and coordinate accessibility and operational update cut-off activities ahead of the platform sunset timeline. The role also includes ownership of budgetary and financial oversight of third-party MSO consultant spend, statements of work, invoice validation, effort tracking, and OneStream licensing costs in partnership with senior leadership. Education: Post-secondary Diploma or University Degree in Computer Science, Accounting/Finance, Business, or a related discipline. OneStream certification (Administrator or Design) is strongly preferred. Accounting and financial knowledge is considered a strong asset given the controls and compliance focus of the role. Experience: 5–7+ years of experience in EPM/financial systems administration, IT governance, or systems delivery, including hands-on OneStream experience. Hyperion or comparable EPM platform experience will also be considered. Demonstrated experience designing, implementing, or enforcing change management processes for enterprise systems. Experience designing or enforcing IT governance, controls, or compliance protocols. SOX or internal audit experience is considered an asset. Experience triaging and managing incoming business requests and translating business needs into scoped technical work. Experience managing third-party vendors, managed service providers, or consultants, including statements of work, deliverables, and performance accountability. Experience acting as a liaison between business stakeholders and technical teams. Prior people-management experience, including performance management and coaching, is preferred. Skills & Abilities: Strong understanding of change management practices and IT General Controls (ITGCs) as applied to enterprise and financial systems. Working knowledge of OneStream functionality, including consolidation, reporting, planning, and security, sufficient to triage and validate technical requests without requiring deep hands-on administration. Advanced proficiency with OneStream, Microsoft Excel, Word, and PowerPoint. Strong stakeholder management skills with the ability to set expectations and manage competing priorities. Proven ability to direct and hold external consultants and managed service providers accountable to scope, timelines, and quality. Excellent written and verbal communication skills with the ability to present technical and control concepts to varied audiences and enforce protocols diplomatically but firmly. Sound judgment in assessing urgency, impact, and risk while balancing competing business priorities. Work Conditions: Work is generally performed in an office environment located in Mississauga. Availability to work non-standard hours and flexibility concerning workdays is required. Irregular work hours may be necessary during month-end, quarter-end, budget, and forecast cycles. Off-hour support may also be required based on release schedules, operational activities, and project demands. What You'll Get in Return: You will have the opportunity to work with a talented team of professionals in a dynamic and supportive environment. The organization is offering competitive compensation, professional development opportunities, and the chance to make a significant impact through leadership of a critical enterprise platform and governance function.
