Cost Control Application System Administrator

Mississauga, Ontario, Canada

Overview

The Project Cost Control System Administrator is responsible for back-end administration, configuration, maintenance, and technical support of EcoSys as the enterprise platform for project cost management and control. EcoSys serves as the primary project management user interface, requiring strong alignment to standardized project structures and disciplined data quality.

This role provides technical troubleshooting and platform stewardship—including access/security, configuration, integrations, and issue resolution when technical defects or system behaviors prevent users from completing work.

Your role

  • EcoSys Platform Administration: Configure, maintain, and oversee platform health, core objects, and governance to support standardized cost and project controls aligned with ERP (Oracle).
  • Back-End Technical Support: Troubleshoot and resolve system defects, perform root-cause analysis, coordinate fixes, and maintain incident runbooks/knowledge articles.
  • Security & Access Management: Administer user roles and permissions using least-privilege principles; provide audit support and backup admin coverage for standalone instances.
  • Integrations & Data Quality: Monitor and support EcoSys–ERP integrations, ensuring accurate, timely, and reconciled data for finance and reporting stakeholders.
  • Operational Enablement: Partner with Project Administrators and stakeholders by providing technical escalations, documentation, and guidance on approved training resources.
  • Continuous Improvement: Identify automation opportunities and recommend platform enhancements to reduce manual effort, improve reporting reliability, and strengthen cost control.
