• Support user provisioning, de-provisioning, and access changes across the application landscape, with a focus on timeliness, accuracy, and compliance with approval workflows.
• Perform security design reviews and ongoing monitoring to identify access risks, segregation of duties conflicts, and control gaps, and recommend practical remediation actions.
• Coordinate periodic access reviews and recertification activities with business owners, ensuring user access remains appropriate and exceptions are documented, tracked, and resolved.
• Partner with business stakeholders, application support teams, and audit partners to support investigations, root-cause analysis, control evidence requests, and continuous improvement of the finance systems security model.

What we are looking for:

• Demonstrated experience supporting application security, identity and access management, or user access governance within enterprise systems. • Understanding of finance processes such as Record-to-Report, Procure-to-Pay, Acquire-to-Retire and Contract-to-Cash and related access control requirements.

• Knowledge of role-based access design, segregation of duties, privileged access considerations, and periodic access review practices.

• Experience operating in a controlled environment with audit, compliance, and governance expectations across multiple business units and systems.

• Proven ability to assess security risks, investigate access issues, and support remediation activities in partnership with functional and technical teams.

• Ability to translate business requirements and control expectations into sustainable security roles, access models, and process improvements.

• Strong analytical, documentation, and stakeholder management skills, with the ability to communicate clearly across business, technology, and audit teams.

• Working knowledge of integrated application environments, including how security roles, workflows, and data flows interact across upstream and downstream systems.

What you will bring:

• 5+ years of experience in application security, user access administration, identity and access management, or functional support roles within enterprise environments.

• Bachelor’s degree in Information Systems, Computer Science, Business, Finance, or a related discipline, or an equivalent combination of education and experience.

• A strong controls mindset, with experience applying least-privilege, role-based access, segregation of duties, and audit-ready documentation practices.

• Hands-on experience supporting security or access administration for one or more enterprise platforms such as: • Hyperion / Oracle EPM applications

• PeopleSoft Financials and related workflows

• Coupa and other procure-to-pay platforms

• Concur or other travel and expense applications

• Oracle Transportation Management (TMS) or comparable logistics platforms

• Planview, Lucernex, ARCS, or other enterprise SaaS applications

• Experience supporting access governance processes such as provisioning workflows, role maintenance, recertification, segregation of duties analysis, and audit or compliance reviews.

• Professional certifications such as CISSP, CISM, CRISC, Security+, or ITIL are considered an asset.
