About the Role
As Internal Audit Manager, you will join a global audit team of ten experienced internal auditors, including an IT lead Auditor based in Amsterdam. You will be based in Chicago alongside another Auditor. Optiver is currently in transition and moving towards a more globally integrated IT operating model, so you will be involved not only in assessments of local entities but also regional and global functions, providing insights to the Management Board and Supervisory Board.
Assessments cover the entire IT spectrum of the organization, from Information Security to IT Operations and from IT risks in HR or payment systems to IT risk in trading systems. You will also support other Group Auditors on broader audit topics when IT expertise is needed, giving exposure to business areas such as HR, Legal, Operations, Trading and Finance. The common purpose is to enhance and safeguard organizational value by conducting risk-based and objective audits, offering advice, and providing valuable insights.
The Group Audit team, originally based exclusively in Amsterdam, is expanding its presence in key regional offices, including Chicago for Transatlantic business. The team performs audits, assessments and special projects across Optiver offices including Amsterdam, Shanghai, London, New York, Mumbai, Austin, Hong Kong, Singapore, Sydney and Taipei. You will visit Optiver offices two or three times per year — primarily in the US — for one to two weeks at a time, and will also execute audits remotely.
