Internal Audit Manager

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. As a result, 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.  The assessments cover the entire IT spectrum of our organization: from Information Security to IT Operations and from IT risks in HR or payment systems to IT risk in trading systems. Additionally, you will support other Group Auditors on broader audit topics when IT expertise is needed, giving you exposure to a wide array of 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.

While the Group Audit team was originally based exclusively in Amsterdam, the team is now expanding its presence in key regional offices, including Chicago for Transatlantic business, to enhance and scale the execution of audit activities.The team performs a range of audits and assessments and, when required, special projects across Optiver offices, including Amsterdam, Shanghai, London, New York, Mumbai, Austin, Hong Kong, Singapore, Sydney and Taipei.

As part of the team, you will visit Optiver offices two or three times per year - primarily in the US - for periods of one to two weeks and will also execute audits remotely.
