Job Description

We are seeking a highly motivated and collaborative professional to join our Global Risk & Controls team, focused on supporting our European business. This role is a key liaison between regulatory developments, audit requirements, and business execution, translating complex regulatory and audit expectations into practical, scalable controls and ensuring audit readiness across the region. 

This role will be based in Warsaw, Poland, and will be a hybrid position. 

We will count on you to: 

  • Partner with Compliance and Legal to interpret regulatory and policy requirements across Europe, assess business and control impacts, and drive audit readiness. 

  • Collaborate with Operations, Technology, Finance, Risk, and other corporate functions to design and implement practical, sustainable preventative and detective controls. 

  • Serve as a primary liaison for Internal and External Audit — support planning, walkthroughs, testing, documentation, and timely issue resolution. 

  • Lead or support remediation efforts after audits, including gap assessments, root-cause analysis, action plans, and remediation tracking to closure. 

  • Support governance and reporting processes, preparing stakeholder communications for senior leadership and audit committees as needed. 

What you need to have: 

  • Bachelor’s degree in accounting, finance, business, or related field; advanced degree or professional certification (CPA, CIA, CISA, or equivalent) preferred. 

  • 6–10+ years’ experience in internal controls, risk management, internal/external audit, or regulatory compliance within a global or multi-jurisdictional environment. 

  • Strong knowledge of European regulatory frameworks and requirements (examples: IDD, AML, DORA, SOX, GDPR — as applicable). 

  • Proven experience working with Internal Audit and/or Big Four external audit firms and managing audit engagements, documentation, and stakeholder communications. 

  • Fluent in German and English, with excellent written and verbal communication skills. 

What makes you stand out: 

  • Hands-on experience partnering with Technology and Compliance teams to design, implement, and test controls (including IT/technology controls). 

  • Professional certifications (CPA, CIA, CISA) and/or advanced degree that demonstrate technical depth. 

  • Prior experience translating regulatory and audit requirements into operationally-feasible solutions across multiple countries or business lines. 

  • Strong project management skills and a pragmatic, solutions-oriented mindset balancing risk mitigation, audit expectations, and business objectives. 

  • Track record of driving continuous process improvements to increase control efficiency and effectiveness. 

 

Why join our team: 

  • We help you be your best through professional development opportunities, interesting work and supportive leaders 

  • We foster a vibrant and inclusive culture where you can work with talented colleagues to create new solutions and have impact for colleagues, clients and communities.
