This role is well‑suited for professionals seeking to deepen audit judgment, gain broad business exposure, and build a foundation for future growth within Internal Audit or the life sciences industry.

• Participate in special projects and continuous improvement initiatives (e.g., templates, automation, analytics use cases) that enhance audit efficiency and consistency
• Provide informal guidance to less experienced staff (e.g., walkthrough support, testing approach, documentation quality) and **escalate risks/issues to Audit Management** in a timely manner

Who You Are

You are a critical thinker with the ability to understand business processes and articulate risks clearly and practically. You thrive in a dynamic environment, learning through hands‑on audit experience. Your curiosity, adaptability, and self‑motivation drive you to expand your technical and business knowledge. You collaborate effectively with audit team members and business stakeholders, fostering strong professional relationships.
