• A strong research mindset and careful attention to detail‑especially when validating documents, data, and banking information.

• Clear, professional communication skills and a customer‑service approach to working with internal teams and vendors.

• The ability to manage several priorities independently while remaining organized and responsive.

• A collaborative, team‑first mindset, along with the curiosity and adaptability to learn evolving processes and systems.
