Job Description
ISTA Personnel Solutions is a dynamic and fast-growing BPO company. We are not a recruitment agency - we operate as a dedicated extension of our U.S.-based clients’ teams, delivering high-quality service with precision, efficiency, and a personal touch.
We are seeking a detail-oriented Executive Assistant with advanced Excel skills and a strong understanding of financial and reporting data. This is a hands-on support role working closely with executive leadership, with a strong focus on maintaining, updating, and improving Excel-based reports and recurring financial information. The role involves working with data exported from systems such as QuickBooks Online, ensuring accuracy, structure, and consistency across reporting files.
This position is best suited to candidates who enjoy structured work, spreadsheets, and detail-driven tasks rather than strategic finance responsibilities.

- Work Environment: This is a fully remote working role.
- You will be required to work on both South African and US public holidays (compensation for SA public holidays in accordance with the BCEA).
- Internet Requirements: A fixed fibre line with a minimum speed of 25 Mbps (upload & download) and the ability to support a wired Ethernet connection is mandatory. Applicants without a fixed fibre line cannot be considered.
