Role Overview

The Administrative Assistant keeps the business side of the laboratory running. This role owns customer invoicing, purchasing, and day to day office administration, and is the first point of contact for customers calling or emailing the lab.

It is a hands-on, execution-focused role. Work is measured on accuracy and follow-through: invoices that go out correctly and on time, purchase orders that land with the right vendor at the right price, records that stand up to an audit, and customers who get a clear answer quickly. The Administrative Assistant works closely with lab staff, the Office Operations Manager, and SSA's shared finance team.
