About Zistos Corporation

For over two decades, Zistos Corporation has been designing and manufacturing advanced portable visual inspection systems — proudly engineered and assembled in the USA.

Our technology helps industrial, tactical, rescue, and security professionals around the world “see the unseen” — from inspecting tanks and confined spaces to supporting SWAT and urban search & rescue missions.

Now, we’re looking for a hands-on Administrative Assistant to join our team and play a vital role at the heart of our operations.

About the Role

This is not your typical administrative job. It’s a high-impact, cross-functional role where you’ll collaborate with leadership across Accounting, HR, and Operations — ensuring accuracy, organization, and efficiency in the processes that keep our company running.

You’ll handle accounts payable and receivable, payroll, HR administration, vendor relations, and office coordination, helping us maintain the precision and excellence that define Zistos.

If you’re dependable, detail-oriented, and thrive in a fast-paced manufacturing environment, we want to meet you.

What You’ll Do

Manage AP/AR and financial records in SAP.
Process payroll via ADP and maintain employee documentation.
Coordinate insurance renewals, benefits, and HR compliance.
Support trade show logistics, purchasing, and vendor relationships.
Drive organization and structure across departments.

What You Bring

8–10 years of experience in administrative, accounting, or HR roles.
Strong bookkeeping and payroll knowledge (ADP required, SAP preferred).
Excellent organization, communication, and follow-up skills.
Integrity handling confidential information.
A proactive mindset — you see what needs to be done and make it happen.

Why Zistos?

At Zistos, you’ll join a small, dedicated team where your work truly matters. You’ll help sustain a legacy of innovation, craftsmanship, and reliability — backed by the stability and shared services of EquityX, a U.S. private investment group supporting Zistos’ next phase of growth.
