Leadership Built on Service

Sigmatech's leadership team brings together decades of military service, DoD program management, and industry expertise — program officers, commanders, and technical leads who have sat on both sides of the table and understand what the warfighter actually needs.

Today that experience guides a workforce of 586+ teammates across five offices nationwide — 57% veterans and 85% holding security clearances — supporting missions across space, air, and ground domains.

Built on Service

Our growth has been earned program by program — 50+ prime contracts delivered by teams who have sat on both sides of the acquisition table.

A Culture That Stays

Decades of customer retention and a cleared, veteran-heavy workforce reflect a simple truth: people stay where the work matters and the leadership leads from the front.
