Aviation and Aerospace Component Manufacturing Los Osos, CA 201–500 employees Founded 1971 Privately Held

Rantec designs and manufactures power conversion systems for military and aerospace contractors. The hiring mix is heavily weighted toward engineering (21 roles) with acute junior-level demand, paired with aggressive modernization efforts across tooling and infrastructure—SharePoint file-share redesign, network refresh, and ERP system upgrades suggest internal operations are being rebuilt while the core business scales. Obsolescence and supplier quality compliance appear as recurring pain points, typical for defense suppliers operating under AS9100 and customer-driven qualification requirements.
