About this role
Secretary / Office Manager
Calc Engineering LLC | Doral, FL | Full-Time, On-Site (Mon–Fri, 8:00 AM – 5:00 PM)
Position Overview
Calc Engineering is seeking an organized, personable Secretary to support our growing team in Doral, FL. Serving as the backbone of daily office operations, this role combines traditional secretarial support—answering phones, managing correspondence, and providing front-desk coverage—with hands-on project, billing, and administrative support that keeps deliverables, documentation, invoicing, and client communications on track. Mornings center on keeping the office moving; afternoons shift toward the administrative work that ensures projects and paperwork stay on schedule.
This is an ideal opportunity for a candidate who is highly organized, discreet, and comfortable being the first point of contact for clients, vendors, and visitors in a fast-paced engineering environment. It is also a role with meaningful room to grow: a strong performer can advance into an Office Manager position over time, assuming broader operations, vendor, and project-support responsibilities.
