Project Manager Assistant

About The Job

We’re looking for a reliable and detail-oriented Project Manager Assistant to support our San Antonio project management team. This role is ideal for someone who enjoys structured, office-based work and is seeking a long-term administrative career in the construction industry — rather than a stepping stone to a Project Manager role.

As a Project Manager Assistant, you’ll be a key organizational backbone for our projects, ensuring documentation, communication, and administrative processes run smoothly. You’ll work closely with Project Managers, Assistant Project Managers, and field teams to keep projects organized, compliant, and moving forward.

At Jamail & Smith, our project teams rely on strong administrative support to deliver exceptional results for our clients. The Project Manager Assistant plays a vital behind-the-scenes role, helping our teams stay organized, responsive, and efficient. If you take pride in keeping things running smoothly and supporting others’ success, you’ll fit right in.

This is a long-term administrative opportunity for someone who values consistency, organization, and collaboration. Unlike an Assistant Project Manager position, this role is not designed as a training path to become a Project Manager. Instead, it’s a stable, essential support role for individuals who enjoy administrative work and want to grow their expertise in project coordination and construction operations over time.

Since 1982, Jamail & Smith has delivered over 9,600 projects on time and on budget for more than 80 public entities. We specialize in Job Order Contracting (JOC) and CSP Construction Services, and we’re known for our commitment to service, innovation, and quality. Our success is built on strong teams — including the administrative professionals who support every project.
