Assistant Project Manager

Founded in 1981 and headquartered in Irvine, CA, Professional Diversified Flooring (PDF) is a leading commercial flooring contractor serving End-Users, General Contractors, Real Estate firms across Los Angeles, Orange County, San Diego, Las Vegas, and Phoenix. With a portfolio spanning corporate offices, healthcare, hospitality, and large-scale institutional projects, PDF partners with some of the most respected General Contractors in the Western U.S.

PDF is growing fast. We have evolved from a traditional commercial flooring contractor into a technology-forward construction company — and we need detail-driven project professionals to help us scale.

The Assistant Project Manager sits at the execution core of our business, embedded directly in an active project portfolio and responsible for keeping complex, multi-phase commercial flooring projects moving accurately and on time.

This is not a clerical role. This is a foundational PM role with real responsibility, direct exposure to senior leadership, and a defined runway into full Project Management and beyond. High performers here move up.

PDF is in an early stage of hypergrowth — modernizing our operations, scaling our team, and investing in proprietary technology to lead our industry. If you want to grow inside a company as it transforms, and be developed by some of the best leaders in commercial construction, this is your moment.

The Assistant Project Manager provides critical, end-to-end support across an assigned PM portfolio — from pre-construction coordination and submittal management through field documentation, financial tracking, and project closeout. You will work directly alongside a Project Manager, Senior PM, or Project Executive, learning the full commercial construction lifecycle while owning key operational responsibilities from day one.

You report to a Project Manager, Senior Project Manager, or Project Executive, or General Manager — with real visibility to senior leadership and meaningful opportunities to expand your scope as you demonstrate your capabilities. The best performers in this seat have a clear, supported path into independent Project Management.
