About the Role

We’re partnered with a well-established, locally rooted construction organization that supports heavy civil and roadway projects throughout Southern Idaho. This team operates at the intersection of construction services and specialty subcontracting, working closely with general contractors and public entities to help projects run safely, efficiently, and on schedule.

Due to continued growth, they’re adding an Assistant Project Manager to support multiple active projects and develop into a full Project Manager over time. This is an excellent opportunity for a Project Coordinator or early-career construction professional who wants hands-on exposure, strong mentorship, and a long-term career path.

What Success Looks Like in This Role

Strong attention to detail in billing, quantities, and reconciliations

Proactive communication, issues are surfaced early, not after work is complete

Organized project tracking across multiple jobs at once

What We’re Looking For

Experience in the commercial or construction industry (GC or subcontractor background both welcome)

A Project Coordinator or Junior PM ready to step up and grow

Comfortable holding your ground, asking questions, and communicating clearly

Bachelor’s degree not required

Strong culture fit and interest in long-term growth (this team values stability and commitment)

Nice to Have:
