Assistant Project Manager Civil Engineer Jobs in Missouri

Why This Role Exists

This is not a typical Project Manager hire. We are building the next layer of leadership at VonArx Engineering. As we scale, our President/Principal Engineer needs a trusted right-hand- someone who can lead the engineering team day-to-day and own project delivery. If you want to help build something, not just work inside it, this is the opportunity.

Position Summary

The Senior Project Manager serves as the operational and technical lead for VonArx Engineering's engineering staff and project portfolio. Reporting directly to the CEO and President/Principal Engineer, this person oversees all project delivery and mentors and develops the engineering team.

Who Thrives Here

You have outgrown being purely technical and want to lead. You have managed projects and people, and you are ready to own outcomes at a higher level. You are energized by the idea of joining a firm at a pivotal growth stage where your decisions matter, your leadership shapes the culture, and your trajectory is genuinely tied to the firm's success. You do not need hand-holding; you do not wait to be told what to do, and you treat every project like your name is on it because, in this role, it will be.
