Build Your Future with MBG

Here, your voice is heard, your contributions matter, and your work helps shape meaningful projects and lasting relationships. If you're looking for a career built on trust, opportunity, and purpose, you'll find it at MBG.

MBG is growing and looking for Project Engineers who are ready to learn the business, support strong field execution, and build a foundation for long-term growth in construction management. Our Project Engineers bring curiosity, organization, and follow-through to every job-helping teams stay aligned, documentation stay clean, and projects move forward with confidence.

This role is based out of St. Louis. You'll gain hands-on exposure to ground up construction across multifamily, hospitality, senior living, and student housing while working closely with experienced Project Managers and Superintendents.

WHAT YOU WILL OWN

Project Engineers support the coordination and execution rhythm of assigned projects. You're accountable for helping keep documentation, information flow, and project controls aligned-ensuring the right details are captured, shared, and tracked so teams can make informed decisions and remove obstacles early.

Safety, Risk, & Quality Support

• Reinforce field safety expectations and reporting standards.

• Help identify and communicate risks early through documentation and coordination.

• Support quality tracking and issue documentation.

Scope, Documentation, & Project Controls

• Maintain a working understanding of drawings, specifications, and project scope.

• Prepare, review, and distribute RFIs and submittals through Procore.

• Maintain job files, as-builts, meeting minutes, and document control.

• Upload and organize daily and weekly jobsite photos.

Procurement, Logistics, & Coordination

• Track material approvals, deliveries, and procurement logs.

• Inspect and verify material deliveries.

• Assist with site logistics, badging, and coordination as assigned.

• Support Superintendent teams with punch list tracking and follow-up.

Financial & Project Support

• Assist with quantity verification and cost tracking inputs.

• Help prepare job progress reports.

• Support change documentation and closeout tracking.

Closeout & Handover

• Support punch, O&M documentation, warranties, and training coordination.

• Help drive organized, timely project closeout.

HOW THIS ROLE WORKS WITH LEADERSHIP

Project Engineers partner closely with Project Managers, Superintendents, and field teams to keep projects organized and moving forward. You'll be trusted to manage details, communicate clearly, and raise issues early, bringing questions, observations, and solutions to the team.

Regular interaction is focused on:

• Documentation health (RFIs, submittals, as-builts, meeting minutes).

• Procurement and material tracking.

• Field coordination and logistics support.

• Clearing blockers through accurate information and timely follow-through.

This role is highly collaborative and provides direct exposure to how MBG plans, builds, and delivers projects.

EXPERIENCE EXPECTATIONS

This role is a strong fit for candidates with 2-4 years of construction experience who want to build a career in project management. A related degree is preferred, and an equivalent combination of education and experience will be considered.

You should be comfortable:

• Reading and interpreting construction documents.

• Writing clear correspondence and meeting notes.

• Communicating effectively with field teams, trade partners, and internal stakeholders.

Familiarity with Procore and Microsoft Office (Excel, Word, Outlook) is expected. Microsoft Project experience is a plus. Hospitality and/or Multi-family project experience is helpful but not required.

Because this is a safety sensitive role with regular jobsite time, candidates should be able to work effectively in active construction environments. OSHA 30hour and First Aid/CPR/AED are preferred (or willingness to obtain).

WHAT SUCCESS LOOKS LIKE
