Location: Pennsylvania
Compensation: $110,000 - $140,000 / year
Description
Client: Confidential Commercial Interiors Contractor
Location: Chester / Newtown Square, PA area

Compensation: $110,000-$130,000 base, with flexibility up to $140,000 for an exceptional fit
A long-established commercial interiors contractor in the Chester / Newtown Square, PA area is seeking a hands-on Project Manager / Estimator to support continued growth and take ownership of projects from estimate through closeout.
This is a high-trust role for someone who can operate across both estimating and project management. The right person will be able to prepare bids, manage execution, coordinate vendors and subcontractors, stay on top of project documentation, and help reduce the day-to-day operational load on ownership.
This is not a layered corporate PM role, and it is not a pure estimating seat. The company needs a practical, steady, low-ego commercial interiors professional who can step into responsibility, manage multiple moving pieces, and become a reliable right-hand operator for the business.
Manage commercial interiors projects from estimating and bidding through execution and closeout.
Prepare estimates, takeoffs, budgets, bid packages, and related project documentation.
Coordinate subcontractors, vendors, field teams, materials, schedules, client communication, and project follow-through.
Attend job meetings, walkthroughs, and local site visits as needed.
Help maintain control of budgets, timelines, scope, and closeout requirements.
Communicate clearly with ownership, clients, internal team members, and field partners.
Support increased bid capacity and project execution so ownership can step back from some day-to-day project load.
The strongest fit will have current or recent experience in commercial interiors construction, especially within scopes such as:

• Drywall
• Framing
• Ceilings
• Acoustical systems
• Wall systems
• Interior systems
• Tenant improvement
• Fit-out

Candidates should have real experience across both estimating and project management. The client is looking for someone who has owned work from bid through completion, not someone who has only supported one narrow part of the process.
Current or recent commercial interiors construction experience.
Hands-on project management and estimating experience.
Ability to run jobs end to end, from estimate/bid through execution and closeout.
Experience managing multiple projects, schedules, vendors, subcontractors, and client expectations.
Strong communication, organization, ownership, and follow-through.
Comfort working in a small, owner-led environment.
Ability to work fully onsite in the Chester / Newtown Square, PA area.
Experience with BuzzBid, Bluebeam, PlanSwift, STACK, OST, Procore, digital takeoff tools, or similar platforms.
Background with a lean specialty contractor or small-to-mid-sized commercial interiors company.
Direct walls-and-ceilings experience.
Experience working closely with ownership or serving in a right-hand operational role.
Stable career history within commercial interiors or closely adjacent interior construction scopes.
This role is likely not the right match for candidates coming primarily from:

• Landscaping
• Plumbing
• HVAC
• Residential-only construction
• Pure superintendent roles
• Pure estimating without execution ownership
• Pure project management without estimating involvement
• Large, highly layered corporate environments with little hands-on responsibility

This position is designed to create real operational leverage for the owner. The company needs someone who can take pressure off leadership, increase project and bid capacity, and help support growth while maintaining quality, communication, and accountability.
For the right candidate, this is a strong opportunity to step into meaningful responsibility, work directly with ownership, and become a key part of a stable commercial interiors business.
