Full job description
Opportunity to build a career in the Construction field
Position Overview
JGM is seeking a motivated early career professional with 0-3 years of experience to join our growing team, working in person out of our Downingtown, PA office. This is a career-building role, not a stepping stone - JGM is expanding, and we want to invest in someone who is looking to grow their career with us for the long haul.
The ideal candidate will have:
A construction management or engineering degree, or a construction-related trade/technical school program - paired with an internship or co-op with a general contractor, industrial contractor, or similar.
You do not need direct industrial experience to apply; general contracting or commercial construction backgrounds are welcome, provided your education and/or internship experience is construction related.
Your hands-on training will be via, "the JGM way," working directly alongside senior estimators to build real skills in structural steel fabrication, erection, equipment setting, and piping estimating. As your experience and judgment grow, so will your responsibility and opportunities - with a clear, defined path toward advancing into senior and eventually leadership-level estimating roles as JGM continues to grow.
Responsibilities
Assist in developing detailed cost estimates for industrial construction projects, from concept through final proposal, under the guidance of senior estimators.
Learn to analyze project documentation (drawings, specifications, RFIs) to identify scope, risks, and value engineering opportunities.
Perform quantity take-offs and pricing for structural steel fabrication, erection, equipment setting, and piping.
Support the solicitation, evaluation, and negotiation of subcontractor and vendor pricing across trades, including concrete/civil, electrical, and specialty subcontractors.
Collaborate with project management, engineering, and procurement teams to ensure accurate scoping and budgeting.
Help prepare comprehensive bid proposals, and, as skills develop, help present estimates to leadership and clients.
Contribute ideas on cost-saving measures and alternative solutions to meet client needs.
Build working knowledge of industry trends, material costs, and construction best practices.
Progress toward independently owning estimates and mentoring newer team members as tenure and skill grow.
Qualifications
0-3 years of experience in construction estimating, project engineering, or a related role - including relevant internship or co-op experience.
Associate or bachelor’s degree in construction management, civil/structural engineering, or a related field from a college, university, or trade/technical school.
Relevant internship or co-op experience with a general contractor, industrial contractor, or similar is strongly preferred.
Strong analytical, math, and organizational skills.
Some ability to read and interpret engineering drawings, specifications, and bid documents - or a strong aptitude and willingness to learn quickly.
Comfortable with Microsoft Office Suite;(Word, Excel, Outlook PowerPoint)
Clear, professional communication and a collaborative, coachable mindset.
Genuine interest in building a long-term career at JGM and growing into a senior estimating role over time.
Willingness to travel to job sites for site walk-throughs as needed
Preferences
Familiarity with estimating software (e.g., Bluebeam, Procore, Sage Estimating, or similar) is a plus - training will be provided.
Open to candidates from general contracting, commercial, or industrial backgrounds, provided their education and/or internship experience is construction related.
Growth and Career Path
JGM is a growing company, and we are building this role for the long term - not as a stepping stone. We want the person we hire to build and advance their career here at JGM.
Structured, hands-on training under senior estimators from day one - you will learn JGM estimating approach across structural steel, erection, equipment setting, and piping.
A defined progression from Estimator to Senior Estimator and beyond, with growing project scope and responsibility as your skills develop.
As JGM continues to expand, we are looking to grow our own future senior estimators and project leaders from within - this role is a starting point for that path.

When the project is complex, the schedule is fixed, and failure is not an option — industrial owners call JGM.
We are a turnkey self-perform industrial construction and fabrication partner built for Fortune 500 owners who need more than a contractor. They need a team that engages early, controls every critical scope, and delivers with certainty in the most demanding environments on earth.
What makes JGM different:
We self-perform everything. Steel erection, structural fabrication, process piping, OEM equipment setting, precision alignment, heavy rigging and hauling, metal siding and roofing — executed by our own skilled workforce of ironworkers, fitters, welders, millwrights, and boilermakers. Single-source accountability from first plan to final bolt.
Safety and quality aren’t managed on our projects — they’re engineered into them. From early engagement through closeout, our Falcon Flight Plan ensures every phase is planned, controlled, and executed with safety as the foundation.
We specialize in solving what others won’t take on:
▸ Active operating facilities and live plant environments
▸ Critical outages and scheduled shutdowns
▸ Heavy, complex, high-consequence installations
▸ Precision, tolerance-driven work with no margin for error
Backed by 25+ years of proven execution:
▸ ENR Top 600 Specialty Contractor — 2024 & 2025
▸ AISC Certified Fabricator (Structural Steel + Advanced Bridge + Fracture Critical Endorsement)
▸ AISC Certified Steel Erector
▸ ASME “S” & “R” Stamps
Founded in 2001 by Joseph Messner Jr. — fifth-generation steel and industrial construction — JGM has grown from a garage startup to a nationally trusted partner for owners in Mining & Minerals, Metals, and Power.
We don’t just build facilities. We build confidence.
WE CAN. WE WILL. WE DO.
