Construction Estimator Jobs in Puerto Rico (NOW HIRING)

About Solx

Solx is building the next generation of intelligent manufacturing. Our factory floor is where advanced hardware meets advanced software — and where AI at the edge directly drives yield, throughput, quality, and uptime. We are investing in the systems, infrastructure, and talent to make our operations the most intelligent in the industry — and we are building the manufacturing capacity to match that ambition.

About the Role

Be Solx's eyes, ears, and authority on the construction site. As Construction Manager, you are the owner's representative over the EPC and general contractor — the person on the ground who holds the physical build to the design, schedule, budget, quality, and safety we require. You will lead field superintendents and field QA/QC and make sure what gets built is what was drawn.

This is a hands-on, on-site role for a seasoned builder who has run large, complex projects and knows how to drive contractors without doing their job for them. You will coordinate across every trade — civil, structural, building, MEP, and equipment installation — and keep the work moving, safe, and in spec. You will report directly to the Project Manager.

Core Responsibilities

• Serve as the owner's representative on site, overseeing the EPC/general contractor and their subcontractors day to day.

• Lead field superintendents and field QA/QC to ensure work is built to drawings, specifications, and quality standards.

• Enforce the construction schedule and sequencing; monitor progress, surface delays early, and drive recovery plans.

• Review and validate contractor progress, pay applications, change orders, and RFIs in coordination with the Project Manager.

• Own field safety oversight; hold all contractors to the site safety program and stop work when conditions require it.

• Coordinate field execution across civil, structural, building, MEP, and equipment-installation trades.

• Manage inspections, materials testing, and commissioning readiness across trades.

• Track and document field conditions, deficiencies, punch lists, and as-built accuracy.

• Escalate risks, quality issues, and cost or schedule impacts to the Project Manager with clear options.

• Support systems turnover, closeout, and handover to commissioning and operations.

What You'll Work On

The scope of this role spans the day-to-day field execution of a high-tech manufacturing build-out, including: contractor oversight, field QA/QC, construction safety, schedule adherence, inter-trade coordination, inspections and testing, and commissioning readiness and closeout.

• Day-to-day oversight of the EPC/general contractor and trades across a large manufacturing build.

• Field quality control — verifying that installed work matches drawings, specifications, and standards.

• Construction safety on an active, multi-trade site.

• Schedule adherence, progress tracking, and recovery of slipping work.

• Inspections, testing, punch-out, and turnover to commissioning.

Required Qualifications

• 10+ years in construction management, including owner's-representative or general-contractor superintendent/CM roles on large, complex projects.

• Experience overseeing an EPC or general contractor on projects of $50M+.

• Deep field construction knowledge across civil, structural, and MEP scopes.

• Strong command of construction scheduling, QA/QC, and jobsite safety.

• Ability to read and enforce drawings and specifications and to manage RFIs, submittals, and punch lists.

• Bachelor's degree in Construction Management, Civil Engineering, or a related discipline — or equivalent field experience.

• Strong field presence and the ability to drive contractors to schedule, quality, and safety without micromanaging.

• Willingness to be based on-site in Puerto Rico for the duration of construction.

Preferred Qualifications

• Experience on industrial, advanced-manufacturing, cleanroom, or fab construction projects.

• OSHA 30 and/or PMP or equivalent certification.

• Experience delivering projects in Puerto Rico, the Caribbean, or other tropical, hurricane-exposed environments.

• Experience with equipment-installation and commissioning-readiness coordination.

• Bilingual English/Spanish.
