Junior Project Manager - Construction (Windows and Doors) About the Role

Cornerstone is combining its estimating and project management departments and is hiring a Junior Project Manager to support impact window and door projects. This role begins with estimating responsibilities, with an intended path into project management as the combined department develops.

Success in this position means producing accurate, plan-aligned estimates by carefully reviewing construction documents, identifying required materials and configurations, and documenting assumptions clearly. The transition from estimating to project management will depend on readiness and department needs, with no fixed promotion timetable.

• Review architectural plans, schedules, specifications, and related project documents to understand required scope.
• Identify and document all windows, doors, openings, configurations, finishes, glass requirements, and other elements needed to price the project.
• Determine appropriate products for each project based on design requirements, building conditions, code requirements, and customer needs.
• Follow specified manufacturers and products when they are called out in the plans or project documents.
• Identify missing, unclear, or conflicting information that may require clarification before pricing.
• Obtain, organize, and prepare information needed to request vendor or manufacturer pricing when required.
• Prepare complete, accurate project estimates, including appropriate products, options, quantities, and pricing.
• Verify completed estimates for accuracy and ensure alignment with the plans and requested scope of work.
• Document assumptions, exclusions, alternates, and recommended upgrades clearly and consistently.
• Finalize estimates and provide them to the appropriate salesperson, project manager, or team member for review and customer delivery.
• Support the combined team by maintaining organized project documentation and staying aligned with estimating and project management workflows.

• Education in construction management, engineering, architecture, or a related field (or equivalent practical experience).
• 2+ years of experience in estimating, construction documentation review, or a related role (entry-level candidates are welcome).
• CAD software experience is preferred, or a willingness to learn CAD software.
• Ability to review architectural plans, schedules, and specifications with accuracy and consistency.
• Strong attention to detail and the ability to translate construction documents into accurate pricing inputs.
• Working knowledge of windows and doors concepts, including common configurations, finishes, and glass requirements.
• Comfort working with product specifications, requirements, and manufacturer callouts.
• Ability to identify gaps or inconsistencies in documentation and raise questions early.
• Clear, professional communication skills for documenting assumptions and coordinating information within the team.
• Organizational skills to manage estimate inputs, quantities, options, and pricing details.

• Health insurance options (medical, dental, and vision)
• Paid time off (PTO) and paid holidays
• 401K match
• Weekly lunch stipend
