Essential Duties and Responsibilities

We are seeking a highly skilled, on-site Senior Project Engineer to lead / accomplish engineering effort.

• Possess critical skills of design management and construction support for large-scale infrastructure and security-oriented projects.
• In this role, you will be the technical backbone of our physical security installations and infrastructure deployments, ensuring complex designs are translated flawlessly into hardened, high-performing facilities.
• Operating strictly on-site, you will serve as the primary technical liaison between project management, multidisciplinary design teams, physical security engineers, and interface with construction management to deliver mission-critical projects on schedule and within budget.
• The role carries accountability for the full engineering lifecycle of assigned scope from project definition and design development through construction, commissioning, turnover, and closeout.
• Supervises the engineering activity (all disciplines) on a project, or designated portions of a project, for a global business unit.
• Plans and directs engineering assignments on the project.
• Demonstrates technical responsibilities for interpreting, organizing, executing, and coordinating these assignments.
• Coordinate security and infrastructure design interfaces, aligning MEP, structural, network architectures, and specialized physical/electronic security sub-systems.
• Utilize Aproove to manage collaborative online proofing, ensuring all security layout, structures, communication, site work and other associated construction drawings, schematics, and design iterations undergo rigorous review and approval.
• Conduct strict constructability reviews targeting high-security requirements, physical barriers, access control layouts, and critical utility pathing.
• Drive efficient engineering solutions that optimize infrastructure longevity and physical security profiles without compromising project budgets or contract compliance.
• Lead combined Project Engineer and Field Engineer functions, Serve as the accountable engineering point of contact for assigned scope, maintaining the technical path forward and integrating decisions across the project.
• Integrate multidisciplinary design work across civil, structural, architectural, mechanical, electrical, fire protection, network, security, and facility-system interfaces.
• Lead engineering coordination with designers of record, construction subcontractors, facility operations, safety, security, quality, and other project stakeholders.
• Manage engineering changes and technical-resolution processes, including Field Change Requests, Design Revision Notices, Requests for Information, nonconformance dispositions, design clarifications, constructability reviews, and field-change evaluations.
• Manage technical document control, submittals, and RFIs directly from the job site using ProjectSight to maintain a single, real-time source of truth.
• Perform cost engineering and progress tracking via Delta, evaluating subcontractor change orders, managing cost projections, and maintaining strict commercial compliance.
• Provide technical resolution for complex field conflicts, ensuring that changes to infrastructure do not breach security design intent.
• Track critical scheduling milestones using Microsoft Office tools, optimizing sequencing for high-security component handoffs and site testing.
• Enforce comprehensive quality control metrics, conducting routine field inspections to verify that installations meet infrastructure structural specs and security classifications.
• Mentor and provide guidance to junior engineers on-site, fostering technical mastery in infrastructure delivery and security compliance.
• Evaluate design outputs and construction activities for code compliance, quality requirements, configuration management, safety interfaces, security impacts, and applicable engineering procedures.
• Identify technical, schedule, construction, and interface risks; develop practical resolution paths; and elevate matters requiring management or stakeholder decisions.
• Maintain project-level visibility of engineering deliverables, reviews, approvals, commitments, and critical-path actions supporting construction execution and major milestones.
• Support commissioning, turnover, closeout, and records completion to achieve a compliant transition of completed work to the customer.

Education and Licensure

• Bachelor’s degree in Civil Engineering, Mechanical Engineering, Electrical Engineering, or a related discipline / equivalent experience.
• Specialized courses in relevant general engineering, architectural design or an appropriate engineering discipline, and progressive work experience, including supervision, preferably in project design engineering; may include other relevant types of engineering including startup, field engineering or plant operation in large industrial plants, utilities, process plants or engineering/construction firms.
