Job SummarySMSI is seeking a full-time Senior Project Engineer to work onsite with our client, Los Alamos National Laboratory (LANL) to lead / accomplish engineering efforts. The qualified candidate will 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.
ResponsibilitiesInfrastructure & Security Design Management- 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.
On-Site Construction & Commercial Support- Manage technical document control, submittals, and RFIs directly from the job site using Project Sight 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.
Required Skills/ Abilities- 10+ years of project engineering experience, specifically focused on commercial infrastructure, civil works, or high-security/government-adjacent facilities.
- Demonstrated experience leading work through design, field execution, turnover, and closeout in a high-consequence, security-sensitive, or nuclear-facility environment is preferred.
- Hands-on, proficient experience with Project Sight or equivalent (project management), Delta (cost/financial tracking), Aproove or equivalent (proofing/design review), and Microsoft Office Suite.
- Willingness and capability to work 100% on-site at LANL's designated project locations.
- Exceptional attention to detail regarding physical layout compliance, strict document control, and clear communication under tight project deadlines.
- Proven ability to make sound technical decisions; coordinate diverse stakeholders; manage technical risk; and communicate clear, timely engineering direction.
- Ability to obtain and maintain a DOE Q clearance is required.
- US citizenship is required.
- An active Real-ID driver's license is required.
Education- Bachelor's degree in Civil Engineering, Mechanical Engineering, Electrical Engineering, or a related discipline; or, an equivalent combination of education and experience directly related to the occupation.
