About The Position

Longenecker & Associates (L&A), a Geosyntec Company, is seeking a Senior Project Engineer to support work at Los Alamos National Lab in Los Alamos, New Mexico. This is an on-site role leading engineering efforts for large-scale infrastructure and security-oriented projects. The engineer serves as the primary technical liaison among project management, multidisciplinary design teams, physical security engineers, construction management, and other stakeholders, with accountability for assigned scope throughout the engineering lifecycle—from project definition and design development through construction, commissioning, turnover, and closeout. The position supervises and directs engineering assignments across disciplines or designated project portions. It coordinates civil, structural, architectural, mechanical, electrical, fire protection, network, security, and facility-system interfaces; supports constructability and design reviews; manages technical changes and project documentation; tracks cost and schedule; and verifies quality, code compliance, safety interfaces, configuration management, and security requirements. The engineer also identifies and resolves technical and interface risks, mentors junior engineers, and supports compliant project turnover and records completion.

Requirements

At least 10 years of project engineering experience focused on commercial infrastructure, civil works, or high-security/government-adjacent facilities, or an equivalent combination of education and experience.
Hands-on proficiency with ProjectSight or equivalent project-management software, Delta or equivalent cost/financial tracking software, Aproove or equivalent proofing/design-review software, and Microsoft Office.
Exceptional attention to detail regarding physical-layout compliance, strict document control, and clear communication under tight deadlines.
Ability to make sound technical decisions, coordinate diverse stakeholders, manage technical risk, and communicate clear and timely engineering direction.
U.S. citizenship, due to federal contract security requirements.
Ability to pass a federal background investigation to secure and maintain DOE Q security clearance.
Bachelor’s degree in Civil Engineering, Mechanical Engineering, Electrical Engineering, or a related discipline, or equivalent experience.
Specialized coursework in relevant general engineering, architectural design, or an appropriate engineering discipline, and progressive work experience including supervision; experience in project design engineering is preferred within this qualification description.
Willingness and capability to work 100% on-site at designated project locations.
Compliance with federal contractor drug-free workplace requirements; employees working under federal contracts may be subject to federal restrictions prohibiting marijuana use regardless of state law.

Nice To Haves

Experience leading work through design, field execution, turnover, and closeout in a high-consequence, security-sensitive, or nuclear-facility environment.
Project design engineering experience; relevant experience may also include startup, field engineering, or plant operation in large industrial plants, utilities, process plants, or engineering/construction firms.

Responsibilities

Lead and accomplish engineering efforts for assigned project scope, from project definition and design development through construction, commissioning, turnover, and closeout.
Supervise and direct engineering activities and assignments across disciplines or designated portions of a project.
Coordinate interfaces among security and infrastructure designs, including MEP, structural, network, and physical/electronic security subsystems.
Manage collaborative proofing and review of construction drawings, schematics, security layouts, structures, communications, and site work using Aproove or an equivalent tool.
Conduct constructability reviews addressing high-security requirements, physical barriers, access-control layouts, and critical utility routing.
Develop efficient engineering solutions that preserve infrastructure longevity and security requirements while meeting budgets and contract requirements.
Serve as the accountable engineering point of contact for assigned scope and integrate technical decisions across the project.
Coordinate engineering with designers of record, construction subcontractors, facility operations, safety, security, quality, and other 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 from the job site using ProjectSight or an equivalent system.
Perform cost engineering and progress tracking using Delta or an equivalent tool, evaluate subcontractor change orders, manage cost projections, and maintain commercial compliance.
Resolve complex field conflicts while ensuring infrastructure changes preserve security design intent.
Track critical scheduling milestones using Microsoft Office tools and optimize sequencing for high-security component handoffs and site testing.
Enforce quality-control metrics and conduct routine field inspections to verify installations meet structural specifications and security classifications.
Mentor and guide junior engineers on-site 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 resolution paths; and escalate matters requiring management or stakeholder decisions.
Maintain visibility of engineering deliverables, reviews, approvals, commitments, and critical-path actions supporting construction and major milestones.
Support commissioning, turnover, closeout, and records completion for a compliant transition of completed work to the customer.
Complete required health and safety training, medical monitoring, and client-driven drug and background testing.
