Jobs at Zachry Nuclear Engineering, Inc.

Lead mechanical engineering efforts for power, energy, and chemical projects including equipment specification and vendor review, piping and equipment calculations, field surveys, project scheduling/budgeting, staff supervision and mentoring, and ensuring compliance with safety and environmental design criteria.

Lead electrical design and execution for power/industrial projects: develop schematics, one-line/three-line diagrams, lighting, grounding, and raceway systems; coordinate disciplines, manage budgets and schedules, provide field support/commissioning, and ensure compliance with codes and standards.

Support project managers by developing and maintaining engineering and integrated project schedules, monitoring progress, preparing earned value reports and forecasts, analyzing schedule impacts, and coordinating cost control and reporting for engineering projects.

Perform piping stress and flexibility analyses (ASME B31.1/B31.3) using CAESAR II; specify and evaluate engineered supports and nozzle loads; prepare stress reports; perform field surveys; coordinate with designers, vendors, and clients; manage schedules, budgets, and provide project status reporting.

Perform mechanical engineering tasks for EPC projects: specify and review vendor documents for pressure vessels, pumps, tanks, and heat exchangers; perform equipment and piping calculations; specify piping materials; conduct field surveys; attend project meetings; and potentially lead mechanical scope including schedule, budget, and reporting.

Design and analyze chemical process systems: produce PFDs, P&IDs, heat and material balances, process simulations, and equipment datasheets. Size and rate pumps, vessels, exchangers, and relief systems; perform hydraulic and flare header analysis. Prepare instrument and line lists, process descriptions, and participate in HAZID/HAZOP reviews. Support projects as an individual contributor and present technical information to clients and peers.

Lead process engineering team to develop PFDs and P&IDs, size and rate equipment, perform hydraulic and relief/flare analyses, participate in HAZOP/LOPA and PHA reviews, ensure regulatory compliance, mentor junior engineers, estimate project resources, and present technical information to clients and peers.

Lead project controls for engineering projects: develop, maintain, and monitor Primavera P6 schedules; integrate engineering, procurement, and construction timelines; produce earned value and progress reports; forecast resources and budgets; advise management on impacts and corrective actions; train junior planners.

Design and develop detailed electrical systems and 3D models for industrial and power projects using AVEVA E3D/PDMS. Produce drawings, perform clash detection, coordinate multidisciplinary design, generate BOMs, review vendor data, and ensure compliance with project specifications and industry standards.

Lead development and management of Installation Work Packages (IWPs) to ensure safe, efficient field execution. Break down CWPs into IWPs, coordinate with superintendents, engineering, procurement and safety, support schedule updates, material tracking, 4D modeling, and validate progress through field walks and reporting. Drive AWP processes, resolve constraints, and support continuous improvement and change management.

Lead electrical design and execution for industrial/process projects. Create schematics, one-/three-line diagrams, lighting, grounding, and raceway designs; coordinate disciplines; support field verification, construction, commissioning, budgeting, and client meetings.

Lead engineering for utility-scale combined cycle power plant EPC projects from award through commissioning. Provide technical governance, manage multidisciplinary global engineering teams, oversee power island, BOP, electrical, I&C, civil/structural systems, support procurement, construction, commissioning, risk management, and engineering budgets to ensure schedule, cost, quality, and successful plant operation.

Lead electrical engineering design and execution for power/energy projects. Manage teams, perform complex electrical calculations and studies, review and seal engineering documents, coordinate procurement and vendor deliverables, provide field and construction support, mentor junior staff, and ensure quality and budget compliance across medium- and high-voltage systems.

Lead mechanical engineering for EPC power projects: manage technical design, schedules, budgets, equipment specifications and vendor evaluations; perform field walkdowns, mentor staff, prepare RFQs and proposals, and seal engineering deliverables as a licensed Professional Engineer.

Lead and supervise electrical engineering teams for oil & gas and petrochemical projects. Independently perform design, studies, specifications, equipment procurement, review vendor deliverables, mentor staff, ensure QA, and provide field/construction support.

Lead full lifecycle delivery of large combined-cycle power projects from FEED through commissioning and startup. Own scope, schedule, budget, quality, and safety; direct multi-discipline teams, manage project controls, change management, vendor oversight, client relationships, and team development. Support field activities and travel as needed.

Lead instrumentation and controls design deliverables (instrument index, DCS/PLC and CEMS datasheets, I/O lists, process control narratives). Perform specifications, estimates, vendor evaluation, and technical problem solving. Supervise/mentor junior staff, maintain up-to-date I&C practices, and support field and office work using CAD and engineering software.

Provide document control and administrative support for engineering projects: manage, log, review, and distribute documents; enforce naming/revision standards; track project assignments; communicate with clients/vendors; maintain EDMS and Microsoft Office files; assist with meeting preparation and general office equipment tasks.

Entry-level Mechanical Engineer supporting a Senior Mechanical Engineer on process equipment projects. Duties include specifying and reviewing vendor documents and bids for pressure vessels, tanks, pumps, and heat exchangers; performing equipment and piping calculations; specifying materials for piping services; attending client/vendor/internal meetings; and conducting field surveys to collect data and interpret drawings and specifications.

Develop PFDs and P&IDs; perform heat and material balances, hydraulic and relief system analyses; size and rate pumps, vessels, exchangers; support HAZOP/LOPA; ensure safety and regulatory compliance; estimate and track budgets; present technical information and may supervise a small engineering team.
