Senior Pipe Stress Engineer

About the role

Audubon is seeking a Senior Pipe Stress Engineer to join our team in Houston, TX. This role leads the analysis, design verification, and optimization of complex piping systems to ensure structural integrity, code compliance, operability, and safe performance under all operating, thermal, transportation, and environmental conditions. The Senior Pipe Stress Engineer provides technical leadership and coordination across piping, structural, mechanical, civil, process, and vendor disciplines throughout all phases of EPC project execution, serves as a subject matter expert, supports project execution strategy, mentors junior engineers, and ensures quality and consistency of stress analysis deliverables.

Responsibilities

• Lead and perform advanced pipe stress analysis using software such as CAESAR II or equivalent.
• Evaluate piping systems for thermal expansion and contraction, sustained, operating, occasional, and fatigue loads, wind, seismic, wave, blast, transportation, and slug flow loads, pressure, weight, vibration, and dynamic effects.
• Verify compliance with applicable codes and standards including ASME B31.3, B31.1, B31.4, B31.8, ASCE 7, MSS-SP standards, API standards, and client/project-specific specifications.
• Develop, review, and approve stress analysis models, stress isometrics, pipe support and restraint designs, load calculations, flexibility studies, nozzle load evaluations, and dynamic analysis reports.
• Coordinate closely with piping design teams to improve routing flexibility and support schemes, structural and civil teams regarding pipe rack, sleeper, and foundation loading, and mechanical/equipment vendors to validate allowable nozzle loads and equipment interface requirements.
• Lead pipe stress reviews during model reviews, 30/60/90% design reviews, HAZOP reviews, and constructability/operability reviews.
• Request, review, and validate vendor allowable loads and ensure compliance with equipment limitations.
• Prepare and issue pipe stress calculation packages, pipe support load summaries, equipment nozzle load tables, pipe rack and structural load reports, support sketches, and restraint details.
• Review and approve third-party and vendor stress calculations when required.
• Support project execution during FEED, detailed engineering, IFC development, fabrication, construction, pre-commissioning, site modifications, and reroutes.
• Review and resolve RFIs, field change requests, non-conformance reports, and stress-related construction issues.
• Perform re-analysis for site changes, transportation, and lifting scenarios.
• Assist with project staffing forecasts, schedule development, and interdisciplinary coordination.
• Support continuous improvement initiatives, engineering standards development, and lessons learned implementation.

This position requires the candidate to be in the client office 5 days a week.

Requirements

• Bachelor’s Degree in Engineering (ABET-accredited institution preferred).
• Professional Engineer (PE) license preferred.
• LNG project experience strongly preferred.
• Experience with offshore or modularized facilities preferred.

Skills

• CAESAR II (including dynamic analysis modules).
• Finite element analysis concepts.
• 3D model review platforms.
• Change request/order management.
• Design verification and dynamic analysis.
• Engineering Procurement and Construction (EPC/EPCC/EPCM).
• HAZOP (Hazard and Operability Analysis).
• Project execution and schedule development.
• Standards development and stress engineering.
• Technical leadership and problem-solving.
