Process Mechanical Stress Engineer

Senior Mechanical Engineer / Stress Analysis Engineer

The Senior Mechanical Engineer / Stress Analysis Engineer is responsible for the engineering, analysis, and design of complex mechanical and piping systems supporting industrial and process facilities. This position serves as the technical authority for piping flexibility, stress analysis, equipment loading, and mechanical integrity while supporting multidisciplinary engineering teams through all phases of project execution.

Reporting to the Associate Principal Process Mechanical, this role provides advanced engineering expertise, mentors junior engineers, and ensures mechanical systems are designed in accordance with applicable codes, client standards, and industry best practices. The position plays a critical role in delivering safe, reliable, and constructible engineering solutions for industrial, manufacturing, pharmaceutical, food & beverage, life sciences, chemical, and advanced technology projects.

The specifics of the role include:

• Perform advanced piping flexibility and stress analyses using industry-standard software (e.g., CAESAR II or equivalent).
• Develop and validate piping stress models for thermal expansion, seismic loading, wind loading, pressure, dead weight, vibration, and occasional loads.
• Evaluate nozzle loads and equipment interface forces for pumps, compressors, heat exchangers, pressure vessels, tanks, and packaged equipment.
• Perform support design recommendations and evaluate pipe support requirements, restraints, anchors, guides, spring supports, and expansion joints.
• Analyze equipment foundations, structural interfaces, and piping interactions to minimize operational stresses.
• Develop engineering calculations and technical reports suitable for client review and Professional Engineer sealing where required.
• Review vendor equipment data to ensure compatibility with piping and mechanical system designs.
• Support mechanical equipment selection, specification, and installation requirements.

• Design industrial mechanical and piping systems supporting manufacturing and process facilities.
• Prepare engineering calculations, specifications, equipment data sheets, and design narratives.
• Review P&IDs, equipment layouts, piping arrangements, isometrics, and 3D models for mechanical integrity and constructability.
• Coordinate mechanical designs with structural, electrical, process, controls, architectural, and construction disciplines.
• Ensure compliance with client standards, project specifications, and applicable industry codes.

• Support projects from conceptual design through detailed engineering, construction support, startup, and commissioning.
• Produce high-quality engineering deliverables within established project schedules and budgets.
• Identify technical risks and develop practical engineering solutions.
• Participate in design reviews, HAZOPs, constructability reviews, and interdisciplinary coordination meetings.
• Provide engineering support during construction including RFIs, field inspections, engineering evaluations, and resolution of field issues.

• Serve as the department's subject matter expert for piping stress analysis and mechanical system integrity.
• Mentor junior mechanical engineers and designers in engineering principles, calculations, and code requirements.
• Review engineering calculations and deliverables prepared by other engineers.
• Assist in developing department engineering standards, calculation templates, and best practices.
• Support continuous improvement initiatives focused on quality, efficiency, and standardization.

• Participate in technical meetings with clients, vendors, and project stakeholders.
• Present engineering solutions and communicate complex technical information clearly.
• Support proposal development by providing engineering input, estimating effort, and defining technical scope.
• Assist with equipment procurement by reviewing vendor submittals and resolving technical issues.

Requirements:

• Bachelor of Science in Mechanical Engineering required.
• Professional Engineer (PE) license preferred.
• PE license required for positions responsible for sealing engineering calculations and design documents.

• 10+ years of progressive mechanical…
