Qualifications

• Bachelor of Science degree in Civil or Structural Engineering.
• Licensed Professional Engineer (P.E) for Structural or Civil Engineering.
• 5+ years of structural engineering experience in an industrial or commercial setting.
• Experience with complex industrial structural design, notably pipe racks, skids, platforms, and equipment supports.
• Proficiency with structural analysis software such as RISA, STAAD, RAM, or similar.
• Expert working knowledge of AISC,ASCE 7, IBC, and relevant structural codes.
• Experience in a mechanical contracting, EPC, or design/build environment is preferred but is not required.
• Familiarity with pipe stress analysis tools such as AutoPIPE, CAESAR II, or similar is preferred but is not required.
• Experience with modular or skid-mounted structural design and exposure to seismic design in high-hazard zones (CDC C-F) is preferred but is not required.

Responsibilities

• Lead structural calculations and analysis for complex pipe racks, equipment skids, pipe and equipment stands, elevated platforms, and other industrial support structures.
• Design and evaluate hanger systems including anchoring, guides, and specialty restraints for demanding piping and equipment configurations.
• Incorporate all applicable structural loading requirements — dead loads, live loads, wind loads, seismic forces, and pipe stress analysis results — into comprehensive, code-compliant designs.
• Prepare and seal structural drawings and calculations as a licensed P.E., taking technical responsibility for design deliverables.
• Serve as a technical resource for the team on code interpretation, load path analysis, and complex structural details.
• Perform detailed technical reviews and QC checks on calculations and drawings prepared by staff engineers, providing constructive and actionable feedback.
• Support the Director in maintaining and evolving department calculation templates, design standards, and quality control procedures.
• Identify inconsistencies, technical gaps, or efficiency opportunities in current workflows and bring recommendations to the Director.
• Ensure all design deliverables reflect applicable codes (AISC, ASCE 7, IBC, OSHA) and department standards before issuance.
• Provide day-to-day technical guidance, coaching, and informal mentorship to staff-level structural engineers.
• Support junior engineers in developing their calculation and design skills through direct collaboration and review feedback.
• Work closely with piping, mechanical, and process disciplines to ensure seamless structural integration across multi-discipline project teams.
• Participate in constructability reviews, project coordination meetings, and interdisciplinary design reviews as the structural subject-matter expert.
• Manage the structural scope on assigned projects, coordinating workload and deliverable schedules with the Director and project management teams.
• Act as the primary structural point of contact for project teams on assigned work, making and communicating technical decisions with confidence.
• Contribute to the department's expansion into modular plant structural design, helping to define technical approaches and set precedents for the new service line.
• Support the Director in recruiting, onboarding, and developing structural engineering talent as the department grows.
