Job description

iENG Design is seeking a qualified professional to join our Engineering team. iENG's method of engineering is unique: We begin with the end in mind, and we challenge everything. We take time to understand the project we want to deliver. We understand the owner's views, use of building, the owner's operation and maintenance capabilities. We look at first cost v. operation cost v. life cycle cost. Every iENG project has a best value and best design---and that's what we deliver. An IMI Company, iENG serves nationwide Fortune 500 clients across the Institutional, Commercial and Industrial markets---there isn't a project our team cannot tackle.

iENG Design is headquartered in Chesterfield, MO and has branch offices in Granite City, IL, Nashville, TN and Charlotte, NC. Services & Capabilities include: Engineering & Design, VDC/BIM Coordination, Construction Support, Scheduling, Commissioning, Retro Commissioning and Inspection Services. iENG currently ranks as one of the largest engineering/design firms by revenue in the region.

We are currently looking for a Senior Structural Engineer to join our Engineering team located at our office in Granite City, IL or in our Chesterfield, MO office. Our ideal candidate for a Senior Structural Engineer is someone who has at least 5 years of experience in a fast-paced, design/build mechanical contracting company or similar.

Reporting directly to the Director of Structural Engineering, this position carries a higher level of ownership and technical responsibility than a staff engineer role - you will serve as a lead-level contributor on complex projects, a quality-control resource for the department, and an informal mentor to less experienced engineers on the team. This is the right role for a licensed engineer who is confident in their technical abilities, thrives in a multi-discipline project setting, and is looking for the opportunity to take real ownership of structural design challenges. You will work across the full scope of the department's structural portfolio and play an important role in shaping how the team approaches its most demanding assignments. Looking ahead, this position is also a natural steppingstone toward department leadership.

Primary responsibilities for iENG’s Senior Structural Engineer include:

Advanced Structural Design & Analysis

• 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

Quality Control & Standards

• 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

Primary qualifications for iENG’s Senior Structural Engineer include:

• 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
• Demonstrated 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,ASCE7, 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, CAESAER 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

COMPENSATION AND BENEFITS

• Salary Range: $115,000 - $145,000
• Employee Stock Ownership Program
• Discretionary Annual Bonus'
• Health Insurance
• Vision Insurance
• 401k with Discretionary Company Contributions
• Paid Time Off (Vacation; Sick Time)

• Tuition Reimbursement Program
• Employee Assistance Program
