Structural Engineer Job Description

A Structural Engineer is the person who decides how a building stays up. The architect lays out the spaces; the structural engineer works out what holds them in the air, sizing every beam, column, slab, wall, footing and connection so the finished structure resists the loads it will see over its life. Those loads include self-weight, occupants and furniture, snow, rain, wind and earthquake ground motion. They come from ASCE 7, which its publisher describes as the nationally adopted loading standard for general structural design.

The work runs in phases that track the architect's. In schematic design, the engineer picks a structural system: a steel moment frame or braced frame, a concrete shear-wall core, a post-tensioned flat plate, mass timber, or light-frame wood over a concrete podium. That choice sets floor depths, column grids, the location of the lateral system and the demands on the foundations, so it gets argued out early with the architect, the owner and the contractor's estimator.

Design development and construction documents are where the numbers get done. The engineer builds an analysis model in a program such as ETABS, RAM Structural System or RISA-3D, runs the load combinations, checks drift and floor vibration, and designs members against the material standards: ACI 318 for concrete, AISC 360 for steel, the NDS for wood and TMS 402 for masonry. Hand calculations still earn their keep as quick checks and as proof that the software output makes physical sense. The product is a drawing set, modeled in Revit or drafted in AutoCAD, plus a calculation package that a building department plan reviewer reads before a permit is issued.

Foundations pull in the geotechnical engineer. The soils report sets allowable bearing pressures, pile capacities and settlement limits, and the structural engineer designs spread footings, mats, drilled piers or driven piles that fit those limits and the column reactions coming down from above.

Construction administration is where the drawings meet the job site. Contractors send requests for information when a detail does not fit, fabricators submit shop drawings for steel, rebar and precast, and the engineer reviews each one against the design intent. When a plumber cores through a beam or an anchor bolt pattern lands in the wrong spot, the engineer of record writes the repair. Site observation visits confirm that the work generally follows the documents, while the contractor keeps control of means and methods.

Existing buildings form their own specialty. Renovations, additions and changes of occupancy all require someone to establish what the original structure can carry, often from incomplete record drawings and a few exploratory openings, and to design strengthening where capacity falls short. Seismic evaluations of older buildings using ASCE 41 belong here as well.

At the end of it, a licensed engineer seals the drawings. That seal carries legal responsibility for the life-safety performance of the design, which is why the job pairs technical depth with disciplined documentation and a paper trail for every decision that changes during construction.

The usual starting point is a bachelor's degree in civil engineering from an ABET-accredited program, with electives in steel design, reinforced concrete, timber and structural dynamics. Architectural engineering programs with a structural track are another route in. Some engineers add a master's degree in structural engineering before their first job, which buys deeper coursework in seismic design, finite element methods and prestressed concrete and can shorten the learning curve on complex buildings.

Licensure shapes the career more than any degree does. BLS describes the standard sequence as a degree from an accredited engineering program, a passing score on the Fundamentals of Engineering (FE) exam, several years of relevant work experience, and a passing score on the PE exam. According to BLS, a PE may oversee the work of other engineers, approve design plans, sign off on projects, and provide services directly to the public. Graduates typically sit for the FE exam, written by NCEES, in their final year of school or soon after, and their state board then recognizes them as an Engineer Intern or Engineer in Training while they build experience under a licensed engineer.

For the PE itself, structural engineers can choose between the NCEES PE Civil exam taken in its structural depth and the NCEES PE Structural exam. The right choice depends on where you plan to practice and what kind of buildings you want to seal.

A few states add a separate structural license on top of the PE. Illinois licenses Professional Engineers and Structural Engineers separately through its Department of Financial and Professional Regulation. Washington's engineering board requires applicants for its Structural Engineer license to already hold a Washington PE and to have at least 2 years of progressive structural engineering experience beyond the PE requirement. Read your target state's rules before you pick an exam path.

A typical progression looks like this:

• Early career, roughly years 0 to 4: calculations, modeling, drafting coordination and shop drawing review under a licensed engineer's supervision.
• Mid career, roughly years 4 to 8: PE in hand, running smaller projects and client meetings with a senior engineer reviewing the work.
• Senior, roughly 8 years and beyond: engineer of record on larger projects, mentoring younger staff, and for some, a path to associate, principal or firm ownership.

The technical skill set is specific:

• Codes and standards: the International Building Code, ASCE 7, ACI 318, AISC 360, the NDS and TMS 402, plus ASCE 41 for existing buildings.
• Analysis software: ETABS, SAP2000, RAM Structural System, RISA-3D, and bridge or foundation programs as the practice requires.
• Documentation: Revit, AutoCAD, and a calculation tool such as Mathcad.

Soft skills matter as much as the math. Structural engineers write calculation packages and condition reports that a plan reviewer or a lawyer may read years later, and they explain structural limits to architects and owners who want thinner floors and fewer columns. Involvement with a local Structural Engineers Association or ASCE's Structural Engineering Institute helps with continuing education and with finding mentors outside your own firm.

The federal projection for the broader field is positive. BLS projects employment of civil engineers, the occupation that includes structural engineers, to grow 6 percent from 2025 to 2035, faster than the average for all occupations. The occupation held 380,600 jobs in 2025, and BLS expects about 22,700 openings each year over the decade, many of them from the need to replace workers who move to other occupations or leave the labor force, such as to retire. Because those figures cover every civil specialty, read them as a proxy for structural work rather than a count of structural jobs.

The technical ground has moved too. ASCE/SEI 7-22 added a new chapter of tornado provisions. The International Code Council's Building Safety Journal summarized the chapter as covering tornado loads and effects, including new tornado wind speed maps, and noted that the edition also brought multi-period response spectrum data that eliminates the need for the Fa and Fv site coefficients. For projects it applies to, the tornado chapter is a separate check to run and document.

Artificial intelligence is the other big shift, and the profession's own bodies are trying to set the terms. In April 2026 the National Council of Structural Engineers Associations released a 25-page report, "The Future of Structural Engineering 2026." NCSEA's summary of that research says AI adoption must be governed, not improvised, with an emphasis on accountability, professional judgment and trust. It found that a common approach was relying on native AI embedded in tools engineers already use rather than standalone specialist tools; one leader quoted in the summary said integrated, even average, AI is more useful than advanced tools that are hard to adopt. In discussions for the same research, senior engineers stressed that young engineers must develop a strong command of fundamentals before relying on AI.

The report also flags two pressures that affect careers directly. It says workforce development has shifted from a talent issue to a strategic capacity and risk issue, requiring mentoring, communication skills and clearer career pathways. And it calls value perception the profession's central vulnerability, intensified by AI-driven efficiency and long-standing client misunderstanding of what structural engineers do. Put plainly, if software makes drawings faster, firms have to explain why the engineering judgment behind them is still worth paying for.

For someone building a career, the practical reading is straightforward. Get licensed as early as your state allows, since the seal is what separates an engineer who can take responsibility from one who supports someone else's. Learn one analysis platform deeply enough to catch it when it is wrong, because that skill still matters when AI features appear inside the tool. Pick up existing-building evaluation and seismic or wind specialization if you work in a region where those hazards govern. And practice explaining your design choices to non-engineers, a skill that speaks directly to the client misunderstanding NCSEA describes.

Employers range from structural consulting firms and multidisciplinary architecture and engineering practices to state transportation bridge offices, federal agencies, general contractors with in-house engineering groups, and steel and precast fabricators. A structural engineer can move from design to construction support or public-sector plan review, and the same code knowledge carries across each setting.

Dear Hiring Committee,

I am applying for the Structural Engineer opening at Harborline Structural. I hold a PE license and have spent six years designing commercial, education and light industrial buildings at a mid-sized consulting firm, most recently as the lead engineer on a four-story mass timber classroom building over a concrete podium.

On that project I developed the lateral system from schematic design forward, building the ETABS model, sizing the concrete shear walls in the podium, and working out the diaphragm and collector design for the cross-laminated timber floors above. The architect wanted exposed timber ceilings with no dropped beams in the classrooms, so I coordinated with the mechanical engineer to route ducts through a shallow zone along the corridors and adjusted the panel spans to fit. The building department accepted the structural set after one round of comments.

Construction administration is the part of the job I have come to enjoy most. I reviewed more than a hundred shop drawing submittals on the classroom project and answered the contractor's structural RFIs within two working days. When an anchor bolt layout at the podium transfer level came in misplaced, I designed a post-installed anchor repair the same afternoon so the timber erector did not lose a week.

I am drawn to Harborline because of your work on seismic upgrades of older concrete buildings. I have completed two small ASCE 41 evaluations and want to make existing-building work a larger part of my practice, under engineers who have done it for years.

I would welcome the chance to talk about how I can contribute to your team. Thank you for your time and consideration.

Sincerely, Jordan Alvarez, PE
