You design the pieces a building gets assembled from — roof trusses, wall panels, floor systems — engineering each component to carry its loads and actually fit together on site. Where a building is worked out, part by part.
Most of the work happens in design software — laying out components, running the structural checks, and producing the shop drawings a plant will build from. You sit between the architect's intent and what's buildable, and a small error here becomes a problem on site. The craft is partly solving how the pieces actually connect before anyone cuts material.
At a truss or component plant the pace ties to production deadlines; at an engineering firm it's more varied. The codes and load cases are exacting, a redesign late in the game ripples through the shop, and you're balancing strength, cost, and constructability at once. Some roles are pure production drafting; others carry real engineering judgment.
It tends to fit the precise and practical — people who like the puzzle of making parts fit and carry load, more than big-picture architecture. If you want design glory or wide variety, the component focus can feel narrow. But if there's satisfaction in a structure that goes up clean because your details were right, the work delivers it.
