Good advice so far, as usual.
What sort of structural career do you want? You say you work at a design build firm - is it a designer led design build firm or a builder led design build firm? In other words, do you work in an office of design engineers with a construction manager who hires the subs, oversees the build, etc., or do you work for a contractor that hires designers and then builds their design? There are pros and cons to both. If designer led, you're going to get exposure to and experience in design and analysis methods. This will be helpful if you take the SE or Civil/Structural PE. You'll exposure to construction, too, but it will be limited to what your firm builds, which may narrow your view on what can be done and how it can be done - I've learned quite a bit from exposure to multiple builders. If builder led, you're going to get in depth knowledge of how a building is actually put together. This will be good if you want to be a contractor (lots of good engineers have made great contractors), and can set you up to the Civil/Construction PE exam. In either case, the design build environment will help you learn to design economically. A lot of firms that work in the design-bid-build space tend to be more conservative. There's a lot of reasons for this, and many of them quite valid, but most of them go away in design-build which gives you a chance to better understand structural efficiency. Either of these are good choices, but it depends on what you want out of your career. It's not impossible to change later, but it gets harder every year that goes by.
