Initial feedback - It's a fairly clean page, but it's cluttered, and a little disorganized.
My eye is immediately drawn to the giant orange banner. So it takes me a second to adjust and start looking around. Finally I notice "Positions Available", but it's at the bottom right - literally one of the last places my eye naturally falls. I then need to scroll down to see the whole list, but it sort of blends in with the rest of the page.
I like how you've got a bunch of fun shots of your office, and of the team having a good time (it sure looks like a nice place to work, and the Seaport is a nice enough area, transportation and lunch/afterwork-wise that it would enticing for someone who wanted a job in the city), but to me I had to actually work a little bit to find the content I cared about on the page, so my interest fades fast.
If I had a suggestion for you, it would be to reduce the huge banner, and maybe re-organize the page. Make the actual job listings more front and center, and put the stuff detailing how great your team is below it - or on a seperate page that you actively pimp out from your job postings page... (Now that you've seen the jobs, check out why you should work here! sort of thing).
But I'm no design specialist. So maybe I'm way off base here. Good luck with the company, that sounds like a cool space to be in.
