Burlington, MA - C++ software development of engineering desktop products.
Exa Corp (www.exa.com) is a CAE software company (primarily used for automotive design). We have a variety of positions open on our website, but I'm particularly focused on filling a couple of spots in my group. Here's the posting:

I manage a team of three (including me) and I'm looking to add two developers to support our rapid growth (including a couple of big upcoming projects). Note that the job description lists 5-7 years experience, but because I have two open spots, I'll likely hire one more junior candidate as well.
Shoot me an e-mail if you have any interest or want more details -- the e-mail in the posting (REDACTED_EMAIL), will come to me.
