I'm adding this in a new answer because I think this needs airing. I've received responses claiming to be from StackOverflow careers and claiming that Quantlab is legitimate. However, what they claim in the response and what Quantlab told me in a response conflicts pretty seriously.
The first response I got from generic Stack Overflow careers was the following:
We will speak to this employer and
find out more information. We believe
they are trying to fill positions for
-- Stack Overflow Careers firstname.lastname@example.org
However, the job they linked to is for a C# developer or a .net developer. I list both of those as one of my Dislikes in my careers Stack Overflow profile. If they are trying to fill that position, it makes no sense whatsoever for them to contact me.
Shortly after that I received a second response from Atilla (still email@example.com) with the following:
Thank you for your response, we always
value our community!!
These guys are the definition of
"Stealth Mode", I've spoken to them
several times, they are real and not
phishing. They just got funding and
are looking to build out a team of
programmers - Bootstrap Mode??.
Either way, they are real: Thanks for
the Help in keeping our boards clean,
we appreciate it!!
Okay, I supposed I can buy that. A small team that just had funding and was trying to bootstrap could definitely not have much web presence. But then Quantlab responded to my initial response to their invitation telling them in no uncertain terms that I was convinced they were a scam and didn't appreciate the attempt. They responded with this:
Hi Daniel -
I certainly understand your concern
regarding our lack of web presence.
Actually we have been operating a very
successful proprietary trading firm
for 12 years. Because we trade our own
capital and don't license any of our
technology we are basically in
business for ourselves. Great when you
think about, but certainly makes
recruiting a challenge.
My contact information is below, try
my email, it works - even get it on my
Kate Brummett Recruiting Manager,

Wait, what? Someone needs to get their story straight! Either you've been around for 12 years and you're a very successful firm or you just got funding and you're in the process of bootstrapping. Which is it? And the fact that your e-mail and blackberry work tells me nothing. Mine do too, but that doesn't mean I'm not a spammer or scammer. And why are you giving out an address that points to the University of St Thomas? And a web address that leads to nowhere? If they were a real firm that was just going stealth mode, then they shouldn't be giving any address or web address at all! There's something very rotten going on in Denmark. I don't know what it is, but too much of this information conflicts, it doesn't add up. Someone is either very confused or not telling the truth.
If they are legitimate, then I apologize - but from what I've seen, I sincerely doubt it. And if they are a scam and someone bites they could screw some people over pretty seriously.
Edit: After a little more searching - looking for 'Quantlab Financial scam' ironically - I turned up a NASDAQ listing for them. On an a Securities and Exchange Fraud lawyer's site. They don't appear to be listing them as a fraud, but as legitimate though. And I found a few blog posts or articles listing them as a firm that does high frequency trading. I'm a little more willing to believe they aren't a scam.
But either they or Careers needs to work a little harder in the future to keep things straight. Because up until that point all the information I could see pointed straight to a scam.
Further Edit: I'm pretty convinced they are real now. See first post.
