What 'kind' of engineer are you looking for? Any specific platforms, languages or fields of interest? I went through the site and the portfolio consists of multiple (and very different) projects, so I'm just wondering how it works. :)
Ideally, we're looking for people that:
* bring expertise in at least one framework that we're likely to use, and
* love to start projects in a software stack that they haven't used before.
 Rails, django, iOS, Android, Xamarin, WPF, visual design skills
I mean, I mostly work with C# and F# on the back-end, but I created my fair share of WPF apps which I vastly prefer to web front ends. I also tinker with Scala in my free time, but I don't really know much about the JVM ecosystem.
I also readily admit I know next to nothing (neither have a feeling for) the UI/UX design, which is why I usually relied on libraries like MahApps; lately I had my eye on Material Design for WPF.
Considering my contract is up soon(ish), what you're offering looks tempting. :)
All things considered, I still feel compelled to ask: do you have a salary range or is it discussed individually? Or both, to a degree?
Both, to a degree. Specific salary offers are going to vary a great-deal with candidate experience. Our salary floor is $65,000 / year, and it ranges up from there. We also offer retirement and health-insurance reimbursement.
As a final bonus, you get to sign our confidentiality agreement which says that you'll keep our clients' confidential information secret!
Ideally we're looking for engineers that have a pretty-broad skill-set, that are happy to pick up new frameworks, languages, and code-bases as necessary.
The only qualification I would provide is that I don't have experience hiring outside of the US. If we decide to move forward with a hire from Europe, we'll need to work closely with a lawyer to figure out how to get all of our legal-ducks in a row.
