However, a subject of "Senior enterprise developer - C# (server) and javascript (browser)" is incredibly boring.
I also thought of "The most challenging programming you'll ever love." But I worry that will be viewed as arrogant (although I think it's a fair statement).
So...
What's the best subject line to get really good developers to send us their resume?
(The job's at http://careers.stackoverflow.com/jobs/60810/senior-developer-great-team-great-work-windward-studios?a=1cabOsh9K if you want more context.)
Whoever creates a good password manager first will own this market. I.T. managers at just about every company will line up to buy from you.
But you have to do it right. There are lots of bad solutions (see RoboForm) - don't duplicate them. Keep it very very simple. All we need is save a login & enter a login.
And the other critical piece, when we save a login we can set what ActiveDirectory group or individual to store it against. The group is so we can share company logins, but only with the appropriate people. The individual is so we can store our personal logins for our use only.
And provide synchronization so credentials entered by one person then go to the systems of others in the same AD group. (And to second computers for an individual.)
Implement this so it is trivial to install, administer, and use; and so you have the save by group/login - and you'll have a very successful product. We'll buy a copy for every user at my company.
