One problem the current job search sites have that you might be interested in tackling, is that they lack a way of objectively measuring the capabilities of the applicants.
There are software engineers that are 100x as productive as some others, but the pay for all of us is always within a factor of 3 or 4. If you can solve that problem, employers will love you for helping them hire better engineers, and qualified applicants will love you for getting them higher-paying jobs.
