What about a sliding scale for the commission? The higher the salary the bigger it is? So a junior engineer would practically be free, but a senior engineer would bring in more revenue than the subscription.

Then the company is incentivized to use you for junior hires. Maybe you'll get a few freeloaders who only want to hire juniors, but even those will eventually be seniors who love your platform, and at the same time, will boost your stats on the number of juniors you got jobs for.
