There's your answer right there. Find remote employers who are hiring and pitch them on a paid listing with prime placement within the app.
Job boards are marketplaces. Supply = employers, demand = candidates. Charge supply for access to demand. You've built up the demand side of the marketplace first. Now you need to build the supply side. How are you pulling in listings right now?
Knowing that, IMO two key questions to ask yourself: how long/how many users can you scale to without monetizing? And how engaged are your users?
I think the play here is: land grab and sell your users to an aggregator at some point. So I'd grow it as fast as possible while minimizing distractions. Also, I'm assuming you've read Traction. I'd burn out whatever growth you're doing until it dries up or you're approaching the point where you can no longer support it without monetizing before digressing away from what appears to be working great.
