Work on having some inbound candidate flow by increasing awareness of your engineering team's brand. Start an engineering blog, and make sure you put out some high quality content, with a "we're hiring" link at the bottom of every post. Make sure that you measure and try to drive traffic to these posts. Have everyone on your team that is interested help contribute a blog post or two. Encourage open source contributions from your team. That will help them connect with other talent that might be looking. Keep prospects warm even while you have no headcount needs so keep your pipeline from ever completely drying up. And lastly, hire remote (or generously relocate) if you can't find enough developers in your local area.
