Network (which really means just keep in touch with folks you have worked with or met).
At your current employment situation, keep your ear to the ground. You don't need to move to a big company (they have layoffs too) but you want to be aware of what is happening.
Ask your boss questions about the business, and do your own research too. If your company is "default dead" then ask how you can help make it "default alive".
Cut your unneeded expenses.
Start a company if you have the drive to so, don't worry about the macroeconomic climate.

Invest in yourself. Keep current and research what skill sets are in demand. Look at companies hiring even if you don't need to move. Don't wait until you find yourself with outdated skills knocking on people's doors.
Seeing infrastructure brands like Cisco, Java, and RedHat all over the mainstream financial press made me worry the tech would suffer for the sake of marketing. Indeed, I saw companies investing in tech from those brands before their use cases justified it, because they could show investors their name brand hardware in the data center and cash in on that brand recognition. But the cost doesn't matter because you'll get rich when you IPO next year, right?
Of course it was a different world back then because the hardware and software were a much larger portion of spend for internet companies. Signs may be different now.
That said, "History may not repeat itself, but it does rhyme."
You have to seek diversification, one way to do it is to short the system so that people can feel safe in their particular idiosyncratic exposure.
That's what we do.
I visited your website but from a brief perusal it wasn't clear exactly what you can hedge, other than "particular systemic and market risks".
For example, way too many people were piling into SF real estate, right at the time when they felt the most rich from their employee stock options. http://www.snow.ventures/blog/2016/1/13/stopbuyingsfrealesta...
We have a systemic hedge product, and are working on building out the capabilities to create unique portfolios to hedge idiosyncratic risks.
From your website, looks like the systemic hedge is focused on SV right now, which makes total sense. Bet once you get it nailed there, there's plenty of blue ocean in the other tech hubs.
Also, I bet you've seen this, but this book really opened my eyes to the fact that your expected lifetime income was another asset to think about diversifying: http://www.amazon.ca/Are-You-Stock-Bond-Financial/dp/0133115...
