I've appreciated the culture and how it's evolved at Zipline over the past 5 years that I've been there. If you want to work on a UAV based medical delivery system, it's a pretty cool place.

If I weren't at Zipline, I'd probably be at Reliable Robotics, but that's more because I know the founders and lots of other employees there, and they have a strong team that's set up for success.

I'm biased towards robotics companies since I'm an embedded software engineer, though.
