Around is an early stage, Series A startup backed by Ryan Hoover, Naval Ravikant, Wing, Credo, Initialized Capital, Slack Fund, Floodgate, and Forerunner Ventures.
Video calls designed for energy, ideas, and action. Video calls need to reflect a new era of working. That’s why we took video and made it less. Less traditional, less formal, less bulky, even less realistic. Less about blowing up people’s faces on a 70-inch HDTV, more about focusing and doing. Around is there for a quick session to supercharge all future-of-work applications. It’s just enough to be present but makes space for what’s important: the task at hand. Our sophisticated, AI-assisted audio technology developed over a period of 2 years completely transforms the possibilities and dynamics of a video call. Dedicated conference room equipment is no longer needed, and Around’s focused UX makes video calls fast and productive.

ActiveVideo | http://activevideo.com | Hilversum NL / Netherlands
Our company is looking for an allround AOSP/android systems developer who is comfortable going from C++ to Java, from init to stagefright, from vold to art and surfaceflinger to bionic.
Somewhat longer version:
We are building a platform where we run AOSP at scale inside a cloudy system, where graphics (GLES2) and audio/video media is offloaded to a custom thin client running on STBs. At the core of this product there is our own port of AOSP running in an x86_64 container instead of on an ARM SOC. We have tons of cool work to be done on this platform: custom services, optimizing resource usage, tweaking UI's, etc.
We are looking for someone who is strong at graphics and multimedia, is comfortable with both C++ and Java, and most important of all: who has loads of experience hacking their way around all levels of AOSP. We are located in The Netherlands, although with the current COVID situation I guess there is no hurry to move. Being in .eu time zone is a pro.
If you are interested, please drop mail me at email@example.com and I'll be glad to answer any questions and provide more details.
