johnabowen··on Ask HN: Who is hiring? (October 2014)
Tyvak Nano-Satellite Systems -- Irvine, CA -- Full Time & Interns

Tyvak is currently ~16 engineers focused on building turnkey CubeSat/Smallsat solutions. We have several exciting new projects ramping up so it's time to grow the team further including full time positions in: - Spacecraft Controls - Embedded Software Engineering - Electrical Engineering - Mechanical Engineering - Spacecraft Systems Engineering - RF Engineering

As some background, one of our largest current programs involves rendezvous, proximity operations, and docking of two 3U CubeSats (http://www.nasa.gov/sites/default/files/files/A_Williams-A_T...). Another exciting area we are also starting to work is small launch vehicle avionics (http://digitalcommons.usu.edu/smallsat/2014/FromEarthOrbit/5).

Tyvak Nano-Satellite Systems – http://tyvak.com – Irvine, CA – Embedded Software Engineer

Tyvak provides Nano-Satellite and CubeSat space vehicle products and services that target advanced state-of-the-art capabilities for government and commercial customers to support operationally and scientifically relevant missions.

We build high performance small satellites using commercial off the shelf components running Linux. Our team is currently 11 engineers in various disciplines. You’d be the 12th and the second with a full time embedded software focus.

We’re looking for someone with specialization in embedded software development, preferably with experience in mobile and low-power SOC platforms, such as OMAP, DaVinci, and SAM series.

A full job description is available at http://tyvak.com/careers. Please respond to HR@tyvak.com if you’re interested.

Very dense = high ballistic coefficient = longer orbital lifetime

Though I generally agree that CubeSats are relatively safe / low junkyness.

In fact, most (US only maybe?) CubeSats have to demonstrate an orbital lifetime of less than 25 years to get a frequency allocated. (The FCC regulating space debris via frequency allocation is an interesting debate for another thread.)

One of the largest CubeSat (the form factor of these satellites) conferences is actually happening right now. It can be live streamed or replayed here: http://mediasite01.ceng.calpoly.edu/Mediasite/Catalog/pages/...

You can find out more about who else is building this type of hardware here: http://cubesat.org/index.php/collaborate/suppliers

johnabowen··on YC Rejection Emails Are Out
Do all of the team members get an email, or just the one who submitted?
johnabowen··on Loosecubes is shutting down
I agree that it’s surprising. I hope we get a postmortem; I’d like to know why they are closing the doors. Lack of traction (seems like they had some though)? Trouble monetizing?
