We wrote an ad server and have our own ad exchange. We also wrote our own time-series datastore (Erlang and C). Most of our code is Erlang, Java, and C. We're using Cassandra, Riak, CouchDB, Hadoop, and others.

A typical request will hit eight backends in that time period. If that sounds fun, you can reach me at joel at openx . com.

We are building a web platform that will help save civic America from the decentralization of modern communication. We are looking for one of two candidates:

1) Ruby on Rails backend developer. Must be willing to dabble in Javascript here and there, but mostly looking for the Ruby/Rails/database/architecture work.

2) Front-end guy. We have an awesome designer, and want to get his ideas into our code base as quickly as possible. Requires the obvious HTML/CSS/Javascript. HAML/SASS (with some familiarity with Rails -- not too much) is greatly appreciated, but certainly not a requisite.

This internship would be paid. Definitely. And we're looking for dedicated people who can start soon!

What we do: We're a young startup aggregating extraordinary activities, standardizing & enhancing the data, and redistributing it through our API.

* Python coding skills are required, Django and SOLR/Lucene knowledge would be great.

* We're also looking for some helping hands in our Ops department, helping to build a solid monitoring and auto-scaling solution for our AWS instances.

We're quite a small startup so you're not just a coding monkey and can expect to be involved in architecture decisions as well.

AppStores, in San Francisco, right by Union Square, need a marketing and community management intern, but you can make the roll as developery as you want. A developer evangelist would be hot.

We're a white label application store platform.

We just opened up a spot for an intern. We had two awesome ones from the east coast this summer and they went back to school.

  * internship is paid

  * a relocation isn't

Is any startup in the US taking interns from Canada? Good schools up north (UofT, W'loo, etc.) :)

Yes. We're inPulse (YCW11) and we hire Canadians. Hell, we're 3/4 Canadian at the moment. We're in Mountain View, CA.

We're looking for embedded software devs, Android devs and web/ops people. If you want an internship in the bay area, we pay market rate plus hook you up with living expense subsidies, free flights, food, etc. Send me an email: eric AT getinpulse.com

As a Canadian (Tdot).. I know it can be relatively difficult to get a job down here in SF. I was lucky enough to go to a US school which gets me OPT for a year. Then I can issue myself a TN-1 or H1B.

For Canadians.. try to get a TN-1!

I'm a Canadian who has worked in the US a number of times as an intern. J-1 visas were easy to get for me through my University career office and employer working together.

Ah neat! Do you know if this works for undergrads? And if the employer is a startup, does that add to the complexity?

P.S. This isn't for me, but for an undergrad I mentor.

I know plenty of bay-area startups hire undergraduate interns from the University of Waterloo (where I am).

I don't see it being a problem, though it's a little costly. You should contact a company like Cultural Vistas (http://www.culturalvistas.org/) who can get you the J-1 visa.
