Ann Goliak from Basecamp (co-founded by DHH himself, remember?!), is looking for summer interns in 2017. In her own word:
We have spots available in data, iOS programming, ops, product design, Rails programming, and support/social media. Internships are remote, paid, and require a commitment of 8-12 weeks of full time work between May and August 2017. We're flexible about vacations & such.
Read the medium article and don't hesitate to apply, that would be an incredible experience!
