We're a profitable (and valley VC funded by some of the best funds in the valley) education startup that helps make class more engaging. We've got some really cool problems to work on and your work would be impacting a huge number of students daily.
Our dev team is in Toronto but we've also got an office in San Francisco so if you're really good we would be open to having someone work from there. If you're not based in Canada or the US but are willing to relocate feel free to contact us, because we do cover relocation expenses and will help you manage the work permit process.
