Platfora is hiring JavaScript engineers to Distributed system engineers. They are in San Mateo, California and closed their series A with Andreessen Horowitz leading.
They offer solid benefits with competitive pay and have some of the smartest people I've met on their team.
Also they need serious JS engineers, people that know the ins and out of the language and can build entire applications out of JS.
