Honest is looking for a Rails contractor (3-month, 40h/week commitment)

Honest is building the “customer service agent’s best friend”: contextual, real-time assistance and shortcuts for digital customer service teams.

We’re looking for an experienced Rails contractor to come help us improve our Rails app, initially with a 3-month, 40h/week commitment.
