The Critical Mass technology team is looking for an inspired, motivated, and experienced web developer to join our team. We are an experience design agency with a focus on the customer, which means that multi-discipline collaboration and prototyping are at the heart of our process. This role will join a talented team working on AT&T. We're using the latest technologies including React, GraphQL, Gatsby and a clean component-based approach to deliver reusable, innovative, and responsive experiences. Web performance & accessibility are also key concerns because of their respective importance to user experience and perception of a premium experience.

Our team culture thrives on a balance of collaboration and focused time which means you won't be spending your days turning PSDs into HTML or simply pulling tickets off a JIRA queue - rather you'll be part of the design and prototyping process using data and user research feedback as input. You'll help balance the team between innovation and pragmatism. Additionally, the team has several remote members, so we use screenshares and Slack as to keep communication flowing. We have a lot of fun and hope you'll join us.
