Senior Full Stack React/Node Developer

We are seeking a senior front end developer, well-versed in React, to join our growing development team. We work in a collaborative, ego-free environment and would expect you to have a respectful and open mind. Wondersauce places a large emphasis on clean design, intuitive interactions, and custom solutions to meet the needs of our wide range of clients. We are looking for someone who has a strong foundation with the desire to learn and grow as a developer with our team. Perhaps most importantly, you have an eye for detail and the ability to make beautiful designs come to life through code. If you enjoy working on both server-side structure as well as client-side styling and interactivity, we’d love to hear from you.

We are currently mapping out our strategy for future web applications, and would like to build out our React capabilities. You would play a leading role in helping establish best practices.

The Wondersauce dev team spans four offices, New York, Columbus, Los Angeles and Costa Rica, and is comprised of a range of talent focusing on both backend and frontend development. As a discipline, we are extremely open and collaborative, from sharing cool finds in emerging tech and debating new methodologies, to helping each other with tough bugs and reviewing each other's code. Developers are involved on projects from day 1, collaborating with all disciplines and contributing to the overall success of a project, working closely with strategy, UX and design to come up with the best solutions for the problems at hand. 

The projects that we work on span a wide range of industries and technologies -- recently we’ve built an application in Python and Angular to automate social management, a Wordpress multisite for a well-known CPG brand’s B2C and B2B sites, and are creating an atomic-design-driven pattern library for an ecommerce brand in the fitness space. Aside from client projects, we are excited about experimenting with new technologies like voice, AI and AR, focusing on making all of our sites ADA compliant so we can help make the web accessible for more people, as well as working as a team to create a library of reusable code to help speed up our workflow and knowledge share across projects.
