As a Senior Front End Engineer at Publicis Sapient, you will work with some of today's top brands and take ownership for the design, development, and implementation of new applications that turn massive real-time datasets into something beautiful and intuitive. Ranging from large scale e-commerce frontends to slick data-driven visualizations, you'll code some of the most complex stories, serve as a constant advocate for code quality and user experience, conduct pull request reviews, mentor junior developers, and set up front-end tooling and continuous integration. Your Impact: Code the most complex pieces of the application. Whether it's a dynamic visualization, a tricky third-party integration, or a crazy animation sequence - you're up for the challenge and you'll take pride in the finished product. Test your code and help ensure that the right code is being tested across your project. You also help make sure that integration tests are running, and that everyone on the team tests before they push code (either manually or as part of a pre-commit hook). Model the behavior and practices that you want to see in the organization. Want to follow TDD? Do it, and demonstrate the results to your team and clients. Itching to adopt a new tool or framework? Try it out and show the value. Estimate or point your own work, and be able to sanity check estimations from more junior developers to make sure that they're setting themselves up for success.
