Full Stack Ruby on Rails Software Engineer (Principal - Remote)

Welcome to Brightline! We are seeking a Full Stack Ruby on Rails Principal Software Engineer to drive technical direction across our platform, deepen our domain expertise in healthcare workflows, and raise the bar for the entire engineering team. We are primarily a Ruby on Rails shop and we are bought into keeping our tech stack simple so that we focus on shipping fast and having fun. Instead of betting on exciting new technologies, we favor straightforward solutions and defining standards so that the codebase and ecosystem are a joy to work with. We use Turbo, Tailwind, and ViewComponent to make beautiful UIs. Stimulus brings them to life and if we feel the need for it, we might sprinkle some React on top. We use Typescript where we think it benefits us, and default to Javascript otherwise. Our mobile apps leverage Hotwire Native to take advantage of existing web infrastructure.
