Senior Typescript & Rails Developer

I'm looking for a senior developer to modernize a React & Rails application. The first steps will be to convert the Javascript codebase to Typescript and then migrate to Vite from Webpack. Once that phase is complete, we have a long list of new features to be built. The product is in a financial industry and has tens of thousands of active users. When applying, please include the word pickle so that I know you read the job description.
