Front - End Developer

As a Senior Software Engineer on the Frontend team, you will build elegant and intuitive user interfaces for web portals that support internal and external users. You will take full ownership of features from concept to delivery, architect scalable and maintainable frontend solutions, and be a driving force behind the evolution of the product.

A core challenge of this role is leading the migration from a monolith to a micro-frontend architecture and building a new design system from the ground up. You will set the technical bar through code reviews, define coding standards and architectural guidelines, and ensure that all code is designed with testability in mind.

This role is based in our Sao Paulo, Brazil office with 4 days per week in office required. You will report to the Frontend Engineering Lead in Brazil and must overlap with Mountain Time Zone (US) for at least 4 hours daily.
