Job Description

We are looking for a Senior Software Engineer with solid front-end experience, an analytical mind and technical creativity, capable of working independently and proactively through all phases of the software lifecycle, from requirements analysis to the evolution of innovative solutions.

The professional will work on front-end initiatives with a strong emphasis on reusable components composed of multiple products in Angular and React, including documentation, accessibility, and coordinated evolution across both stacks.

You should demonstrate strong problem-solving ability, intolerance for inefficiencies, and excellence in written and verbal communication, as well as contribute to improvements in code and tools that support the pace of business operations and ensure the success of applications for the company.

Qualifications

  • Works in a multidisciplinary environment, participating as a Software Engineer in front-end applications and shared component libraries (Angular and React), actively participating in discussions, proposals, and planning.

  • Act as a point of reference for technical questions and resolve critical impasses, providing specialized guidance on both stacks when necessary.

  • Participate in the entire software development cycle, from conception to deployment and operation, including definition of public component APIs, package versioning, and alignment with UX/UI and consumer teams.

  • Develop scalable solutions for millions of users.

  • Effective communication and careful analysis of transactions from Business, Product, and other teams.

  • Application of SOLID principles and Design Patterns in implementation, testing, and maintenance, in both Angular and React, preserving behavior parity and accessibility when there are equivalents in both libraries.

  • Ensure delivery quality through testing, reviews, and regression criteria (including impact on NPM consumers).

  • Share knowledge and support team development in React composition patterns, hooks, and packaging, in addition to Angular patterns already adopted.

  • Perform code reviews and apply specific case tests, with attention to public API, performance, and package size.

  • Keep documentation of services and component libraries up to date (e.g.: component catalog, usage examples, guidelines).

  • Constantly seek technical and performance improvements (re-renders, tree-shaking, library building, pipelines).

  • Demonstrate willingness for continuous learning and constant improvement.

What are we looking for in you?

  • Ability to work in a team, as well as skills in planning and organization.
  • Proficiency in TypeScript with Angular 15+ and React 18+ (hooks, composition, strict typing of props and component contracts).
  • Knowledge of CSS preprocessors (e.g.: LESS, SASS) and ability to follow tokens, themes, and style conventions shared across products.
  • Development of unit tests with Jest/Jasmine in the Angular ecosystem and Jest or Vitest with React Testing Library in the React ecosystem.
  • Dependency management with NPM and/or YARN (and familiarity with monorepo flows/package publishing when applicable).
  • Experience in integration using REST APIs.
  • Familiarity with UX and UI concepts, including component states, accessibility (ARIA, keyboard, focus), and visual consistency across frameworks.
  • Knowledge of interface prototyping using Figma or other design tools.
  • Experience with CI/CD pipelines, especially using Jenkins.

It will be a differential

  • Experience with corporate component libraries consumed by multiple products and maintenance of NPM packages with stable API.
  • Experience with microfrontends.
