Senior Frontend Developer – Transaction Management Platform

This is a fully remote position, open to applicants in Mexico.

📋 Description

• Develop and sustain microfrontend applications within a federated architecture by utilizing Module Federation and Rsbuild/Rspack, ensuring smooth integration with the host container application.

• Create intricate financial workflows that encompass transaction detail views, multi-level approval processes, receipt processing pipelines, and bulk action interfaces.

• Design and execute state management solutions that leverage custom store patterns, React Query for server state, and URL-synchronized search/filter engines — no Redux necessary; we prefer lightweight, specialized patterns.

• Operate within a TypeScript monorepo (pnpm workspaces) that includes a primary React application and shared core packages (API client, selectors, receipt processing engine, search logic).

• Develop real-time functionalities using WebSockets (STOMP/SockJS) for live transaction updates and optimistic UI patterns.

• Contribute to the internal component library and design system built on MUI v5 and Emotion, ensuring uniformity across the platform.

• Collaborate on maintaining code quality through ESLint, Prettier, TypeScript strict mode, SonarCloud analysis, and comprehensive PR reviews.

⛳️ Requirements

• Over 5 years of experience in frontend development, particularly with React.

• Strong command of JavaScript, TypeScript, and component-based architecture.

• Practical experience in consuming RESTful APIs and utilizing testing frameworks.

• Familiarity with Git, Agile methodologies (Scrum, Kanban), and contemporary development workflows.

• Experience in ensuring accessibility, responsiveness, and consistent styling across web applications.

• Ability to mentor junior engineers and foster team growth.

• Working proficiency in both English and Spanish.

• Self-motivated, impact-oriented, and adaptable to change.

🏝️ Benefits

• Competitive salary and stock options (ESOP) from day one.

• Multicultural team with daily exposure to Portuguese, Spanish, and English (our corporate language).

• Annual learning budget and internal accelerated development paths.

• High-ownership environment: we move fast, learn fast, and raise the bar — together.

• Smart, ambitious teammates — low ego, high impact.

• Flexible vacation and hybrid work model focused on results.
