Ready to accelerate your career?

We already help over 20,000 large and growing businesses operate with agility and financial clarity through locally issued corporate cards, bill pay, financing, and a powerful B2B platform built for scale.

Clara is backed by some of the most successful investors in the world, including top regional VCs like monashees, Kaszek, and Canary, and leading global funds like Notable Capital, Coatue, DST Global Partners, ICONIQ Growth, General Catalyst, Citi Ventures, SV Angel, Citius, Endeavor Catalyst, and Goldman Sachs - in addition to dozens of angel investors and local family offices.

We’re building the financial infrastructure that powers high-performing organizations across the region. We invite you to join us if you want to be part of a fast-paced environment that will accelerate your career and support you to do some of the best work of your life alongside a passionate and committed team distributed across the Americas.

What you'll do

We’re building a talent pipeline for top-tier Senior Frontend Engineers who are eager to shape the future of user-facing experiences at Clara. If you're passionate about frontend architecture, modern React development, and seamless user interactions—and would like to be considered for future openings—this is the place to start.

We are looking for a Senior Frontend Developer to join our engineering team and help build and evolve our financial transaction management platform. You will work on a suite of microfrontend applications that power corporate expense tracking, compliance, and auditing workflows for multi-national organizations

Build and maintain microfrontend applications within a federated architecture using Module Federation and Rsbuild/Rspack, ensuring seamless integration with the host container application.
Develop complex financial workflows including transaction detail views, multi-level approval flows, receipt processing pipelines, and bulk action interfaces.
Design and implement state management solutions using custom store patterns, React Query for server state, and URL-synchronized search/filter engines — no Redux required; we favor lightweight, purpose-built patterns.
Work across a TypeScript monorepo (pnpm workspaces) containing a main React application and shared core packages (API client, selectors, receipt processing engine, search logic).
Build real-time features using WebSockets (STOMP/SockJS) for live transaction updates and optimistic UI patterns.
Contribute to the internal component library and design system built on top of MUI v5 and Emotion, ensuring consistency across the platform.
Collaborate on code quality through ESLint, Prettier, TypeScript strict mode, SonarCloud analysis, and thorough PR reviews.

Must haves

5+ years of experience in frontend development, with a focus on React
Strong proficiency in JavaScript, TypeScript, and component-based architecture
Hands-on experience consuming RESTful APIs and working with testing frameworks
Familiarity with Git, Agile methodologies (Scrum, Kanban), and modern development workflows
Experience ensuring accessibility, responsiveness, and consistent styling across web applications
Ability to mentor junior engineers and support team development
Working proficiency in English and Spanish
Self-driven, impact-focused, and adaptable to change

Nice to haves

Experience with Node.js to enhance frontend-backend collaboration
Familiarity with AWS services like Amplify, S3, and CloudFront
Knowledge of Material UI or similar design systems
Understanding of OAuth, OpenAPI, and Swagger
Understanding of internationalization (i18n) and multi-locale support.
Experience with SonarCloud or similar static analysis tools.
Exposure to fintech, compliance, or expense management domains.
Background in secure or financial web application development
Interest in using AI tools to accelerate UI development and testing

Clara’s Hybrid Policy

Claridians in a hybrid mode split their time between working from the office, talking to or visiting customers, or working from home. This hits a balance between bringing people together for in-person collaboration and learning from each other, while supporting flexibility about how to do this in a way that makes sense for each individual and team.

We don't enforce a minimum number of days for most roles, but you're expected to spend time at the office organically, and be at the office most days during your ramp-up or when required by your leader.
